What 1999 Jeep Wrangler owners say
Most recent owner complaints, unedited.
I started hearing a banging/clanging noise under the rear of this vehicle upon starting/stopping or reversing. The noise is best described as a sharp metallic clang. Undercar inspection revealed the frame has corroded to the point the upper control arm mounts have pulled away from the frame and the track bar that locates the axle side-to-side has separated from the rear axle housing along with the upper control arm mount separating from the axle housing. Repair of this vehicle requires replacement of the frame along with replacement of the complete rear suspension and axle housing. This same vehicle was reported to you 03 november 2016 for the same issue involving the center section of the frame rusting through causing the transfer case mount/skid plate to drop. Safety caps were installed on the frame at this time and the vehicle was placed back into service.
Frame rotted from rust where the rear suspension attaches to the frame. Too much rust to repair. Remaining vehicle is in good shape considering only 107k miles. Suspension broke free from the frame during normal road operation. I am told that the problem is epidemic with jeep tj frames. Apparently so because there is noting available on the used parts market. Lots of tj bodies and parts available but no frames to go along with them.
Jeep is a 5 speed transmission. Couldn't shift correctly, heard a rattle. Engine had fallen due to rusting frame. Frame so rusted, engine fell. Only 90,000 miles on vehicle. Not driven daily. Was in motion.

Jeep wrangler (tj body) 1999 frame rust I was driving the vehicle at interstate (68-72mph) speeds when a severe vibration started suddenly and the manual transmission shift lever dropped to a lower than normal position. I pulled off in a safe area and inspected first for a flat tire and then looked under the vehicle. I noted the right frame rail had rusted through from the inside and the transmission-transfer case mount/skid plate ass'y had separated from the right (passenger side frame rail and dropped approx. 2-3 inches. This caused severe driveline vibration and erratic vehicle control.
