Inspect splines of slip joint for wear.
The nylon-coated spline should be free from nicks and dings and the underlying steel spline should not be visible.

After cleaning the nylon coating spline, the coating should exhibit only slight indication of wear.

Grease volume is approximately 10 grams of grease in total. Grease should be evenly applied to both the female and the male slip splines using a small brush. After assembly of the slip joint, the sliding joint should be fully worked from the full collapsed to the full extended position.
Aluminum tube type only: Inspect the aluminum tubing for surface scratches and dents. These scratches may not exceed 0.2 mm (0.008 in) in depth.

Aluminum tube type only: Visually inspect the circle welds and fittings for any signs of cracks or signs of deterioration. If there are any cracks that exceed 0.2 mm (0.008 in) in depth, the assembly must be replaced.
Aluminum tube type only: Check to be sure there are no missing balance weights. If balance weights are missing and void has occurred in the aluminum tubing greater than 0.2 mm (0.008 in), the assembly must be replaced.
