#53 of 1497 Help me level off my front end...Pls 2003 2500HD LS 4x4 by harvestmooon Jan 04, 2003 (6:07 am)
Hi, Im most familiar with solid front axles and have heard I can leveloff my front end by turning up the torsion bars. Anyone that could walk me thru it I would be thankful! Ive searched old posts and there is mention of it many times but no telling how to do it. Is an inch possible this way without damaging anything? Obviously, Id need to realign. J

I've never done it myself, but heard the procedure described here many times; inboard at the rear end of the torsion bar you'll find the adjusting bolt (18mm socket). Crank it clock wise (looking up at it) 4 to 5 full turns, which should raise the front of the truck the inch you're looking for. Alignment? Definetly. My alignment man advised me to be sure to have the truck re-aligned whenever the torsion bars are changed that much. Also, on a level surface, before you start, you might measure at the frame to be sure it's the same height both sides; recently, when having my truck re-aligned, the technician found the factory setting on the driver's side to be 3/4 in. low. Some suggest driving it a bit to settle it in and then re-measure, although I'm not sure it's necessary.

#56 of 1497 J -- Crank your by minikin Jan 07, 2003 (7:10 pm)
bars up 4-5 full rounds; pretty common solution to "level out" trucks that are not normally run with heavy loads. Conventional wisdom aside, re-alignment is not required; you can change front end height pretty much at will within this range with no noticeable camber effect. But an awful lot of GM trucks seem to deliver with out of spec front ends; so if you haven't had yours checked by a good independent shop I would highly recommend it, whether you fool with the bars or not. Might want to also spec castor to the high side to cut down on wander. -- Don
#57 of 1497 Alignment after torsion crank. by gator36 Jan 07, 2003 (9:24 pm)
No matter what you say,when you are raising the front end by adjusting the torsion bars, you completely change the front end geometry.   Per GM's TSB SMU - Revised Front Caster and Camber Adjustment Procedure #02-03-07-002 - (10/04/2002)   Caster measurements or values must be compensated for the measured frame angle.   Caster is relative to frame. The caster values must be compensated for the measured frame angle by using a digital protractor or equivalent on a flat portion of the frame in front of the rear tire.   This is only a portion of the whole proceedure.
#58 of 1497 Another note on front end alignment. by gator36 Jan 07, 2003 (9:26 pm)
Brought my truck to the dealer for a front end alignment. The dealer had a brand new alignment rack. After adjusting the truck to specs, the truck still pulled. The tech was inclined enough to take it to another rack and re-do the alignment. Sure enough it was a ways off...   No substitute for a concientious tech.
#59 of 1497 Leveling results by harvestmooon Jan 17, 2003 (10:26 am)
Thanks to those who helped ! 6 full turns leveled the front end and raised it exactly 1 1/2 inches. Truck looks ALOT better. Had it realigned to be safe. No noticeable difference in ride quality at all. There is actually quite a bit of room for adjustment with the torsion bars and plenty left if I needed it. First I went w/ turns- came up 1/2 inch. Then 2 more-up another 1/2, then last two complete turns brought it up a final 1/2. Its pretty clear that with my truck each turn raised the frame 1/4 inch. I jacked the frame which made turning the bolt very easy. I have the snow plow prep package on my truck which is supose to include stiffer bars. Next, 285's. Ill let you know, looks like plenty of room now, well see. J. 2003 2500HD Chevy

minikin, Not sure I follow your train of thought. Conventional wisdom aside, re-alignment is not required Sure, not required. Nothing is required, but it is sure alot better for the front tires. When you change the geometry, as gator stated, you change the alignment, what do you think you do when you align it? You change the geometry of the suspension.
