Raise the car and secure it on jack stands. Take the wheels off. Both wheels
need to be in the air so the suspension is level.
Detach the anti-roll bar link from the trailing arm.
Unscrew the bracket supporting the brake line and handbrake cable.
There should be no tension in the handbrake, so don't forget to release
it when you raise the car.
The Saab Workshop Manual does not mention unbolting the shock, but I
found that it allows for more freedom to move the arm around. Use a big
breaker bar to loosen this bolt.
Support the trailing arm with a jack so it won't strain the brake line
when you unbolt it from the car.
Undo three 18 mm bolts holding the bushing housing to the car. Carefully
lower the jack, support the brake line separately.
Before taking on the bolt that goes through the bushing, clamp the housing
to the trailing arm. This will make it easier to loosen the nut.
Pull the bolt out and slide the housing off the bushing. The housing is
tied to the handbrake cable, just let it hang off it.
Push the rubber part of the bushing out using a gear puller or another suitable
Assemble the hacksaw with a blade inside the bushing and cut through the
soft aluminium sleeve.
Chisel the sleeve out and discard the old bushing. Clean the inside of the
hole and all the contact surfaces.
New polyurethane bushing from Powerflex. Comes with a stainless inner
sleeve and a bag of grease.
Lubricate the bushing, slide in the polyurethane halves first, then the
Fit the housing, clamp it to the arm and tighten the nut to 70 ft-lbs
Lift the trailing arm using a jack until the bushing enters its socket
on the underside on the car.
Position the housing as close to the original location as possible and
tighten the bolts to 66 ft-lbs +30°.
Re-attach the brake line bracket. These thin M6 screws broke off on both
sides when I took them out, so I had to re-drill and tap the holes again.
Put the screws on anti-seize.
Tighten the anti-roll bar link bolt to 40 ft-lbs. Re-fit the lower shock
bolt if you unbolted it (140 ft-lbs). Tighten the wheels to 81 ft-lbs and
lower the car to the ground.
