Failure Date: 02/13/2013

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.

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.

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.

Failure Date: 07/20/2010

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.

Failure Date: 06/10/2010

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 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.

Failure Date: 12/28/2009

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.

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. ) .
