RepairPal Certified shops can diagnose and repair your 2004 Chevrolet S10. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
You'll have to call local salvage yard for price.. Gear ratio will have to match, salvage yard should have info... Has a 'mechanic' confirmed differential is SHOT?.. Was that estimate for repair of existing rear axle?.. Do you know what happened to it, ie..ran without lube, bearings or gear problems?
