What is a fixed yoke?
With a fixed yoke the yoke at the t-case is fixed in place (hence the name) and the driveshaft gets longer or shorter as the axle moves up and down. There are a couple advantages to a fixed yoke.
Is there a slip yoke eliminator for a jeep TJ?
Shop Wrangler Slip Yoke Eliminators. A Jeep TJ or YJ runs into a massive problem when lift heights increase: the driveshaft slips out of the transfer case. To solve this issue, the slip yoke is eliminated with an SYE kit (slip yoke eliminator kit).
What to do if slip yoke slides out on Jeep Wrangler?
By installing an SYE you convert the slip yoke to a fixed mounting flange which prevents the risk of your driveshaft from falling out and also allows for a CV driveshaft to be installed. When the slip yoke slides out too far it runs the risk of falling out of your transfer case.
Can a slip yoke eliminator reduce driveline vibrations?
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.
What happens when you install a lift kit on a Jeep Wrangler?

Can a jeep yoke slide out of the transfer case?
However, once the Jeep is lifted it changes the driveline angle beyond what the slip yoke can cover. This will cause excessive driveline vibrations, or worse, the slip yoke can actually slide out of the transfer case. With smaller lift kits, it is possible to avoid this problem by using transfer case drop brackets.
