Question about 1998 GMC Safari

Recently had new idler arms installed along with new shocks all around. Van now seems unstable...sways. Could torsion bars need adjusting?

    Thanks, I did get an alignment done (the steering wheel was way off)....mostly the 'toe' had to be adjusted. However the 'swaying' is still pretty bad.....hence my thinking that torsion bars need to be adjusted. Do they not have adjustable screws that tightens or loosens the tension?

    When I drive over some dips in the road...tends to keep swaying instead of the shocks absorbing the initial movements..keeps going...they are new shocks. At higher speeds...gets worse and feels more unstable..sometimes white knuckle. When they put in the idler arms

When you change the two idler arms did you have the front end aligned? It could be possible that the alignment is off. If you are having to put alot of input to the steering wheel while driving that may give you the sway feeling you are describing. The torsion bars control front ride height and should be checked as part of the alignment. Hope this helps.

    Does it sway when driving or when you are turning around a corner. Yes you are correct about the torsion bar adjustment it has a bolt for adjusting. It is possible that the alignment could still be off. The toe for all wheel drive should be about zero.

    It is possible that the shocks that were put on your van are to soft and could cause the concern over dips. Did the van do the same with the old shocks? I would return to the repair shop and tell them you feel it is unsafe to drive after the repairs. Hope this helps.

Can up country shocks be used on a non-up country suspension. Worried about the travel and collapsed measurements. Not enough travel or too little?


doubtful the shocks would be the source of any creaking/squeaks. Most creaking and squeak noises are usually a result of worn/dry bushings. I would inspect all swaybar/control arm bushings for dryness and deteriation. Spraying wd40 on all rubber bushings in the rear may cause the noise to subside for a while until you are able to isolate the exactr source

How do i remove yhe lower control arm on a 2008 Nissan Frontier 3.0l turbo diesel?


You need to loosen the torsion bar adjusting bolts until all the tension is removed, remember to mark a reference point from bar to frame so you can get close to the correct riding height after reassembly. Can't tell if you split the ball joint from the knuckle from your explanation but a couple of good solid whacks to the lower knuckle will unlock it. Mark & remove the control arm bushing bolts and use a pry bar to push out arm @ bushings.

My Front left tire is tilted inward and underneath the truck i found one of the support bars that run's across is broken off on the left side. I looked around the wheel and found that no metal was bent so...


General Description
The front suspension allows each wheel to compensate for changes in the road surface without affecting the opposite wheel. Each wheel independently connects to the frame with a steering knuckle, ball joint assemblies, and upper and lower control arms.
The control arms specifically allow the steering knuckles to move in a three-dimensional arc. Two tie rods connect to steering arms on the knuckles and an intermediate rod. These operate the front wheels.
The two-wheel drive vehicles have coil chassis springs. These springs are mounted between the spring housings on the frame and the lower control arms. Double, direct acting shock absorbers are inside the coil springs. The coil springs attach to the lower control arms and offer ride control.
The upper part of each shock absorber extends through the upper control arm frame bracket. This bracket has two grommets, two grommet retainers, and a nut.
A spring stabilizer shaft controls the side roll of the front suspension. This shaft is mounted in rubber bushings that are held by brackets to the frame side rails. The ends of the stabilizer shaft connect to the lower control arms with link bolts. Rubber grommets isolate these link bolts. Rubber bushings attach the upper control arm to a cross shaft. Frame brackets bolt the cross shaft.
A ball joint assembly is riveted to the outer end of the upper control arm. A rubber spring in the control arm assures that the ball seats properly in the socket. A castellated nut and a cotter pin join the steering knuckle to the upper ball joint.
The inner ends of the lower control arm have pressed-in bushings. The bolts pass through the bushings and join the arm to the frame. The lower ball joint assembly is a press fit in the lower control arm and attaches to the steering knuckle with a castellated nut and a cotter pin.
Ball socket assemblies have rubber grease seals. These seals prevent entry of moisture and dirt and damage to the bearing surfaces.
Four-wheel drive models have a front suspension that consists of the control arms, a stabilizer bar, a shock absorber, and right and left torsion bars. The torsion bars replace the conventional coil springs. The lower control arm attaches to the front end of the torsion bar. The rear end of the torsion bar mounts on an adjustable arm at the crossmember. This arm adjustment controls the vehicle trim height.
Two-wheel drive vehicles have tapered roller sheel bearings. These bearings are adjustible and need lubrication.
Four-wheel drive models and RWD Utilities have sealed front-wheel bearings. These bearings are pre-adjusted and need no lubrication.
Heat treatment may create darkened areas on the bearing assembly. This discoloration does not signal a need for replacement.
Hope this helps?

What is the torson bar on jimmy and where can you get the part for it?


1995-2005 Models NOTE: The following procedure requires the use of the torsion bar unloader tool No. J-36202 or equivalent.
  1. Raise and safely support the vehicle.
  2. Remove the transmission shield, if equipped.
  3. Install a torsion bar unloader tool to relax the tension on the torsion bar adjusting arm screw; record the number of turns necessary to properly install the tool. Remove the adjusting screw and the unloader tool.
  4. Unfasten the lower link mount nut from one side, then disengage the torsion bars. NOTE: Note the direction of the forward end and side of the torsion bar being removed
  5. Remove the lower link nut from the opposite side.
  6. Remove the lower link mount, upper link mount nut, upper link mount and then unfasten the torsion bar from the frame.
To Install:
  1. Install the torsion bar and support.
  2. Install the upper link mount and mount nut.
    • Tighten the nut to 33 ft. lbs. (45 Nm) on 1995-96 models and 48 ft. lbs. (65 Nm) on 1997 and later models.
  3. Place a jack under the torsion bar to release tension, then install the lower link mount bushing and nut.
    • Tighten the nut to 13 ft. lbs. (18 Nm) on 1995 models, 50 ft. lbs. (68 Nm) on 1996-98 models and 37 ft. lbs. (50 Nm) on 1999 and later models.
  4. Install the torsion bar unloader tool and tighten the tool against the adjusting arm the same number turns recorded earlier, then remove the tool. This loads the torsion bars.
  5. Install the transmission shield, if removed.
  6. Remove the jackstands and lower the vehicle.
  7. Check and adjust the Z height as outlined in the wheel alignment portion of this section.

you could try replacing the shock absorbers, use a stiffer/firmer shock. ( check out "bilstein" shocks). inspect the sway bars, look at the rubber mounts, make sure they are still in good condition. Or maybe install a aftermarket sway bar. also see if you can adjust the ride height of the suspension. I can adjust the ride height on my 89 Mark VII. up or down.
