DRIVELINE TIPS I
TOLERANCES
1. Check for excess tolerances before lubing application. Lube may mask, or hide excessive play and
tolerances.
2. U-Joint maximum end play is .006. More than that will result in failure.
3. Slip movement, up and down, maximum allowance is .017. More than that will result in
failure.
4. Dents, missing weights, dirt and foreign material buildup on shaft, can cause vibration and balance
issues, resulting in failure that can also cause damage to transmission and axle.
5. Center Bearings, new self aligning style, has gold colored collar, without deflectors. Self align style
became available in 2002 and will allow + / -5° angle deflection.
6. Driveshaft standard slip application has splines that face the power source and end yoke.
7. Driveshaft outboard slip assembly has splines that face toward rear of application.
8. Phasing - mark slip position with paint stripe during disassembly to make sure that you
reassemble in same position and phasing to avoid timing and vibration issues.
9. Lubrication Basic Procedures:
U-joints - make sure that grease purges at all four seals to ensure that old grease does
not contaminate new grease resulting in potential chemical incompatibility.
Slip Splines - 6 to 8 pumps from grease gun is acceptable.
10. Refer to Maintenance Manual MM-96147 on Literature on Demand at meritor.com for
additional information regarding torque specifications and troubleshooting information.
