Replacing Torsion Bar Mounts on a GMC Syclone

This article is visible to only you.

The stock torsion bar mounts wear out over time and need to be replaced. It's a pretty simple procedure and will reduce the annoying clunks you hear when going over speed bumps and similar road hazards.

The truck will clunk under your feet when driving over speed bumps and other objects.

Jack Up The Truck

1

Place wheel chalks behind the rear wheels and apply the parking brake.

2

Jack up the front of the truck till the front wheels are off the ground. Place jack stands on both sides of the truck.

3

Mark the ride height adjustment bolt before removing so that you will have the same ride height after re-assembly.

4

Remove the ride height adjustment bolts in each torsion bar pork chop.

5

Remove the top nut that secures the torsion bar mount to the crossmember.

6

Place a jack under the crossmember on the same side. Raise the jack until the crossmember lifts high enough to remove the torsion bar mount.

Remove the last two bolts that secure the mount to the frame.

8

Remove the torsion bar mounts from the truck. They are asymmetrical, so note the orientation of the stud/indent on the top of the mount.
