Torsion bar removal - Hardbody Nissan Cars & Trucks

The procedure is the same on every vehicle that uses this type of opening assist. So here is another persons instructions on a GM product.
Tools used:
Leather gloves!!
3/4" combo wrench (biggest I had)
1/2" deep socket (3/8")
6" extension (3/8")

1.With the trunk lid up and the curved part of the torsion bar against the rear trunk wall, I slipped the box end of the combo wrench around the torsion bar. I don't remember which way I had the angle of the box end facing. Just use what will work.

2.Then use the extension and the socket on the end of the torsion bar and push back so that you can get the combo wrench down past the curve, this is key. Once that is done you can remove the socket and extension. Pressure will push the wrench against the rear trunk wall.

3.Now comes the fun part. Push the wrench forward (VERY CAREFULLY) all the way past the side engine grill support and onto the peg of the hinge. The tip of my torsion bar just nicked the grill support. Make sure the wrench is seated well because it could slip around on you and cause your paint some damage and maybe even you.

4.Now that the torsion bar is on the hinge peg, you'll notice that your left with a wrench stuck on the bar... Just move (wiggle, twist) the wrench as far to the end of the torsion bar as it will go.

5.Take the extension, without the socket and place over the tip of the torsion bar. Push down while you slip the wrench past the peg. Remove the extension and slip off the wrench.

6.Now use the extension again to push down and put the roller (plastic, metal) bearing onto the peg.

7.Secure all the bolts, and lube it up.

That's it. Hope it'll help someone else. Please be careful.

jack the vehicle right up so that the the wheels are clear of the floor . Place vehicle on jack stands
release the tension on the torsion bar by removing the adjuster in the arm. you may have to use Stiltons or pipe wrench to get the last bit of tension out of the bar . remove and retainers and tap the bar out of the splines.of the lower control arm. mark the bar so that you will know which spline to use for reassembly
remove the lower control arm.

when adjusting torsion bar suspension ,the secret is to jack the car completely off the floor so that the wheels hang down. This removes the load on the adjusting bolt

Autozone.com has some good 'how to's' if you check there.

No, your Honda does not have "torsion bars". You have a coil springs to absorb bumps and give the suspension compliance. A torsion bar was used on many Chrysler products and older vehicles. You may be confusing "torsion" bars with "sway" bars. A sway bar links suspension from side to side to keep the vehicle "flatter" in corners as an aid to handling.

if its the old torsion bar suspension then lift vehicle and block it up the remove the end off the torsion bar and move it around a spline or two but you may just need new torsion bars as it is 19yrs old so its sell by date might have expired a slighty

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.

No the torsion bar if you look at it where it goes to the under carriage it will have a bolt for tension on each side. Are you tring to replace the bushings for the torsion bar? If so answer back.

The torsion bar itself does not have to be indexed,it can be installed in any way,but the end that contains the adjuster has to be positioned in the correct way to attain full adjustment,and correct ride height.The best way to do this is to look and study carefully before removal,so that everything is reinstalled as it was.If that wasn't done in the beginning before removal,it's still ok as the torsion bars can be removed and replaced,trial and error style,until it's right.The thing that changes where the ride height is,is WHERE the adjuster end is,when the torsion bar is fitted to it.I have a 73 Plymouth with torsion bars,so i know what you are going through.Just position both adjuster ends about level when engaging the torsion bars into them.They should slip in relatively easy unless rusted up badly.It is ok to use some grease too,to allow easier install.Their is also a tool available that grasps the torsion bar to assist in removal or install.After install,make sure to replace the retainer clips back in to secure the bars.
