Four problems related to front suspension control arm have been reported for the 1997 Jeep Wrangler. The most recently reported issues are listed below.
The rear of the frame can rust through due to lack of drain holes to let water and debris out causing the rear control arms to separate from the frame.
Driving down the road the rear upper control arm brackets separated from the frame as a result of the frame corroding from the inside out. This caused the rear brake line to brake draining the master cylinder.
Frame was rotted through from control arm towards the back of the vehicle. The vehicle braking ability became difficult and hard to steer.
The frame is rotting away, the frame rot clearly started many years ago. The rust is quite bad and will not stop. In an accident, the body could possibly fly off the frame possibly being fatal. The frame is rusting from control arm brackets to body mounts all of which can lead to very dangerous situations.
