95 yukon torsion bar problem?

[youknowmyname67]

Ok so I am new here and I couldnt find a post that really answered my question so here goes.... I have a 95' yukon 5.7L 4x4 and i know the drivers side usually isnt level to the passenger side but in my case my driver side frame from front to back (measured in 3 different spots, front middle and rear) is 1" lower then the passenger side. I measured with the vehicle empty on level ground. I could not find any broken leafs and this is a noticeable lean when looking from the rear.... I made sure my tires were all at the same psi all the tread is worn evenly (same depth on all tires etc) i replaced the shocks so my question is could the torsion bars be off..... I just bought the car about 4 days ago and i am unsure if maybe they had a lift on it they took off and just didnt even out the torsion bars etc.... Also I am uncertain if the torsion bars only lift the body of it they will lift the frame also.... either way I am looking for some help and advice as to get this fixed.... i have new bilstein shocks on it like i said tires are all the same with tread depth psi and size....measured fron of frame middle of frame and rear frame all points are 1" lower then the passenger side...... any help would be appreciated.

yes its very possible the torsion bar is causing sag. basically the torsion bar is twisted and put in a bind creating a force, this force causes the lower control arm to push down more. while lifting the vehicle it also stiffens the ride and changes the geometry of the front suspension. they are similar to leaf springs in a way that they flex more so then usual from age. to fix the sag simply tighten the bolt on the torsion key a 1/4 turn at a time, drive around the block to allow the suspension to settle, measure and repeat if necessary...hope this helps

Is this only for the front? or will it do the front and rear? also does it only lift the body or does it lift the frame?

torsion bars are only in front and it does the frame not body.

Dope! A double posting.

I found the other one and replied already. Then I found this one...
My suggestion is that you only need one thread.....
Just my $0.02.

There's good info in both threads though...
