Torsion Bar, Front Driver Side

To remove the Torsion Bar and supports assembly, raise and support the vehicle first. Mark the adjuster bolt and install the Torsion Bar loading/unloading tool (J 36202) to the adjustment arm and the crossmember. Enough to create a hand wrench, tighten it through the adjuster bolt, remember how many turns it takes for further reference. To remove the adjuster bolt and adjuster nut, then remove the Torsion Bar loading/unloading tool (J 36202) so that the Torsion Bar can unload. Shift the Torsion Bar to the front to take off the adjustment arm, then the upper mounting nuts and bolts of the Torsion Bar support link. Then discard bar support from the frame, and the torsion bars, being certain of the forward end and side of the dismissed bars. Replace the lower retaining nuts of the Torsion Bar links and disengage the links from the Torsion Bar support. For installation, affix the Torsion Bar links to Torsion Bar support and install lower retaining nuts tightening to 50 nm (37 ft lbs). Mount the torsion bars in the original places and place the Torsion Bar stand to the frame. Tighten the upper mounting bolts and nuts of the Torsion Bar support link for 65 nm (48 ft. Lbs). Mount the adjustment arm on the Torsion Bar support and push the Torsion Bar rearward till it is fully inside the adjustment arm. Mount the Torsion Bar loading/unloading tool (J 36202) back to the adjustment arm and crossmember, and put tension on the Torsion Bar by turning the adjuster bolt the same number of turns as in the removal. Finally, install the adjuster bolt and adjuster nut, remove the torsionbar loading/unloading tool (J 36202), drop the vehicle, and inspect the wheel alignment.

The vehicle needs to be lifted before it receives support to replace the Torsion Bar and support assembly. Record the location of the adjuster bolt before using the Torsion Bar loading/unloading tool (J 36202) to mount it onto the adjustment arm and crossmember. Make the necessary tension adjustments on the adjustment arm while recording the turn count for future use. After tool removal you can allow the unloading of the Torsion Bar. After moving the Torsion Bar toward the front position the technician removes the adjustment arm before unfastening the upper nuts and bolts on the support link assembly. Disconnect the frontfork and separate the torsion bars while recording which end faces forward and which side is being taken off. You should remove the lower retaining nuts securing the Torsion Bar links then detach the links from the Torsion Bar support. Fasten the Torsion Bar links to their position on the Torsion Bar support and torque the lower retaining nuts to 50 nm (37 ft. Lbs.). Place the torsion bars in their factory installation positions before reattaching the Torsion Bar support to the frame followed by tightening the upper mounting bolts and nuts to 65 nm (48 ft. Lbs.). Reinstall the adjustment arm to the Torsion Bar support by sliding the Torsion Bar backward until complete engagement occurs. Connect the Torsion Bar loading/unloading tool (J 36202) to the adjustment arm and crossmember while increasing the tension to properly load the Torsion Bar. Use the adjuster bolt tightening procedure from removal to achieve the same number of turns before installing the bolt and adjuster nut. Check wheel alignment by lowering the vehicle after tool removal.
