Post subject:  torsion bars

My grandsons 72 scamp broke the torsion bar on the drivers side. Is it advisable to try and find a pair and change both at the same time. Also I was told it takes some special tools to do this. If this is the case we would probably need to take it to a specialists who works on suspension. any help appreciated. Also should we try and find new or used bars.

I would replace them as a matched set, to keep the spring rates and ages the same. Check the boots and replace the clips while you're at it.
If you're only going to replace the torsion bar, the only truly special tool you'll need would be the torsion bar tool. It simply clamps onto the bar (withouth scratching it) and gives you a place to push/hammer. There are commercial versions, or you can make one using U-bolts and a beefy chunk of angle iron. I think some have even used wood blocks, clamped and drilled together, then bolted around the bar. Other tools would be a good jack and better stands, a ratchet and socket for the adjusters, pliers for the clips, hammer, and your favorite break-it-loose juice. I like PB Blaster. What am I forgetting?
I took my suspension apart without the torsion bar tool, but I removed the lower control arm with it for a bushing replacement. I had to use balljoint and tie-rod end separaters.

If he broke one side, cut the other in half with an angle grinder then just slide evrything out no need for the tool, the tool is so you do not knick or cut the metal which can cause weakening. Do not forget to take all the tension off the torsion bar/lower arm, one bolt, easy to do.

Just make sure you take the dinky c-clips off and replace the baloon seals if cracked and torn (as mentioned earlier).

Mancini racing has great prices on torsion bars. Mopar performance still selss them. Go for the .89 or .92's. I just upgraded to the 340 swinger bars (.87?) and would like them a little stiffer.
