Vibration when I hit the gas pedal...

I know it is more $$, but the SYE and new driveshaft is the way to go. Besides fixing the driveline angles it also seals the back of the transfer case in the even you have to pull the rear driveshaft due to damage on the trail.

x2 on this statement. With a SYE if you blow a rear driveshaft ujoint or mangle the rear driveshaft you can remove it and front wheel drive yourself out of the woods. Without it you lose your t-case fluid. Just an added security when on the trail.

Or you can just do what I do and get a cap, which installs over the end of the tcase and do the same thing for a whole lot cheaper than an SYE.

The only reason manufactures installed the slip yoke into the Trans or T case was because it was cheeper and it worked fine for a stock vehical. Once you start to modify the rig then the stress on the tail shaft housing becomes to great and wears out quickly causing leaks at the tail shaft seal from wearing brass bushings and bearings in the tail shaft housing. Installing a SYE benifits in many ways but more so for short wheel base vehicals like the CJ's,YJ's &TJ's to extend the drive shaft a few inches to help reduce the operating angle. The NP231 and other Jeep T Cases are weak at the tail shaft area compaired to a 1/2 & larger truck T Case housing and also the angle of the rear drive shaft is not even close to a short wheel base jeep. What im trying to say is a standard slip yoke in a Fullsize 1/2 & up truck will hold up to more abuse than a standard slip yoke in a jeep but still will wear out. A SYE is a stronger design and will outlast any standard slipyoke off the tail shaft. Ford installed alot of Slip yokes in there drive shafts. Guess they felt it was worth it. GM, Dodge & Jeep just went the cheeper way. I do have to say you rearly see a leak at the tail shaft on a SYE style setup.
BTW we went far off the subject of "Vibration when I hit the gas pedal" LOL
