Step 6 - Final details, adjustments and drag link install
A.
Install wheels, verify all coils are properly seated shocks installed and lower the vehicle.
B.
Check the front track bar for axle center, adjust as necessary.
C.
Tighten all control arm and track bar rubber bushing hardware. Use factory specs where factory bolts are used.
D.
Properly bleed brake lines per factory manual and check for leaks and a firm pedal.
E.
Manually disable the factory ESP system before the first test drive. (Refer to owners manual for the disable procedure) Note the
location of steering wheel while driving in a straight line and any driveline vibrations.
F.
Install RE2610 drag link. See supplied instruction sheet for the front drag link (RE2610) for proper install (4.5” lifts only). Adjust
drag link to center the steering wheel. NOTE: Centering the steering wheel is highly critical for proper ESP function. Minimum
factory caster and maximum factory toe-in seems to work well with these front ends (see Troubleshooting as well).
G.
Adjust upper control arms if necessary for proper front castor angle and rear pinion angle. NOTE: Shown below is a diagram of
proper pinion angle for a CV style drive shaft (see Troubleshooting as well).
H.
Retighten all bolts after 50 miles and again after every off road excursion.
I.
After all adjustments have been made, Rubicon Express recommends that your local Jeep dealership “flash” the computer to
adjust for proper tire size and ESP control settings. .
TROUBLESHOOTING
Rear driveline:
Acceleration vibration: Caused by the pinion being too high in relation to the transfer case output shaft. Adjust upper control arm to lower
pinion accordingly.
Deceleration vibration: Caused by the pinion being too low in relation to the transfer case output shaft. Adjust upper control arm to raise
pinion accordingly.
High speed wobble:
It is a condition where front tires will shimmy after hitting a bump. Avoid bias ply tires and wheels with excessive offset. Check for worn or
loose parts. In most cases a reduction of positive castor will eliminate this condition.
