Is a slip yoke eliminator necessary?
However, any lift of greater than two inches virtually always requires a slip yoke eliminator installation and CV driveshaft installation, which will limit vibrations and won’t come with any of the issues often present in transfer case drops.
Is the NP241 a good transfer case?
The NP241 is a solid, reliable transfer case and superior to the NP203 it replaced. But as they age, the drivechain can stretch. This setup with the slip in the transfer case is also less reliable than when the slip occurs in the driveshaft itself.
What is the purpose of a slip yoke?
The slip yoke is an important component of any drive shaft assembly. The slip yoke assembly (pictured on the right) is what allows drive shafts and PTOs to flex or “slip” with their given application. The slip yoke is also essential for allowing u-joints to rotate properly with the drive shaft.
What did a NP241 come in?
The NP241 transfer case was in service from 1989-1999. It features an aluminum casing and is driven by a chain. It is a popular model, being found in numerous applications including the Chevrolet Blazer, Suburban, and Tahoe, as well as the 1500, 2500, 3500, and Van.
How do I know if my slip 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.
How much HP can a NP241 handle?
1500+hp. You’ll be fine with a 241.
What fluid goes in a NP241 transfer case?
Dexron III
| JEEP TRANSFER CASES | |
|---|---|
| Transfer Case Model | Fluid Type |
| NP241 | ATF (Dexron III or higher) |
| NP241-OR | ATF (Dexron III or higher) |
| NP242 | ATF (Dexron III or higher) |
Do you grease a slip yoke?
The slip yoke is lubricated by the fluid in the transmission/t-case. That does not need to be lubricated. That is not wrong. As for the splines needing grease, that is news to me, never heard of it.
Where is the slip yoke located?
driveshaft
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 is a slip yoke eliminator (Sye)?
To eliminate some of the problems mentioned above, we have designed a new super-short Slip Yoke Eliminator (SYE) kit which substantially reduces the overall length of the transfer case without sacrificing the strength of the unit. Our new SYE kit reduces the overall length of the NP241 transfer case by 9 inches.
What kind of Yoke does a GM NP241 have?
NP241’s are a common GM transfer case used in 1989 and newer GM trucks. Their main downfall is the slip yoke rear output which is not desirable on lifted trucks. This kit converts your GM NP241 to a bolt on (fixed style) yoke. Uses common 32 spline yokes (same as NP205), though the yokes needed to be shortened 1/4″.
What kind of drive shaft does a Chevy np241c have?
A true Slip Yoke Eliminator kit for the NP241C Chevy Transfer Case. This is not a hack and tap; it is a brand new 32 spline rear output shaft, new seal retainer and seal, and new output flange. The output flange is compatible with 1310, 1350, and 1410 series drive shafts.
Why do NVG transfer cases have slip yokes?
As with most NVG transfer cases, a slip yoke design is used with the rear output shaft. This design is prone to leaks and also contributes to a very long overall length. This long length combined with the slip yoke design often creates driveline geometry problems with lifted suspensions.
