Rear Drive shaft???


Recommended Posts

Does anyone out have advice on the rear drive shaft of my comanchee? I have a 8.5-9'' lift with a dana 44. I do have driveshaft vibration, it aint bad but it aint good either. My question is, since we have a longer wheel base then a xj or tj do we really need a slip yoke eliminator? Should I just extend the driveshaft and keep the stock configuration of the slip yoke on the output of my Np 231 or should I upgrade to a SYE with some time of CV shaft? Will a CV style shaft work well with the longer wheel base of the comanchee? Thanks guys.

With that much lift, I would probably bite the bullet and get the SYE and new slip driveshaft. TJ/XJs should seriously consider the SYE after 3". Comanches should seriously consider them after 6".

 

Are you still using the stock driveshaft?

T-case drops are generally frowned upon. They will help the rear driveshaft angle slightly, but at the same time will make the front driveshaft angle slightly worse, eat up ground clearance, and can tweak the t-case shifting bracketry and cause problems. It's just a bandaid and not the proper way to do it.

Excellent description ;)

 

SYE is easy to do and a drive line is cheap. PORC has SYEs generally cheap and if you do it they usually have the 32 spline rear outputs. It'll take you 3-4 hours to install it and I recommend doing it on a bench even though you have plenty of room to work with that much lift.

:agree: To a point. don't go cheap with it. If your going to spend the time and cash on it do it right. You can check the net for alsorts of companys that make them. Advanced adapters along with Novak adapters make some great kits for a good price.

There is absolutely nothing wrong with the PORC SYE kit. It is virtually identical to the AA kit. I've run one in my XJ for many years with no problems. I just recently put the t-case in the MJ and got a custom-made driveshaft from J.E. Reel.
