Grinding/Scraping/Groaning Noise From Rear Suspension (Replace Spring Tip Pad)

Some customers may comment on a grinding/scraping/groaning type noise coming from the rear suspension area that is audible in the passenger compartment. This condition typically occurs on high mileage vehicles that have been operated in areas exhibiting high levels of grit or sand contamination. The noise is most apparent when the vehicle is operated over irregular road surfaces or during quick starting or braking maneuvers.

The wearing away or complete/partial detachment of the rubber tip pads on the rear transverse composite leaf spring may result in the unprotected spring end sliding on the cast knuckle surface.

Replace worn or missing rear spring rubber tip pads with those contained in spring tip service kit, P/N 10432057, using adhesive, P/N 10432060. Follow the applicable service procedure in the Rear Suspension sub-section of the Service Manual and those contained in the service kit.

Notice: If the bare ends of the spring (tip pads removed) exhibit significant wear or gouging greater than 3 mm (1/8 in) in depth, then the spring is damaged beyond repair and replacement is required.
