Basic Inspection

Clean all disassembled parts, and check for wear, damage, or any other faults, then repair or replace as necessary.

When disassembling, check inside of gearbox for water. If any water is found, carefully check boot for damage, input shaft dust seal, adjusting screw and boot clips for poor sealing. If faulty, replace with new parts.

2	Dust seal	Crack or damage Wear	If outer wall slips, lip is worn out or damage is found, replace it with new one.
3	Rack and pinion	Poor mating of rack with pinion	Adjust backlash properly.
