2012 Tacoma Double Cab 4wd

3 inch Lift

Forgive me if this issue has been hashed over and over, but I've tried the search engine and I get 2000 threads with Bicycles and Superchargers.

I've got a 2012 Taco 4WD Double Cab Base, not sure what package it has the stickers were all peeled off before I bought it. The driver door Vin Info says the diff is an A04C which I believe makes it a 3.73:1 ratio.

The rear diff is beginning to growl. When driving it sounds a little like brakes are wearing out. took the wheels and drums off and used my stethoscope to listen. It seems to be coming from the pinion bearing area. Removing/rebuilding is an option. I will probably buy a rebuilt 3rd member and install it.

Does anyone know a company in the extended Austin, TX (Houston, Dallas, San Antonio) area that sells rebuilt/exchange 3rd members.

Thanks
Rod
