One problem related to sway bar has been reported for the 1998 Mitsubishi Montero. The most recently reported issues are listed below.
While making a right or left consumer would hear noise for the front of the vehicle. Dealer has been contacted. Please at purchase, a slight churp was noticed, front right. It was checked, but not corrected. Afterwards, noise increased steadily. A front right brake was fixed, but continued to rattle. Sway bar/ bushings were repaired. Also steering became loose. However, churping continued. Diagnosis by a localmechanic claimed that churping and rattling was due to a defective sway bar link and peeling top bushing. But mitshibishi dealers disagreed with the diagnosis, and persuaded consumer to leave vehicle as it is.
