Lubrication the Slip-Joint Spline

rv mm 20.00.000
  1. Check the slip-joints for spline wear by trying to bend the sleeve-yoke and splined shaft back and forth. If looseness is greater than 0.007 inch (0.18 mm), replace both the sleeve-yoke and the splined shaft.
  2. Wipe all old grease and dirt from the slip-joint grease fitting.
  3. Use a hand-type grease gun or a high-pressure gun with a low-pressure adaptor, to lubricate the slip-joint. See Fig.. Using lithium 12-hydroxy stearate grease (NLGI grade 2, with EP additives and meeting ASTM D4950 LB specifications), lubricate until fresh grease appears at the pressure-relief hole in the yoke plug. Then cover the relief hole with your finger, while continuing to lubricate until fresh grease appears at the slip-joint seal. This ensures complete lubrication of the splines.
