The following areas of the frame should be checked before performing a steering gear frame liner repair.
If there are cracks in these areas of the frame, the frame must be replaced. Inspect the mounting surface of the steering gear for signs of motion, loose rivets or cracks. Removal of the steering gear may be necessary to check for cracks in the frame liner. Refer to Section 11-02C for procedure. If the frame liner is cracked or has loose rivets, repair the liner by using Frame Repair Kit E6TZ-5K130-A. If necessary, a steering gear line-to-frame rivet repair can be made by using the following procedures.
