Condition
Some customers may comment on a "clunk" noise coming from the front of the vehicle.
Correction
Information has shown that the noise may be caused by the following three areas (listed in no particular order). Many of these concerns may initially be
mis-diagnosed as an I-shaft clunk.
^
Body mount at the A-pillar - this noise may be heard mostly during a driving situation in which the body is twisted/flexed (i.e. hitting a pot-hole).
^
Frame - this noise may be heard at the torsion bar crossmember during a turning maneuver.
^
I-Shaft - this noise may be heard when turning at low speeds on rough road surfaces.
