944 Rear Suspension — Tightening Torques

Factory tightening torques for the 944 rear axle and axle shaft — trailing-arm wheel-hub nut (steel and aluminium arms), axle shaft, brake backplate, caliper and wheel fasteners — plus the note on the standardised running-gear mount tuning from 1991. Torques switch between N·m and ft·lb.

The factory tightening torques for the 944 rear axle and axle shaft. For the front-axle figures see front-suspension torques and for the alignment that goes with this work see wheel alignment. Torques switch between N·m and ft·lb.

Standardised running-gear mount tuning (1991 onward)

From the 1991 model year the rubber-metal running-gear mounts were standardised on the 944 S2. The earlier "hard" versions (944 Turbo and 944 S2 with M030) and the "soft" version (standard 944 S2) were resolved into one ideal tuning state, affecting both the front and rear axle. The spring-strut mounts and stabiliser are the soft version; on the running gear the transverse-tube thrust mount and rear-axle trailing-arm flanbloc are the hard version, with the control-arm flanbloc and mounts, support mount and rubber mount bearing flange the soft version. Take this revision into account during repair work.

The sensor air gap is a design feature and is not set on the car; bleeding follows the same procedure as a car without ABS.
