Installation Notes
• Install the tie rod by reversing the order of removal.
• Before installing the tie rod assembly, verify that the
ball joint tapers and the mating tapered surfaces in
the steering arms are free of burrs, dirt, and debris.
DO NOT apply lubricant of any kind to these
surfaces.
• Verify that the tie rod clamps do not make contact
with anything when steering in either direction.
Reposition the clamps as needed.
• Tighten castle nuts (4 and 6) to 30 lb-ft (41 N·m).
Adjust (tighten) nuts as needed to align the slots with
the hole in the rod ends.
• Always install new cotter pins (3 and 7).
• Adjust tie rod. (See “Tie Rod Adjustment” on
page 7-4.)
It is important that all components are absolutely
clean, as contamination can result in serious
damage and/or improper operation.
Never use shop towels or rags to dry parts after
cleaning, as lint may clog passages. Dry parts
using compressed air.
