Condition

Some customers may comment on a rear leaf spring slap or clunk noise. This noise is most apparent when the vehicle is operated over irregular road surfaces.

Correction

Verify that the rear leaf spring inserts (1) are present on the leading and trailing ends of the overload spring (second stage leaf). The insert may have broken apart from wear and fallen out. If the inserts are not present, install new ones.

Important: On some models, the vehicle may have to be raised to allow the springs to separate enough so the insert can be installed.

Parts Information

Important: Technicians should refer to the Parts Catalog when ordering the insert.
