Yesterday, I started mocking up my rear strut assemblies. I thought I had purchased all the new hardware I would need to avoid dismantling the old, rusty assemblies. Quickly, I realized that I had forgotten to order the dust boots and bump stops. Doh!
On a Canadian car this old, there is no way the top shock nut is going to come off. I tried one just to be optimistic. Heated it with a torch, doused the rod in oil…and proceeded to just snap the top of the rod off with my hex bit. Time to bust out the spring compressors and the angle grinder. Here's how that process panned out.
Finally, some process. I got the first rear strut fully assembled…but then I realized that I installed the isolator bushings in the wrong orientation (cone pointing towards the centre of the mount plate instead of pointing away from it).
After taking them apart and correcting the isolator installation, I laid out the pieces to assemble the driver's side rear suspension. This is the point where I realized I have an ugly collection of colours…oh well. They should work nicely.
Since I was running short on time and also running out of daylight, I didn't really take any more pictures. I managed to get both rear trailing arm assemblies back in the car last night. The general process I followed was:
1. Install compensator arms in the trailing arm first (loosely).
2. Bolt the trailing arm up to the chassis (again, leave the bolts a touch loose).
3. Start the bolt connecting the compensator arm to the chassis (I centred the toe sliders and tack welded them in place since I have adjustable arms now).
4. Bolt the lower control arm to the chassis.
5. Push the strut up into the strut tower, swing the lower control arm up into place, start the bolt connecting the strut to the control arm and then start the bolt connecting the control arm to the trailing arm.
6. Place a jack under the lower control arm to lift the trailing arm up into place and hold the strut plate to the strut tower.
7. Install the upper control arm loosely.
8. Install the nuts securing the strut mount plate to the strut tower.
9. Jack up the lower control arm further until the car just starts to lift off the jackstand. This way, I know the suspension is fully loaded.
10. Torque all fasteners to specs in the service manual. I started with the trailing arm bolts, then the upper control arm-to-chassis bolts, then the strut mounts and, finally, all the pivoting joints.
Here's a nasty picture in the dark. I find that the flash makes rust look so much worse than it really is. I'll take better ones in the daylight today.
