    Note: Vehicles equipped with Meritor RPL Series drivelines do not require periodic lubrication.

  1. If equipped with a grease fitting, wipe all old grease and dirt from the slip joint grease fitting; see Fig., item 1.
    • After grease appears, cover the pressure-relief hole while continuing to lubricate.

  2. Use a hand-type grease gun or a high-pressure gun with a low-pressure adapter, to lubricate the slip joint. Add multipurpose chassis grease (lithium 12-hydroxy stearate, NLGI Grade 2, with EP additives) until it appears at the pressure-relief hole in the yoke plug. Then cover the relief hole with your finger, while continuing to apply gun pressure until new grease appears at the slip joint seal; see Fig.. This ensures complete lubrication of the splines.
  3. Wipe the purged grease from the pressure-relief hole and slip joint seal, and any excess grease from the grease fitting.
