Inspection of the Driveline

rv mm 41.02.000

Before lubricating the driveline U-joints and slip-joints, make the following checks.

  1. Check that the yoke-strap capscrews are tightened 50 to 60 lbf·ft (68 to 81 N·m).

    2. Notice: Do not overtighten the yoke-strap capscrews, due to the extreme load occurring at high-speed rotation. A loose or broken capscrew at any point in the driveline weakens the driveline connection, which could eventually result in serious vehicle damage.

  2. 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.
  3. Check the driveshaft for missing balance weights, and for debris buildup. Remove any buildup. If any balance weights are missing, remove the driveshaft and have it balanced. For instructions, see of the vehicle Workshop Manual, or take the vehicle to an authorized Freightliner dealer.
  4. Check that the yoke plug is not loose or missing. Replace the yoke plug if needed. If the yoke plug is missing, the splined shaft may be hitting the yoke plug and knocking it out; check the driveshaft for proper length.
