My torsion bars had been tempered with and you could see that a hex bit that was too short was used before because it was difficult to drive my hex bit all the way in.

When I tried to back off the splined bracket I realized it was stuck on the bar. I then had to make a puller that fit on the hex bit and extension because it had to be pulled while someone was holding the torsion bar tension.

Looking at the splines you can see that they are twisted and tapered.The twist is due to the splined being engaged half way and the taper seems to come from torquing with hex bit not all the way in and probably not the right size too.

Now is there a way to improve the splines on my torsion bars, the bracket will go in only with hydraulic press.
