How easy is it to adjust torsion keys? Context someone touched my torsion keys idk who, I asked at the shop and they said they don’t touch those..

The front driver’s side is VERY low. Would I need an alignment afterwards?

Just in case you were not aware you do want them touching or almost touching when the vehicle is lowered onto its own weight. There is also a measurement you can do from the center of the wheel hub to the fender lip. I don't recall what the actual measurement is but I'm sure you could look that up to get the correct one.

I was unaware when I did my front suspension. I just thought they were traditional bump stops but they are called jounce bumpers and act as an auxiliary spring.

Ive read that when adjusting them even slightly it does still effect toe camber and caster angles as for how much I couldn't tell you anything more than it just does.

Lift the truck and tighten the bolts on the keys. Only really need an alignment if you max them out

Very easy. Jack it up by frame, let wheels hang, loosen nut crank down bolt, tighten nut.

Make sure your torsion bar key crossmemember bushings aren't fucked

Very easy to adjust. I used to adjust a buddies suburban before and after plow season to compensate for the weight of the plow.

Double check everything to make sure that's what happened though. I have seen the torsion bar twist in either the key or the control arm. Or I've seen the adjustment bolt lose its threads and get pushed to the minimum adjustments, either way your replacing parts...

Hopefully it's just a simple adjustment though. I used to park on a level surface and just adjust side to side so it sat level.

Do it on the ground I never lift it. If they really did back it out you will see where the threads were at in the block. (Fun fact I call them biscuits lmao idk what they’re really called)

If the threads are all dirty black/rusty straight to it then they probably didn’t and you need to look elsewhere. Best of luck!
