Differential Unit Problems of Toyota FJ Cruiser

From acceleration; between 30mph and 45mph my vehicle shudders and shakes. I believe the issue is coming from the transmission and or differential of my vehicle.

Takata recall- rear differential went bad, no hard driving, and changing fluid frequently.

Went to gas station today to fill up my fj with gas and the fuel tank straps broke in 2 places. The bolted and pinned connections are still there but the actual straps have deteriorated and snapped right in half. The fuel tank is now hanging down completely in the rear. First the rear differential manufacturer's defect which they would not pay for at all, now the front seat belt does not work at all and now the fuel tank is about to fall off on the road. What a hazard.

Read differential has failed. Years affected are 2007-2009. In 2010 Toyota issued an updated stronger version of the differential. When differential fails it can lock up both wheels at high speeds thus losing control. There are over 2000 complaints online and over 10000 complaints with Toyota alone. It is not only costly it is very dangerous. Mine broke at 40 mph and I ended up in a ditch. What if I had been doing 60 or 70.

At mild acceleration and only when between 1,000-2,000 rpm the vehicle starts to shake / rumble from the rear similar to driving over rumble strips. The rumbling stops as soon as the accelerator is let go of or as soon as the vehicle's rpm falls outside of the 1,000-2,000 range. It is obvious that this is coming from the rear differential assembly. Toyota is well aware of this problem but refuses to provide a fix even though this is clearly an issue of defect in design or build. Our government should protect the taxpayer on this one and force Toyota to enact a recall.

The contact owns a 2007 Toyota Fj Cruiser. While driving 60 mph, an unknown grinding noise was heard from the rear of the vehicle. The failure occurred whenever the vehicle was operated. The vehicle was taken to the dealer where it was diagnosed that the rear differential failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 79,000.

Replaced rear differential $2,500, was advised when picking up the car the frame has rotted out. Mechanic advises life of vehicle approximately 2 years. We would have never repaired the vehicle had we known. I have been advised this is a known Toyota problem.

Rear differential failure. Gear whine/ grind noise getting louder on rear differential. Gear backlash increase. Apparently Toyota is aware of substandard ring and pinion gears in early Fj Cruisers and changed the design in later models. Vehicle has never been subjected to off road conditions. Fear gear is going to break and leave me stranded somewhere, so need to replace assembly. Toyota should recall these early differentials as the problem is well documented on all the fj forum sites.

Noise from rear of vehicle progressively worsened over 3-4 weeks. Extreme whine/hum with wheel rotation with corresponding decreased gas mileage. Took to dealership and was told that the rear bearings were "shot" and the rear differentials needed to be replaced. I have completed all regularly scheduled maintenance the entire almost 9 years that I've owned the vehicle and have never had any issues. Estimated cost for dealership to repair is ~$2000. Car has 115,000 miles. Wouldn't expect an expense of this magnitude when all maintenance has been completed by dealership.

Vehicle has loud humming or whining noise coming from the rear end of the vehicle. Noise starts around 25 mph and continues to get louder the faster the vehicle goes. Problem didn't begin until around 120500. Notified dealership and they stated that there wasn't anything that could be done other than replace the rear differential and bearings.

This is a complaint upon Toyota and as they have been aware of manufactured defect in the rear differential gears and bearings of most if not all 2007 Fj Cruisers. All that are made in 2006 for sale in 2007 have or will have a differential go out as it is a "2000 dollar time bomb waiting to happen as the Toyota service manager stated" I asked the manager if any assistance has been given to any of these repairs as it is a common problem with all 07's and he said Toyota just assisted one they did a few months back and it was out of warranty. With this information it seemed it could be a possibility since Toyota is very aware of the manfucatured defect of the rear differential. So I left the Toyota dealership and made my call right away as to just be fustrated as they stated they could not assist in anyway other than file a claim. Still the case even after mentioning that Toyota assisted in paying for some of the cost of this defective part replacement of another same year not that long ago and still got a big no way can we help in anyway with costs as it is not a safety hazard, but to me it could be a safety hazard as I have heard that the rear differential can go out and no powertrain at all at any given moment and could in the middle of an intersection turning, up a hill, passing another vehicle, pulling a trailer, etc. My differential cover is also starting to get hot and smell from I imagine friction. Anyhow so many incidents of the same case with the same year and same problem, its hard to say how many really complaints and clains theyt have gotten. I have been told more than a thousand cases. Please take this serious and Toyota needs to own up to it for allowing a time bomb waiting to happen and some of those customers had it happen as soon as 65,000 miles just out of warranty. Many others experience the same problem even at earlier mileage just out of warranty.

The contact owns a 2007 Toyota Fj Cruiser. The contact stated that while driving at approximately 60 mph, there was an abnormal grinding noise coming from the rear of the vehicle. The failure recurred multiple times. The vehicle was taken to a dealer where it was diagnosed that the rear differential and both rear bearings needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 125,000.

I was driving on a surface street and felt a strange but and then a distinct thump, thump,thump, sound began emitting from the rear of the vehicle, I contacted my local Toyota deal but they failed to provide me with any helpful information regarding any recalls regarding the rear differential. Since I had the vehicle at a shop already and it was out of warranty, I allowed an outside shop to do the work. 1ea ring and pinion gear set, 1ea bearings kit, 1ea seals kit, synthetic oil, and labor for a total of $2002. 20 I find it hard to believe a vehicle with 41. 000 miles on would have it rear differential fail in the manner that this unit failed.

Head a slight grinding sound sound coming from the rear of the car(2007 Fj Cruiser with 56k miles) took it in to have it inspected and was told it was the rear differential. Bearings in the rear diff needed to be replaced and the job would cost estimated 1700 dollars to fix. Really bummed to hear that as I dont drive aggressive with this car or drive it off road at all. Keep reading other people have the same issue with this car year and Toyota has not done a recall? I always tell people to buy Toyotas because they are reliable, not a happy camper at all. The company need to do the right thing and recall something known to be bad!.

Rear differential failure. This is a common problem in the early year models of this vehicle. Starts with loud whining from rear of car followed by complete failure of gears inside rear differential.

The Fj Cruiser I purchased in 2007 was quite reliable until recently and it seems that this is a serious defect with the machined differential in early builds of this model. Toyota will not take responsibility for this defective differential for some reason although there have been over 1000 cases so far posted on the internet specifically related to the carbon brittlely in the differentials that are failing. .

Heard noise coming from back of car. Sounded like it could be the brakes. Took it to Toyota, was told it was the rear differential. My husband is a quadriplegic and we have a lift on the back of our car. Need it for his scooter. Car only had a little over 80,000 miles on it. Have always bought Toyota. . . No one will help. Won't even meet me half way. Not the dealer, not the people I wrote to at Toyota, no one. This is not right. I have even gone online and found many others with the same complaint. Will anyone listen? it is in the shop right now and we are having it repaired for just over $1,600 dollars.

Severe rust issues. Entire rear differential required replacement. All power steering and automatic transmission lines needed replacement, fuel lines are next fuel tank straps rusted and broke off, tank fell down. Brake pad pins required cutting off. Protection plates rusted off. Exhaust system components required replacement due to rust. Entire frame and engine compartment covered in rust. All these items have caused multiple safety issues. Multiple straps and connections for various components are no longer usable due to rust.
