rear differential whining

welcome to the forum!

 

There's been a tsb for that for ages now

 

months ago.

 

I have a fix... mud tires

 

Nope. Owners are still whining despite the the fix Toyota has.

 

a lift and Dakars. the TSB did next to nothing for me

 

The whine tsb is the same fix as tsb for leafspring noise. Just rubber spacers added between leaf springs that do nothing for the rear diff. Toyota is way off from correcting the diff whine.
I’m getting rid of my truck, It doesn’t feel like any Toyota.

 

265/75/16 or larger tires fixes the whining. I had it and then ditched the stock tires for 265/75/16's and the whine went away. I'm now on 35's and 4.88's and still no whine.

Toyota fucked up with the 265/70/16 tires.

 

I had the TSB done... no change. I put in Icon leaf springs and no more noise

 

its not. Its an entirely new set of leafs, an insulation pad in the back seat, new cab mount dampers. It helped a lot with mine. Still there but much more faint. My dealer tried to get away with just the squeaky spring pad TSB too since its a much simpler job for them.

 

Ok that you

 

Because the tsb didn't fix mine. It's worse than it was before the TSB.

 

I would say your regear would have fixed it otherwise

Have you opened a case yet with Toyota Customer Service? If not, please do.

Tel: 800-331-4331

 

I’m not sure if it’s related, but there was a recall for the rear differential gasket or rubber thing the replaced on mine.

 

Regear happened long after the bigger tires

 

I had the TSB done about 3 weeks ago. Have since put about 1000miles on it and my noise is significantly improved. Only howls slightly at 60 to 62

 

They got me. I am bringing it to the original dealer to get it right.
Fred Anderson Toyota actually gave my truck back with mega-scratched leaf spring clasps and dented rear tailgate after installing the pads. It took a week for the body shop to paint the spring clasps and fix the rear end.
