Frequently Asked Questions

Universal Joints: Using a grease gun, pump grease into the universal joint until fresh grease can be seen coming out of all four seals. If all four seals do not purge fresh grease, move the driveline to free up the bearings caps and try again until successful.

Slip Yoke & Stub Shaft Assemblies: Coat both the slip yoke and stub shaft thoroughly prior to assembly, and then fully collapse the driveline. Apply grease via the grease fitting until grease begins to come out of the welch plug vent hole. After grease appears in the vent hole, cover it and continue to grease until it begins to show grease in the seal. During re-lubrication it may not be possible to fully collapse the driveshaft. Use the same greasing guidelines as used during initial assembly but be careful not to overfill the driveshaft. Overfilling the driveshaft with grease may cause the welch plug to pop out during use.

Centering Kits: Using a needle nose grease gun, pump grease into the flush mount zerk fitting on the centering kits until fresh grease appears at the ball seal or purge hole. Failure to maintain grease in centering kits can cause failure very rapidly. Worn centering kits will squeak, indicating that greasing is necessary immediately.
