3901 Torsion Bar Indexing...

Message

   So I guess I'll start with why this needs to be done and seeing as how a picture is worth a thousand words.... 

The first thing to do after jacking up the truck and putting jack stands under it is to mark you arm and frame with a sharpie to let you know your starting point.
Then move the rubber boot back so you can access the c-clip.

Here's a shot of the clip. I was able to get it off with a couple screwdrivers.

Anyone know where I can source these boots new? Mine are dead...

After you pull the c-clip tap the arm back with a hammer until it pops loose. At this point, if your arms are still in good shape you can rotate the arm and reinsert the torsion rod one spline up.

I hate speed mountains

Here's a shot of the whole deal on the floor...

All bent back into shape...gotta love steel 

Final clearance. I gained about an inch rotating it one spline. I don't think I'll be ripping that bolt out anymore 

All in all it took about 20 minutes and that was mostly cause I used scissor jacks....

	Looks good Redeye. I did mine after Bleach posted pics of how he did his & yeah only took about 30 minutes. I had 1 of the torsions come out from the arm like your pic shows, the other only the piece that you hammer came off. It's a quick fix for clearence problems for sure. Thanks for the pics.

	just remove the anchor bolts then remove the nut on the A arm up front almost off then pound it out w/o hurting the threads me and Icehouse did his 521 truck. We NEVER removed the c clip from the back we just pulled the torsion bar from the front A arm and reindexed it there. Had to jack up the wheel to get it to reinstall. We never wanted to take the c clip out.

	Yeah after Bleach posted up I had to try it out, I was tired of fixing that in parking lots lol. The c-clip came off easy. I pretty much pushed it most of the way off with a couple screwdrivers and then popped it out with one of the screwdrivers...It's smaller than the c-clips holding my axle stubs on my jeep. Pulling the shaft was a breeze as well. Hopefully these pic's will help out the next guy who needs to take care of his torsion arms

	Redeye, pics really do help alot. Its easy sometimes to "tell" somebody how to do a mod or fix something but with a pic it makes it easier. Thanks again.
