Open the full vehicle complaint log (all categories)The Front differential need to be replaced. The dealership where we purchased the vehicle replaced the differential. When we got the vehicle back we still had the same problem. The car was making a groaning sound while turning to the right above 35 mph. And the whole car would shake and my wife said it felt like the car was going to fall apart. The vehicle also needed new sway bar bushings my guess is that is because the shaking caused by the bad differential. A car shaking that bad and the axle loose inside the differential seems like a huge safety issue. Also I found a tsb online for this exact issue. I found that our vehicles vin was part of the tsb. I sent that information to the technician that has been working with us and he was unaware of the tsb. And was upset that he replaced the front differential and was not made aware of the tsb from Toyota. For some reason he couldn’t see it I believe he said it was because the dealership is in the process of changing there computer systems. But from my understanding the tsb is just to put a damper in the differential so you can no longer hear the noise coming from the differential. This in my opinion is not fixing the problem with the differential the axle will still be loose inside the differential causing the vehicle to shake and probably wear out suspension components and tires. We also had 3 different sets of tires installed on our vehicle because of the issue with the differential. When we would take the car to the dealership they said that everything looked good and would tell us that if the car was shaking we should take it back to les Schwab and have them balance the wheels and it never seemed to fix the problem. In my opinion this poses safety issues if the axle fails while driving. Especially in our situation because we live in the mountains where we have many roads that don’t have guardrails and because a lot of the roads were we live are in canyons that fallow rivers and creeks.
