Normal Operation

The EPAS gear is very susceptible to water, moisture, dust, rust and other contaminants. If a damaged boot is suspected the inner tie rods and steering rack should be inspected for water ingress, corrosion and contamination. If water ingress, corrosion or contamination is found a new EPAS gear should be installed.

New bellows boots and clamps must be installed whenever they are removed. To avoid unnecessary repairs address all other known concerns, DTCs and customer concerns before removing the bellows boots and inspecting the steering gear.

1. K1: INSPECT THE INNER TIE RODS AND STEERING RACK FOR CORROSION 
   NOTE: When installing new bellows boots and clamps, apply new lubricant as instructed to prevent water contamination and follow all installation instructions or damage may result to the steering gear. For complete information refer to the Tie Rod Removal and Installation procedure in the Power Steering article.
   • Remove both outer tie rods and bellows boots. Refer to the Power Steering article.
   • The following inspection must be carried out on BOTH sides of the steering rack:
     • Turn the steering wheel in one direction all the way until it stops to expose the steering rack.
     • Inspect the rack, inner tie rod and gear housing for rust, moisture, corrosion and other signs of harmful contamination.
   • Is the rack, inner tie rod and gear housing free of moisture, rust, corrosion and other harmful contamination?
