I wish I had seen this before the past weekend. It would have saved me so much headaches. I needed to change my axle seals on my 87 YJ, and thought the seal was at the diff. If I had known that it was at the vac DC, I'd be a lot happier person at the moment. Doesn't help that I still need to get at the one on the driver side, but I'm glad I now know what's up with the passenger side! Thank you for this.
My 89 XJ Had a bearing just inboard of the CAD housing that the old axle would ride on. The new axle was a tad bigger than the bearing bore. I had to remove the bearing. Not something I had seen on any how-to videos. Just a heads up to others.
I forgot to add, aren't there two seals around the Shift Motor Housing? The original manual says to "add 5oz of GL 5 gear lube through the switch hole." If it was lubed with the main differential, why would we need to add additional oil? Just a bit confused here is all...And Thank You for taking the time and creating the video!
I did something similar. The shift fork is held with a clip on the shaft. You can remove the clip, slide the shift fork to one end and put the clip back to pin it to the other end. That then locks it. I think removing this assembly is better overall for tough 4wd driving since it is a fail point but for regular 4wd work its fine. The only drawback is you don't get that 4wd light coming on which the cable kit will do for you.
4x4 is not always engaged since the T-case is not engaged but yes, the front axles will spin on both sides. The driver side does anyways with or without the solid axle. It will essentially be like every other solid axle Jeep without CAD.
Great video, but I have a question? When you add the solid axle to the right side, then engage your 4 whl dr. and if you don’t have some kind of locker up front, you would have an open diff. the wheel with the least resistance will turn. So technically you still have a 3 wheel drive, if you have a trac lock in the rear?
that is true even if you leave it with the factory set up, just like all non locking front diff 4x4s. this modification just gets rid of the 2 piece right side axle wich has always been a week/trouble spot in early Jeeps, even Chrysler knew this and got rid of it by the mid '90s and went to a single piece axle on the right side.
@@johnewald9650 typically if you have a locker up front this is a mod you would do at the same time. It just gets rid of the vacuum issues. You just go to a solid axle.
0:57 unreliable? LOL You put a cable in (that freezes up in snow/slush; I ran one for 3+ years) to ‘fix’ a VERY reliable oem axle disconnect. Nothing wrong with it. Just because it needs a new harness or vac motor after 25 years doesn’t mean it’s no good.
Do you have a fix for the 4wd light or do you forego it? Can the button actuator be remounted like on the 4wd shift lever so its pressed when the lever is pulled?
I was wondering if someone had a part number for this? I didn’t see it listed in any of their comments but I may have missed it so if someone could help me out that would be awesome!
