When I back up while turning the rear wheels start to bind up. It feels alot like a 4WD with the front hubs locked in and trying to turn on dry pavement although it looks like the rear wheel just can't freely turn. I have a 1972 Chevy PU 4WD with a posi rearend and 3.73 gears. Does anyone have any ideas? :confused:

The clutches in the posi are probably locking up, makes the rear end like it's a solid axle.

Change the lube in the rear end. Use GL-5 & put in a posi. additive.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
