DIFFERENTIAL

2000 GMC Jimmy

Other Category problem
2000 GMC Jimmy 6 cyl Four Wheel Drive Automatic 80000 miles

Loud moises from rear end, mechanic tells me it is the differential and has given me a price to rebuild, $800, but said that the outside is all rusty and has recommended that I replace it with a used one. He has not opend the unit up as of yet to inspect. This vehical was driven in NY for 5 years before relocation to NC. Is there an issue with rust on the outside of the differential? Would you recommend a new used or rebuild the existing?

I just replaced my rear it was cheaper for me I got a used one which was what I could afford but u can find a good cheap rear end that might be better than the old one mine had 170k mile sthe one I bought has like 60k miles and newer for half price to rebuild the gears.
