Count and record the number of exposed threads on the track rod, from the end of the rod to the track rod end locknut. Remove the track rod end on the side concerned by unscrewing the locknut from the track rod. Release the two clips and peel off the gaiter. Clean out any dirt and grit from the inner end of the track rod and, when accessible, the rack. Wrap insulating tape around the track rod threads to protect the new gaiter during installation. Refit the track rod end locknut, positioning it so that the same number of threads counted on removal are visible, and then refit the track rod end.
