What is the minimum U joint operating angle that manufacturers recommend?
1 DEGREE
RULE 1: UNIVERSAL JOINT OPERATING ANGLES AT EACH END OF A DRIVESHAFT SHOULD ALWAYS BE AT LEAST 1 DEGREE. RULE 2: UNIVERSAL JOINT OPERATING ANGLES ON EACH END OF A DRIVESHAFT SHOULD ALWAYS BE EQUAL WITHIN 1 DE- GREE OF EACH OTHER (ONE HALF DEGREE FOR MOTOR HOMES AND SHAFTS IN FRONT OF TRANSFER CASE OR AUXILIARY DEVICE).
What does a slip yoke eliminator Kit do?
Another benefit of an SYE kit is that it seals the tail shaft at the back of the transfer case, meaning it will not leak fluid if the drive shaft is removed. Slip Yoke Eliminator kits consist of a shorter output shaft, new speedometer ring, output yoke and nut, snap rings, front and rear output seals and a new shorter output case.
Can a slip yoke change the driveline?
Because it is able to slide in and out of the transfer case, the slip yoke can change driveline length even though that drive shaft is fixed. However, once the Jeep is lifted it changes the driveline angle beyond what the slip yoke can cover.
How do you alignment a CV drive shaft?
Place one of the flat edges of the angle finder against the socket. I use the magnetic side as it helps hold things in place. Make sure you have everything lined up squarely and all the components are flat against each other.
Can a constant velocity drive shaft be tightened?
So you have installed your brand new slip yoke eliminator (SYE) on your transfer case and you just finished tightening the bolts on your new double cardan drive shaft (also called a constant velocity or “CV” drive shaft).
Why do you need a slip yoke eliminator?
When you lift your Jeep, the angle of the rear driveshaft increases. This can cause driveline vibrations and premature wear. A Slip Yoke Eliminator or SYE kit for short, reduces the length of the transfer case tail shaft by moving the “slip” function on to the drive shaft and changing to a fixed yoke on the rear of the transfer case.
Can a transfer case be removed from a slip yoke?
Often if you have dropped your transfer case in an effort to minimize angle of the rear shaft, the lowering kit can now be removed due to decreased angularity from both length and the fact that the upper angle is now split between two joints.
Because it is able to slide in and out of the transfer case, the slip yoke can change driveline length even though that drive shaft is fixed. However, once the Jeep is lifted it changes the driveline angle beyond what the slip yoke can cover.
What do I need to replace my slip yoke?
All kits include replacement output shaft, tailhousing, rear seal, bearing, 1310 CV style yoke, hardware, and instructions. There are several areas worth noting on this topic.
