When you tighten the torsion bar you will cause the spring rate to change on the front suspension which means it will bounce a bit more, in theory. Also you will cause the top of you tire to tilt out since the upper and lower a arms are not exactly equal, so you may need a front end alignment too. I've adjusted both a 1992 and 2001 3/4 ton and never had any issue. Cheapest way to level the front end up.
Under vehicle by end of torsion bar (side closer to rear of vehicle) there should be a 6-point bolt which when tightened or loosened will apply more or less tension to torsion bar.
jack up front end, drop both bolts out of the torsion keys, knock both bars out then put new keys in
Jack up the front end. Take out the huge bolts on either side of the truck underneigh both doors. Using a hammer tap the torsion bar of out the torsion bar key. Put the torsion bar into the key, tighten the big bolt to the exact height as it was installed previously.I highly recommend getting a full alignment afterwords.
The 1st generation Nissan Pathfinder, 1987 - 1995 had a torsion bar suspension on the front end of the vehicle. There is a driver's side and passenger's side torsion bar and they are not interchangeable. 1996 - 2009 models do not use a torsion bar.
Take the truck to your local Chevy dealer and have them adjust the torsion bars to lift the front and then do a realignment. About 100 bucks. New torsion bar keys are not needed.
You need a torsion key.. most mechanics can twist the bar for cheap
A torsion bar is used in an auto suspension. A torsion bar suspension, also known as a torsion spring suspension or torsion beam suspension, is a general term for any vehicle suspension that uses a torsion bar as its main weight bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process.
the torsion bar is actually a rod which is twisted when load is applied on opposite direction like couple
Vehicle does not have torsion bars
To change the torsion bar on an Iveco Daily you need to pick up the frame and take off the suspension. At the end you will see the torsion bar which can be rotated and removed. Then. a new bar can go in its place.
There is a bolt near rear of torsion bar (the end closer to rear bumper) which will increase or decrease the tension on torsion bar when you adjust bolt.
Under vehicle, by end of torsion bar not attached to control arm.
