torsion bar

[jakes900]

I'm trying to level my truck out because my front is sagging a little. Couple of questions here. First haynes calls out a spec of no more than 1/4 clearence between torsion bar and support; when you tighten your torsion bar up does it shrink due to tension creating gap. Second mine is about a 5/8 gap is my torsion rod worn out? The adjuster bolt has about 1/4 of thread remaining.

Thanks

Torque them in a bit more to bring up the front end up.

Everyone I talk to tells me to replace the torsion bar mounts. how would that help me gain height? Also is it normal for the adjuster bolts to be very hard to turn. I am a pretty big guy and i'm putting a lot of force on them.

Did you jack up the front end first

The only time I have ever adjusted the torsion arms is on my '93. The process can be tedious. The front end must be suspended off the ground while adjusting. The adjusting bolt is a square head. I used a Mitchell's Motor manual and it gives a height adjustment from a point on the frame to ground, it was 6.22 inches. Turning the adjuster in will give more height. After an adjustment is made, it is necessary to lower the vehicle and roll it so that the suspension will settle in. I'm sure you can see the tedious part of this.

The torsion mounts are important in that they mount the back part of the arm so that all movement will be on the A arm. If they are bad, you need to replace them first.

I actually have a 1994 gmc jimmy 4x4 but their seems to be more info in the blazer section. I feel reallly stupid now, I just crawled under my truck and started cranking on the adjuster bolts. I can see how lifting the whole front end wounld make it EASY seeing as your not trying to lift your truck up by turning just one bolt. Do you think I hurt anything?

How do you know when the torsion bars are bad? Does anyone have any idea how many inches your height should change going from the bolt all the way out to all the way in?
thanks

Hope you matched each side turn for turn.

[jakes900]

I leveled it by measuring from center of front hub to top of hood each side.

[BlazerLT]

No, you equally crank down each bolt the same amount of turns.

I have a plow on my 96 2dr and the front was sagging probably from carrying the extra weight in the winter time. I turned each Torsion adjuster 3 full turns and that raised my front 1" as measured from center cap of rim to fender lip. It sits nice and level now. Most torsion bar people I talk to will adjust them as they sag and not replace them until on breaks.
