PROBLEM:

FRONT RADIUS ARM NOISE / CREAK

CAUSE:

Insufficient torque / clamp load on the fixings securing the radius arms to the axle case bracket.

ACTION:

Where a complaint of the above is confirmed, inspect the front radius arm to axle case brackets. If the brackets do not incorporate a welded washer and the nuts and bolts are to the old specification, (see illustration 1) and (‘A’ in illustration 2), the nuts and bolts must be replaced with the new specification flange headed nuts and bolts, (‘B’ in illustration 2).

1. Raise vehicle on lift. 2. Remove nut from radius arm bolt to axle case bracket and remove bolt. 3. Fit new radius arm bolt and nut to axle case bracket, torque to 210 Nm. Caution: Ensure torque does not exceed 230 Nm. 4. Repeat steps 2 - 3 for the remaining fixings. Replace fixings individually.
