New Tundra, whining noise? :(

Thank you! Will definitely check the fluid before driving again! I’m so bummed! We waited almost 4 months for the truck Thanks again!

 

Hi everyone, I think we may have identified the problem. There’s a thin metal piece right behind the universal joint and before the rear differential that is not secured and is spinning. They think it might be a dust cap/seal?? Here’s a pic. Argh

 

Looks like you’re not the only one:

That is so crazy!!!! We finally got our truck back last week. All they said was they got a new part and fixed it, I’m
Thinking it’s that dust cap. It drives great now. Disappointing to hear that we are not the only ones

 

Yes the old dust seal squeal and click. Tacomas and 4runners can have this issue as well. This is usually found after hard off roading and from an impact.

 

Do you have work order to see what was replaced?
