Prepare to Install Front Suspension
1. If there are factory skid plates installed, remove them.
2. Measure torsion bar adjusting screw depth and record this dimension for later use when
replacing the torsion adjuster arm on reassembly. Remove the torsion bar adjusting
screw. Apply a small amount of lubrication grease to the puller threads and the puller
shaft-to-adjuster arm contact point. Load puller and torsion adjuster arm until the
adjuster nut can be removed from the cross member. Release the puller to unload the
torsion bar. With the bar unloaded, slide it forward into the lower control arm until the
adjuster arm falls free. If the bar seems stuck, use a hammer and punch through the
hole in the rear of the cross member to dislodge it. Repeat this procedure on the other
side of the vehicle.
3. Remove the torsion bar cross member by removing the through bolts on each side of
the vehicle. With the cross member out of the way, the torsion bars can be pulled from
the lower control arms and removed. Mark the torsion bars as to their orientation (left
side, right side, and front). They must be reinstalled exactly as removed! Save these
nuts and bolts for reuse on reassembly.
4. Disconnect the ABS sensor wire and position it out of the way to prevent damage to the
wiring or connector ends. Remove brake caliper assembly and securely fasten it away
from the work area.
Important Note

2004 models with traction control and Borg Warner transfer case 4482 may require
Trailmaster driveshaft 51257.
NOTE
Please note that while every effort is made to ensure that the installation of your Trailmaster lift kit is a
positive experience, variations in construction and assembly in the vehicle manufacturing process will
virtually ensure that some parts may seem difficult to install. Additionally, the current trend in manufac-
turing of vehicles results in a frame that is highly flexible and may shift slightly on disassembly prior to
installation. The use of pry bars and tapered punches for alignment is considered normal and usually
does not indicate a faulty product. However, if you are uncertain about some aspect of the installation
process, please feel free to call our tech support department at the number listed on the cover page. We
do not recommend that you modify the Trailmaster parts in any way as this will void any warranty ex-
pressed or implied by the Trailmaster Suspension company.
