Noisy rear diff?

I have a 2011 TRD Sport 4x4 and mine also makes noise when I decelerate at about 70 mph on the highway. Over time the noise has been more noticeable.

 

Check to see it the Rear Diff replacement/fix is for your year / model.

 

Well the dealer got the part in on Monday, and I just got the truck back today.

Problem is solved, and actually there must have been a lot of gear noise that I didn't notice at the time, because the truck seems much quieter at all speeds now.

I am very pleased that Toyota stepped up and replaced the diff, even if it did take over 55 000km of complaining to do so.

 

that's great!

did the dealership mention what was actualy wrong with the diff?

 

No, they didn't really specify.
I had been pressing the issue for a long while, so I didn't want to push my luck when they finally agreed to swap in a new one.
This is the invoice, but it doesn't reveal much.
