I have a Chevelle 12 bolt posi with 373 gears in it. I put new bearings , races. and new clutches in the posi differential. I shimmed the clutch packs up as tight as I could. Now the car is hard to push. It will spin both sides all the time. Should I take the posi back out and put more clearance in the clutch packs? :? The gears are quiet going down the road. I apologize I meant to put this in drive train :oops:
