Best Practices

When replacing a steering gearbox, we recommend using a factory replacement unit. Be sure to verify that the timing and gear ratios are an exact match to the old gearbox.


During any steering gearbox replacement, be sure to inspect all of the steering linkage for excessive play and replace as needed.

If the steering gearbox is power assisted, be sure to flush out the system to remove any dirty fluid and debris. On European vehicles, replace the steering fluid reservoir because it contains a filter that gets clogged after 60,000 miles.

Common Symptoms

When a steering gearbox is failing, the steering effort may increase or become jerky and uneven. The steering linkage may feel loose, have excessive play, and the gearbox may leak fluid from the steering shaft shaft seals or cracks in the steering gearbox itself.

Common Misdiagnoses

Sometimes broken or missing steering gearbox mounting bolts, or loose, worn out steering linkage and/or a cracked frame near the steering gearbox can be confused with the symptoms of a failing steering gearbox.
