Torsion bar adjustment

[Daveb]

Any input on where the adjustment bolts would have been from the fact? I’m asking as a neophyte in torsion bar suspension mostly because I find it odd that both of them are threaded as far out as they can be. Truck sits about an inch lower on the driver side in the front and about a half inch in the rear. Is this something that gets taken care of when an alignment is done?

The Haynes manual has some measurement/specifications for the "Z height" or something like that. Here's a video that explains it: https://www.google.com/search?sca_e...oFHePKDakQ0pQJegQICRAB&biw=1920&bih=945&dpr=1

My 06 Suburban 2500 2wd had the torsion keys "cranked" by the previous owner. I'm not a fan because it looks leveled. I refreshed the front suspension and got it aligned, then remembered I would "undo" the cranking of the keys, but forgot. Doh!

You can probably tweak your keys. There's a special tool the local parts stores rent, in case you need to remove the torsion bars/keys. Not sure if you need that or not in your case?

It needs to be done when aligned.

Now to find a shop around here that has an alignment tech older than the truck

Make sure that the shop does a 4 wheel alignment where the front adjustments are done referencing the rear thrust angle.
