Is this easy to do??? I'm 17 and very handy do all my own work on my xj! Goin to 6 inches and bought a sye kit for it but idk if I should install it myself or what?... opinions??? If you have a link to a write up on how to on the np231 it'll be greatly appreciated! Thanks!

 

Go to Tom Woods' Driveshafts website. There is a great detailed write up there on installing a SYE in an NP231J. It is in PDF format and is easy to print.

 

Is it easy to do????

 

Yep, I installed mine last weekend. I didn't even remove my TC from my Jeep. I did it right underneath my Jeep.

 

How long did it take?? And should I just use a spare front driveshaft and the new. One???

 

It took combined actual work about 4-5 hours. You can use a stock XJ auto tranny front driveshaft for the rear if your Jeep is lifted less than 6 inches.

 

Mines like 6.25...

 

That's about the same mine is. The XJ front shaft was about an inch too short fully extended. However, the stock front driveshaft out of a V-8 auto tranny ZJ fits perfectly.

 

It took me few hours to complete the job and I have to press the needle bearing out of the and trim the shifter rail. Mine SYE is PORC
I use the front ds for the rear without any issue.

 

I like your homebrew press you made there. I forgt to say. I put my TC in 4LO before I started on it. That way I knew exactly how much of that LO range shaft had to be cut off to make the new shorter rear housing fit with the plug in it. I'm glad the XJ front DS worked for you. Now, you only need to carry one trail spare. PORC AA SYE is the one I installed in my Jeep, too. Best deal I found.

 

I have to cut something???
