95 chevy G20 rear differential
 

you sure it isnt the tires?

ok, well there should be the option codes on a sticker in the glove box?

Car-Part.com--Used Auto Parts Market Nationwide search engine for junkyards. Found a dozen listed in my state alone. The search engine will filter out parts that are not compatible so you'll only get parts from / for similar vehicles.

Your van has a noise at the rear and Sears managed to tell you the same thing? :rolleyes: Ya might want to take it to a reputable, local shop that exists for repairs (& not tire sales). If it was a rear differential problem, Sears would likely farm it out for repair anyhow... and charge you the farmed rate + $.

Confirm the noise source & ask the local 4wd guys who they use to set up their gears & you can usually find a shop who knows their way around a rear end. You can rebuild anything in the rear axles unless it's been badly damaged (Been jumping any stumps? :D ).

Did they pull the rear cover? Could be a pinion nut loose, pinion crush that's sloppy, a bad axle bearing or heck - dragging emergency brakes. Not a lotta details here. What's it doing? Why do you think it's the differential or axles & not the brakes? Tires were mentioned above... any odd wear patterns or bare spots? Have you put it up on jackstands (secured) & ran it to trace the noise? Any wobble in the rear tires?
