New gaiter retaining clips should be used on refitting. Begin by removing the relevant track rod end. If not already done, unscrew the track rod end locknut from the end of the track rod. Mark the correct fitted position of the 
Rack And Pinion Boot on the track rod, then release the boot securing clips and slide the boot from the steering gear and off the end of the track rod. Thoroughly clean the track rod and the steering gear housing using fine abrasive paper to polish off any corrosion, burrs, or sharp edges that might damage the new boot sealing lips on installation. Scrape off all the grease from the old boot and apply it to the track rod inner balljoint, using fresh grease if there is any doubt about contamination. Carefully slide the new boot onto the track rod and locate it on the steering gear housing, aligning the outer edge of the boot with the mark made on the track rod prior to removal, then secure it in position with new retaining clips. Screw the track rod end locknut onto the end of the track rod and refit the track rod end.
