Hello everyone, was wondering if I can get some help diagnosing an issue I've been hearing for about a couple weeks so far.

I'm getting a whining noise from the rear end of my 03 TB, it has the 4.10 locker rear end. The sound get's louder as I accelerate, especially on the highway. I will be checking fluid in the rear diff tonight when I get home.

Any thoughts?

Thanks
Larry

Checked the fluid it's fine, do you think it might be a bearing?

Bueller Bueller?

Oops, can this thread be moved to 02-09 4.2 specs

Thanks!!!
