TROUBLESHOOTING

REAR DRIVELINE:

Acceleration vibration:

Caused by the pinion being too high in relation to

the transfer case output shaft. Adjust pinion angle accordingly with

optional cam bolts.

Deceleration vibration:

Caused by the pinion being too low in relation to

the transfer case output shaft. Adjust pinion angle accordingly with

optional cam bolts.

Slip yoke vibration:

Caused by excessive angle on the transfer case slip

yoke - common on vehicles with lifts. This can usually be cured on 1.5”-

3.5” lifts with a transfer case drop kit or adjustable cam bolts - see

acceleration and deceleration vibration troubleshooting above. Adjustable

cam bolts (RE1475) allow some adjustment of pinion angle.

HIGH SPEED WOBBLE:

This is fairly common with y-type steering on lifted TJ's. 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. A good

rule of thumb is minimum factory caster and maximum factory toe in.

Note that lift heights increased with coil spacers (or taller coils) may

exhibit wobble that cannot be corrected with alignment.

BUMP STEER:

Caused by improper relationship of drag link and track bar. To correct,

center axle again following the instructions supplied with the track bar

next determine the neutral position of the steering wheel. Adjust the

drag link to center the steering wheel.
