I recently bought an 03 Tacoma 4x4. Long story short, my neighbor had it from new, and due the all too common undercarriage rust issues, the rear diff housing rusted through and he ran it out of oil. Found a guy in Jersey selling a complete rear axle housing assembly with 3rd member, e locker actuator etc. and bought it for $350. He wasn't sure if the diff was good or not but, for the price I got a rust free complete rear... Installed this and test drove-- Very noisy especially at higher speeds and decelerating. So apparently the diff has issues. Visually I see no bad wear on any of the gears, and no chips or chunks missing, so thinking carrier bearings???. I got a very rough estimate from a shop of $600 to rebuild. This seems expensive to me but i really don't know. I've never rebuild a diff before so wondering if anybody can give me advice on this.. Should I have it rebuild or try to do it myself? Is it very involved? Any special tools required? Where can i get a parts kit..Dealer or aftermarket?
Thanks.
Thanks.
