A NEW VERSION OF THIS GUIDE IS NOW AVAILABLE
A new and revised version of the 9-5 rear suspension guide is now available. This old document is still valid, but it's recommended that you use the updated version.

The rear suspension upgrade performed on a 1995 Saab 9-5 2.3t. I was installing Aero springs and shocks from the roadholding kit.

Car on jack stands

The car is secured on jack stands.

Spring bracket

The wheel is off. The spring bracket is attached with four 16 mm bolts. We need to remove the lower bolts and slacken (but not remove) the top ones.
17.06.2004
Lower bolt

The next step is to remove the lower retaining bolt (21 mm)...

Strut assembly

...and the assembly falls down. Note how incredibly rusty the top nut is. It is a 16 mm nut when new, but with all this rust I could only fit a 17 mm socket on it.

Rusty nuts

Both shocks removed, the nuts are now soaking in WD-40. The rods have a 7 mm hex head on the end, but with this much rust it would be very hard to remove the nuts with just regular tools.
17.06.2004
Impact tool

An impact or air wrench would be helpful, but I don't have either. Instead, I've got the best impact tool ever -- a hammer! The shiny wrench is thin enough to hold the hex end of the rod through the hole in the black socket. Insert a spare bolt into the side hole of the socket, whack it a couple of times -- and the nut moves!

Spring compressor

The spring has to be compressed to disassemble the damper safely.

Victory!

A few more minutes of cleaning the threads with a wire brush, and the nut comes off.

Old vs new

The Aero dampers and springs are 10 mm shorter the regular ones. The spring appears to have the same coil thickness, but it is definitely stiffer.
17.06.2004
New vs old

The kit comes with a complete set of washers and bushings. Note the zinc spacer ring at the bottom -- my old shocks had it melted a long time ago.

Work in progress

The old parts are on the floor, and I'm ready to install the new ones. For those who asked again: NO, the car DOES NOT stand on these concrete blocks.

Spring closeup

A correctly installed spring should fit in the recess of the spacer ring.

Retainer nut

The new retainer nut is a beauty! Not too tight, just 15 ft-lbs.
17.06.2004
Baloon

This pink birthday baloon will hopefully keep the moisture away. I would really like to see the face of the next person to take these shocks apart ;)
17.06.2004
Aligning the holes

After the spring bracket is fit with the top two bolts, we need to align the hole of the lower retaining bolt.
17.06.2004
Hydraulic wrench

140 ft-lbs of torque is not the kind of power I can boast while cramped under the car, so I'm using the jack on my torque wrench.
17.06.2004
Spring bracket

The four spring bracket nuts need to be tightened at 40 ft-lbs.
