Rack-Piston & Worm: Inspection

Clean and dry all parts. Inspect worm and rack-piston grooves for scoring. Inspect ball bearings for damage.

NOTE: If either worm or rack-piston are damaged, both must be replaced as a matched set. If any ball bearings are damaged, replace entire set.

Check ball guides for pinching at ends. Inspect lower thrust bearing races for cracking, scoring or pitting.
