Steering Gear Replacement TRW Ross-FH4

Caution: Replace the steering gear mounting bolts, the washers and the nuts every time you remove the steering gear from the vehicle. Failure to replace the bolts, the washers and the nuts may cause the steering gear to separate from the vehicle. This could cause a loss of steering control and personal injury.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
