Three problems related to suspension torsion bar have been reported for the 1998 Nissan Frontier. The most recently reported issues are listed below.
There was a sway bar link that was felled in front suspension. When this happened there was a lot of vibration,and rattling when going over bumps.
Front torsion bar linkage bushings do not have washers on top to retain them in place. This allows the bushing to be shoved over the top of the retaining nut resulting in the total failure of the bushing.
Front sway bar link failed. Mjs.
