According to the service manual. Torque bolts at 80 ft lb. Put a jack under the rear end so that the vehicle weight in on the suspension.

Definitely make sure you torque them with a load on the suspension. If you don't, the bushings won't pivot correctly and will wear out prematurely.

You have to torque RUBBER bushings with the axle at normal ride height.

Polyurethane bushings can be torqued with the suspension in any position.

Yet another reason to use Poly.

Yeah, as long as you don't mind suspension that doesn't work.

Although I HATE poly, he is correct, only rubber bushings must be torqued in the loaded position to prevent preload.
