What is a slip yoke on a truck?
What is a slip yoke on a truck?
The slip yoke is a vital part of your vehicle’s drive shaft and is what allows the shaft to flex when going over rough, uneven terrain. This flexion gives your drive shaft’s U-joint the ability to continue rotating properly in more demanding conditions.
What does slip yoke eliminator do?
Slip Yoke and Slip Yoke Eliminator This sliding capability allows for changing length depending on the vehicle’s movements. A slip yoke eliminator, abbreviated SYE, does what the name suggests: It eliminates the slip yoke from the transfer case. Instead, it turns it into a fixed yoke that does not slide.
Where is the slip yoke?
The slip yoke is the part of your driveshaft that connects the driveshaft to the output shaft on your transfer case or transmission. The slip yoke seal is the seal that allows that yoke to move in and out while still keeping the transmission or transfer case fluid sealed inside.
What causes slip yoke clunk?
The slip yoke could be the cause of that driveline clunk or bump. Some vehicles with rear-wheel drive and may exhibit a driveline clunk or bump that occurs as the vehicle starts to move forward following a stop. This condition may be caused by the slip yoke not sliding smoothly on the output shaft splines.
Should you grease slip yoke?
If you have a 1-piece driveshaft, it connects rear-end directly to the transfer case (on 4wd vehicles) and the slip yoke gets it’s splines lubricated by the transfer case fluid (ATF). I wouldn’t put grease in this type since it’s going to mix with the transfer case fluid. May not do anything bad but who knows.
How far should slip yoke go into transmission?
CC: How much should the front yoke of a driveshaft engage the output shaft of the transmission? DD: The slip yoke should be able to go into the tailshaft of the transmission so the barrel is fully inside the seal. Then, pull out the yoke 1 inch. This is the correct amount of spline contact for the slip yoke.
How do I know if my yoke is bad?
Grinding and squeaking sounds from the drive shaft are frequently caused by worn universal joints. The joints become dry, causing the rollers to wear. Clunking sound, when going from acceleration to deceleration or deceleration to acceleration, may be caused by slip yoke problems.
Why does my truck clunk when I accelerate?
If you hear a clunk when going over a speed bump or hitting a pothole — and if that clunk is accompanied by a more metallic sound — that usually points to a suspension issue, which could mean a bushing, control arm, strut, strut bushing, or shock absorber needs to be replaced.
How much play should a slip yoke have?
For safe and stable operation, the slip yoke and spline should maintain at least 2 inches of engagement at all times.
