Toyota Tacoma owners have reported 28 problems related to differential unit (under the power train category).
The rust on the rear end assembly is so severe that the brakes are compromised, and the back up emergency brake system has failed. The rust on the differential housing is so severe that the fluid has leaked out and the gears are at risk for catastrophic failure. The spring mounts to the axles are also rusting severely, creating a risk of lost control should either side break away. It takes great effort when braking, and the vehicle pulls severely due to rust causing the loss of integrity of the braking system. The brakes, once applied, do not release evenly, creating uneven brake wear, shuddering and shaking, resulting in poor control, excessive and uneven tire wear, I. E. , tires locked and dragging, scalloping. On wet, and I fear, icey, surfaces, the truck has slid sideways due to one or more wheels not releasing.

While driving eastbound on the 210 freeway in glendora, CA at approx 35mph the vehicle came to a sudden and violent stop and veered slightly into the lane to my right. I was not braking at the time. Rear wheels had locked and vehicle had to be dragged to the shoulder as rear wheels would not turn. There were no indications of any problem at the time of the incident. Vehicle was in drive, and seemed to be operating normally. Vehicle was taken to Toyota of glendora in glendora, CA for service. I was told that the rear differential had leaked out, and it along with the rear tires had been replaced under warranty. This was a new vehicle with less than 4500 miles on it. It had not had its first oil change nor any other service. The problem was not caused by external damage, and it was explained to me by the dealership's service advisor that the part had not been properly sealed. Vehicle has no warning system or dash light to communicate a loss of differential fluid as it would with oil, tire pressure, temperature, etc.
Part inside differential broke and punched hole in differential case. Differential could have locked up at high speed. I was lucky to discover that oil was leaking from the differential before an accident happened. Truck had less than 18,000 miles on odometer.

First incident occured while vehicle was stuck in light snow and ice condition. 4-wheel drive system did not appear to be operating properly. Engaged new "crawl-control" system per owner's manual instructions. During use of crawl-control the motor rpm's exceeded 5,500; immediately pressed engine-stop button and applied brakes. Incident resulted in catastrophic damage of front drive-line. Damage included front drive-shaft failure; dealer indicated "drive-line" replaced. Significant damage to components adjacent to front drive-shaft. Vehicle repaired under warranty. Two days after service random brake lock-up occurs while driving; vehicle skids out of control. No malfunction indicators showing. Abs also does not activate during panic stop brake application. Brake lockup experienced in winter conditions at high elevation nearly causing potentially fatal accident (1,000ft drop from road to canyon bottom, no guard-rails). While driving at 30mph the rear end of the truck begins to slide sideways. Upon coming to a stop it is discovered that the vehicle will not drive forward. Engaged 4-wheel drive and vehicle struggled to move. Engaged differential lock and drove backwards for 80ft. Wheels appear to become un-locked. Drive forward for another 500 yards and same situation occurs.

Oil changed at Toyota dealer, mechanic discovered rear differential leak. Took the vehicle to private mechanic and discovered the rear differential leak was caused by rust to the body. The 2004 Tacoma had only 27,000 original miles which was brought new. Web search discovered 20 complaints at least on the differential rusting thru. Talking to the mechanic reveal this can be a catastrophic event on a highway with the wheels locking up causing fatalities. Toyota dealers contacted provided no help or did not return phone calls.
The contact owns a 2002 Toyota Tacoma. The contact stated that the frame started to deteriorate. The vehicle was taken to a dealer where the technician applied an under coating to the frame. The contact stated that the coating eventually wore off. The vehicle was repaired. The manufacturer was not made aware of the failure. Updated 04/21/lj the consumer stated he made an appointment for the corrosion frame recall. Before the appointment, he noticed a lot of oil droplets on the tail gate of the truck, as he drove off, he noticed a puddle of oil. An inspection revealed, the differential case was leaking and it needed to be replaced because it was extremely rusty. Also, the frame was rusted, and it needed to be replaced. Updated 04/24/14.
The contact owns a 2007 Toyota Tacoma. The contact stated that after having the transmission module replaced, the vehicle exhibited a loud humming sound. The vehicle was taken to an independent mechanic, who stated that the rear differential needed to be rebuilt. The manufacturer was made aware of the failure. The vehicle was not repaired. The VIN was not available. The failure and current mileage was 106,000.

Loud noise coming from the rear end. It appears the differential case rotted out leaving the rear end with no gear fluid. When they replaced the frame (as it rotted out to). . . They shoud have replaced the differential housing. Lucky this happen around town and not on the highway. I can imagine what would have happened if the differential blew apart at high speed (with flying metal and no control of acceleration if needed to avoid or cause an accident). I called Toyota car care and they said they would go in half on the repair and get back to me in a few days with the details. They didn't. . . I called them a few days later and they said they couldn't help me. Looked to be a +/- $2,000 repair.

My 2004 Toyota Tacoma was recalled in 2012. The recall letter stated that in certain states where road salt is used to manage winter driving conditions, the potential existed for premature rust/corrosion of the frame. I brought the truck in to the dealership where it was then determined that the frame should be replaced. Six months later I noticed that the rear differential housing was leaking. Why didn't the recall cover these components, which are located in the same general area and subject to the same corrosive conditions as the frame, leaf springs, control arms, etc. , all of which were replaced? if the fluid drains from the housing as a result of rust/corrosion, the potential exists for the drivetrain to lock up, especially at higher speeds, resulting in an obviously dangerous situation. No real options exist to address the issue aside from replacing the differential housing, a repair that costs several thousand dollars. My complaint is that Toyota chose not to cover the replacement of all parts necessary in order to insure the safe operation of the vehicle in light of the premature rust/corrosion issue, nor did they raise the issue in any way. I cannot imagine how Toyota could be unaware of this condition.

Rust out of the differential cover. All of the oil in the differential leaked out. No parts are available from Toyota. The complete differential must be replaced at a cost of over $ 1,000. 00. This is a major problem as per many Toyota forums on the net. Toyota will not stand by this repair and will not admit to any problem about rust.

Rear differential whines/roars at speeds 50-70 which indicates there is a failed component within. Toyota issued technical service bulletin t-sb-0076-08 for problem. Dealer, john royberts Toyota of manchester, TN, attempted to repair but could not. Now, says all Tacomas have whine/howl, a normal condition. If this is true, then ever Tacoma has a potential problem of differential lockup while driving which could cause deadly accidents.

I have a 2009 Toyota Tacoma and when the vehicle is stopped for example at a red light the vehicle rpm will increase and the vehicle will then lurch forward. Fortunately my foot in on the brake. The vehicle also has a whining noise from the rear of the vehicle that has been identified by Toyota regional reps as a whining noise from the differential at 50 to 70 mph. Taken back 3 times to dealer they say its normal but I know it is not. These may be 2 sperate issues but it is clear that Toyota makes it difficult for is customers to get warranty reapirs and in acknowledging a problem. Toyota should be ashamed for its lack of customer service in fixing its vehicles until people get injured.

2006 Toyota Tacoma with automatic transmission. Same complaint as others. Low end rumbling sound and vibration in front end between 55 and 65 mph. Front differential bearings, where front axles enter the differential case, have excessive play (slop) in the bearings. Dealer refuses to repair the bearings even though it is still under warranty. I have video taped the condition as well as the mileage and will keep records of my multiple visits to the dealer. I have also found other used Tacoma trucks on dealer lots with as little as 20,000 miles that have this same problem. I believe Toyota engineered these differentials to last only 60,000 mi and most owners may not notice the problem until warranty is over. My 1992 Toyota pickup 4x4 with 238,000 miles has less bearing slop in it than the '06.
The contact owns a 2008 Toyota Tacoma. While driving 55 mph the rear differential locked and the vehicle veered to the left and crashed into a ditch. During the crash the left rear wheel came off along with the axle and brakes. The contact was dazed from the crash and passerby notified 911. The contact sustained injuries to the entire right side of his body and was taken to the hospital. The contact stated that the air bags did not deploy. The dealer was informed of the crash and advised the contact that a representative would inspect the vehicle to determine if the damage was covered by the warranty. The inspection has not determined if the vehicle was destroyed or not. The failure mileage was 16,700.
Gas tank shield severely rusted. Under side of gastank is protected by a shield/skid plate. It is rusted so badly that when hit with a hammer the hammer goes right through. Presumably this shield is to protect the gas tank from debris and stones especially if the truck is used off road. I discovered this as I was inspecting the underside of the truck before dropping the truck off at the dealer to have the frame replaced. In addition to this, it is apparent that the drive axle and differential housing also have severe rust. If tapped with a hammer the rust comes of in sheets. The parking brakes actuating levers have rusted in place and can no longer be used. There appears to be more to this rust than simple frame rust. The rust is pervasive through out the underside of the truck.
My problem deals with a 2007, Tacoma, x-cab, prerunner, v6, thats equipped with limited slip differential. The problem is that every time that I parked the vehicle and get back into it, start the vehicle, and releases the parking brakestheres a grabbing feeling/noise in the rear end of the truck. The noise you can hear and feel it, as the vehicle moves out of the parking lot. However, the dealerships service department told me that this is a normal thing that all Toyotas that are equipped with limited slip differential do. In other words, they told me that this is normal and grabbing noise of this vehicle. Its hard for me to believe this; I feel there is a problem with this vehicle in the rear end. When I brought the vehicle in July 2007 (new), there was no grabbing noise/feeling. Why now, almost a year later. Can someone tell me is this normal of having a vehicle equipped with limited slip differential? the noise seems to be getting louder and I am worried that the vehicle goes out of warranty and then the dealership will tell me theres a problem with the rear end. Costing me dollars to repaired. Can someone help me with this issue? this problem has been going on now for least five months or more.
I own a 2006 Toyota Tacoma which I purchased new, and now have 11,347 miles on it. It's an automatic 4 speed ect-I transmission. From date of purchase to present at speeds between 50 and 60 mph there is a loud gera whine. Below 50 and above 60 it goes away. I think it may be caused by the ring & pinion gears in the differential,although I am not certain.
There is a whine in the running gear at 53 to 63 miles per hour. Above or below that speed range there is no whine.
Differential made a bad noise at 21,221 miles checked gear lube only to find it empty. Took it to Toyota city where they said it was fine. Took it to independent repair shop, said obvious leak on pass. Side end of diff, axle. I had 15,000 mile service done at Toyota city ($165. 00), they never checked the diff, gear lube even though the owners maintenance book says to inspect diff, gear lube. (no repairs were even attempted at Toyota city). Brought the missed diff. Fluid check to cust. Service reps attention, said she will talk to service department, a month later, and still no reply .
Truck always pulled to the left since new, took it in to Toyota dealer 4 times, they said nothing is wrong with it. At 21,000 miles I heard a bad noise coming from the differential, I pulled over and removed the fill plug only to find no oil in it. So I put in 4 oz. Short of a quart of 80w90 gear oil. (pulled to left because a wheel bearing wasn't getting and lubrication). Returned to dealer, they said we can't find a leak, 50 miles later I pulled the fill plug and found the oil to be black as can be with metal in it. Dealers answer is to come back when it breaks. So now I am stuck with a 2003 Tacoma with a 200,000 mile differential. (what a shame).
At 21,000 miles heard loud noise for differential, and bad glunk when leaving stop light, Toyota never put in gear lube to cover up the bad welds on right end of differential (that would have leaked if they did put in gear lube), no reply from e-mails, phone calls, talking to cust. Rep, (requested arbitration forms by phone and e-mail 6 times, never received them even though Toyota lied and said they will send them. ) .
Rear differential failed.
