Symptoms
Clunks over bumps, a rear end that steers itself, rusted or seized shackles, or bent lower shock-mount bolts. Comanche Club owners recommend upgrading the rear lower shock mounts.
The fix, step by step
- Support the frame and take the weight off the springs.
- Soak every bolt in penetrant for a few days first.
- Unbolt the shackles and front hangers, drop each spring, press out the old bushings and fit new ones (polyurethane needs grease).
- Fit new shackles, torque everything at ride height, and replace the shocks while you're there.
