DID YOU KNOW... !
Rubicon Express recommends running a rear CV driveshaft on
any Jeep lifted 3.5” or taller. When lifting a vehicle, excessive
compound angles are put on the conventional two joint drive
shaft which creates vibration and possibly premature failure.
Common Causes of Vibration: The two most common
causes of driveshaft vibration are: Driveshaft imbalance and U-Joint
operating Angles. Proper driveshaft geometry is critical.
Improper driveshaft Geometry will create vibration, excessive
wear and premature failure.
Driveshaft Maintenance: Driveshaft inspection should
be performed as part of a regular maintenance routine. We
recommend lubricating the driveshaft at every oil change or
if you’ve been in a large amount on water, whichever comes
first. The lack of proper lubrication is one of the most common
causes of driveline failure especially in the CV ball assembly.
The CV assembly needs to be uninstalled from the transfer
case yoke to properly grease with a needle type fitting for a
grease gun.
Spicer recommends: For any lubricant used on driveshaft
applications, the following is recommended:
•A good quality E.P.-2 (extreme pressure) grease or a compatible
grease meeting N.L.G.I. Grade 2 specifications with a operating
range of +325 degrees F to -10 degrees F.
