Condition
Some customers may comment on a rattle or squeak type noise coming from the front of the vehicle.
Cause
The front shock absorber plastic pilot ring may be wearing out, causing the shock to misalign in the insulator.
Correction
DO NOT replace the shock. Replace the lower portion, P/N 15834275 , of the upper insulator assembly using the procedure listed below. This
new insulator has a taller plastic pilot ring that is attached to the metal sleeve to aid in the proper alignment of the insulators.
1.
Remove the front shock absorber. Refer to the Shock Absorber Replacement procedure in the Front Suspension sub-section of the Service Manual.
2.
Remove the lower portion of the upper insulator from the shock and discard.
3.
Install the new lower portion of the upper insulator to the shock.
Important:
Be sure to center the shock in the frame bracket and tighten the upper mounting nut when the vehicle is on the ground.
4.
Install the front shock absorber. Refer to the Shock Absorber Replacement procedure in the Front Suspension sub-section of the Service Manual.
