Jacob Ochs Posted February 4, 2014 Posted February 4, 2014 Hello I am having problems with my 4wd. I'm gonna have to replace all vacuum lines and I wanted to know what the check valve is an where I could get a new one?
yxmj Posted February 4, 2014 Posted February 4, 2014 Check Valve? If you mean the switch that activates your cad....it is located on your transfer case........ But maybe you should re-phrase the question..... :dunno:
ftpiercecracker1 Posted February 4, 2014 Posted February 4, 2014 Thats probably what he is referring to, the t-case switch i mean. Regaurdless if it is either the T-case switch or the CAD system, this will solve the problem. Jacob Ochs: Read. Learn. DO. http://comancheclub.com/topic/17377-cad-fix-1/

I did the CAD fix and I noticed it made the front driveshaft spinning and it wa vibe rating badly and I got less gas mileage so I decided to stick with the vacuum system

I've never noticed a difference. And, if the factory was gonna lose MPGs they never woulda done it .Any vibes indicate an issue with the shaft, not the fix.
Jacob Ochs Posted February 5, 2014 Author Posted February 5, 2014 What could be wrong with the shaft?
cruiser54 Posted February 5, 2014 Posted February 5, 2014 What could be wrong with the shaft? Bad u-joints, bad double cardon parts.............
Jacob Ochs Posted February 5, 2014 Author Posted February 5, 2014 I replace every u joint in the front end and got new hubs! What are the Cardon parts
cruiser54 Posted February 5, 2014 Posted February 5, 2014 Nope. But it needs to be done no matter what.
Eagle Posted February 5, 2014 Posted February 5, 2014 What could be wrong with the shaft? Out of balance. More likely, the slip joint may be worn out. That was the problem with the 2001 XJ I bought (which doesn't have a CAD, by the way). I had a horrible vibration that started acting up around 50 MPH and got worse as the speed increased. I could crawl under the front, grab the aft end of the front yoke, and both see and feel significant angular movement when shaking the yoke (slip joint) side-to-side. I tossed in a junkyard front driveshaft and it pretty much cured it -- enough to get me through the winter, anyway.

I've never seen that happen. :-\ Does that come with hard use, or are there better or worse shafts that one has to look for?
