JEEP WJ Rzeppa to Double Cardan Swap Grand Cherokee

- I changed out the rzeppa joint front axle to a double cardan joint. Doesn't vibrate much on the freeway and also doesnt make any noise. Its been about a month since the install and I am pleased with the swap! Make sure you have the correct yoke for your tcase when swapping or else you will have to make some adjustments how I did!
Thanks to the folks on facebook Jeep WJs Only for helping out with the yoke issue!

good to know of the splines that need to be ground (machined) down before I get into it! I just pulled a 242 from the wrecker today to swap out my 247, since I have a spartan locker for the front dana 30 (full time 4hi not compatible with lunchbox locker in the front). Old 247 has double cardan, which I will keep. [new] 242 has rzeppa (junk) for offroad.

I advise to replace the seals when you at it, they cost like 10 bucks. As well as the crush sleeve in the fwd axle.

[@edwindorlan4555]

Do you know for sure that the used shaft you used is from a v8 WJ? Everyone says a v8 ZJ will fit perfectly but I get mixed answers on whether or not a v8 WJ front shaft will fit some say it is not long enough.

[@jasonerbert]

Where did you get your shaft and yoke? Did you find a vibration after lifting your WJ? I just did the rough country 4” lift on my 04 grand. I bought one used tire to do a test fit and see if it was going to rub before buying new tires. There is a horrible vibration. I’m wondering if it is the Quadra Trac 2 seeing the substantially larger tire spinning different and putting the transfer case into 4x4 this causing the bad wobble. Good news is the tires don’t rub.

Hey everybody i need advice i bought a 04 wj in great shape this year and im getting pops and bangs from the drivetrain now sounds like its coming from the front leftside wheel, like maybe as if the front left side is locking up. I dont think i have varilock diff or lsd i doubt i do, i changed both cv axles in front diff and the front driveshaft with a stock cv rzeppa type. i disconnected the front driveshaft and no more pops and bangs , so is the problem the transfer case, the fairly new cv rzeppa shaft or the fact that the lift kit is causing binding maybe with the cv rzeppa shaft. I bought the wj with a rough country lift maybe 4-5 inch lift. what could it be i need the select trac to work because winter is coming. this will be the second time im changing the transfer case can the rzeppa shaft be causing a problem for my transfer case or visa versa because of a 4.5 inch lift??
