To bookend my previous front suspension rebuild series, here is another video series covering the rear suspension. These 5 videos cover the complete process from start to finish, all my screw ups, and some lessons learned.

Part 1: Teardown

Removing the brakes, axles, and trailing arms.

Part 2: Remaining Teardown

Removing the spring plates and torsion bars.

Part 3: Torsion Springs + Spring Plates Install

Installing Elephant Racing polybronze bushings, hollow torsion bars, and adjustable spring plates.

Part 4: Trailing Arms, Hubs, and Parking Brakes Install

Installing rear trailing arms, wheel hubs, and rebuilding the parking brake assemblies.

Part 5: Brakes, Axles, and Rear Shocks

Putting the rear brakes, axle shafts, and rear shocks back on.

As usual, I did make some aftermarket upgrades (polybronze and poly bushings, hollow torsion bars, adjustable spring plates, adjustable Koni shocks), but the rebuild steps are nearly the same for a 100% stock rebuild. I wont be covering my suspension alignment until I have it dialed in and can speak to the process effectively.

I hope this series takes some of the fear out of rebuilding your suspension. It’s a ton of work, but you can do it!
