SERVICE INFORMATION

This bulletin contains Parts Information and Service Procedures to rebuild a leaking steering gear from the Applied Models.



DIAGNOSING THE LEAKAGE Leaks from the steering gear can be external or internal. External leaks occur at fittings, on hoses, or through porosity in the steering gear housing. Internal leaks occur through seals inside the gear and result in fluid leaks at the steering gear boots, the pinion input shaft, or retainer.



Before attempting to rebuild a Maxima steering gear, determine the type of gear installed in the vehicle. Maximas built before December, 1985 have a different design gear that requires a different rebuild kit and procedure. Steering gears from these models should be rebuilt using Technical Bulletin ST86-005 (TS86-103).

The later design gear can be distinguished quickly by examination. The later design does not have a separate aluminum cylinder end housing and has wire boot clamps instead of metal band clamps.



REBUILD PARTS INFORMATION

The steering gear must be completely disassembled and inspected to determine if the gear can be rebuilt and what parts are required. Use the flow chart below as a guide for the inspection sequence and part numbers.
The rebuild seal kit contains the following parts. Those parts that have an indicated part number are also available separately.
