PST v. QA1 strut rods

72bluNblu - glad you replied! When I was trying to figure out what to do I found your posts extremely helpful! Thanks! You are spot on re: PST install - you just cut out the old rods (assuming like me you can’t get the nuts off) and install the PSTs without disconnecting the torsion bars to move the LCAs back. Ease of install was the primary reason I went with PST. And it was pretty easy. I did not find the adjustment to be cumbersome, but maybe that’s because I did it wrong (?). I tightened the rear bolt and checked for binding and was pretty close to the positive caster I was looking for, then was able to make final adjustment by loosening jam nut and turning the rod without loosening the rear bolt.

Just make sure you re-torque the rear bolt. If you were able to adjust the length of the rod without loosening the rear bolt it means one of a couple things happened. The whole assembly may have rotated, which would mean the rear bolt isn’t tight enough. Or the adjustment you made was small enough that you didn’t see the small gap that opened up between the strut rod body and LCA. Or the best case, the bolt was a little loose and your adjustment served to tighten it.

Just check the torque on the bolt, and if you have to tighten it significantly re-check for binding.

It’s not a huge difference, I have both styles of adjustable strut rods. The QA1’s are a little easier to adjust, but the PST’s are easier to install on an already assembled suspension.
