    Jim: I agree with you, but I'm not sure that's what John is talking about. Does he mean the front "end yoke" # 25 is loose on the xcase shaft, or is the shaft itself loose in the xcase? Or is the "slip yoke" (the female part of the D shaft) loose on the splined section of the male part. If you remember I bought the female part awhile ago from you to rebuild mine (got new rebuilt one from lafster). If it's just that the slip yoke is a little loose on the splined section of the D shaft, it's no big deal since you don't drive at high speed with the front shaft spinning.

    Baby John--need clairifaction.

    John if you want to call me and talk about this, I can at least get a better understanduing of what the problem is and I explain how to fix it. I have rebuilt several of them and they are straightforward.
    PM me with your phone number and I will call tonight after 8:00

    Thanks very much for the manual. I intend to print all 247 pages and bind them in a notebook.

    Seems like we've all been wanting this.

    Here's a report for y'all. I found that the 4 bolts that hold the e-brake drum one were slightly loose so I tightened them up. I couldn't feel very much play at all in it last night but then again I was laying on my back and the mechanic was standing upright with the jeep on the lift.

    As far as the front drive shaft the wobble is at the front yoke. I think I figured it out too. The yoke simple slips onto the shaft and there's just a little bit of slack in it. It doesn't look like a big deal to me.

    I also discovered that there are no bolts holding my tranny mount to the crossmember.

    I imagine this may be part of my vibration when in reverse. I was able to get one bolt in and did a test and it might have slowed the vibration down some. The tranny mount is supposed to be threaded to receive bolts through the crossmember but the threads are stripped out. I was able to get a nut and bolt through on one side.

    I'll just buy a new mount before I swap out the tranny.

    Bad Bearing

    Every Jeep that I ever got --- and that is seven Willys and not the Kaiser CJ6 had to have the T-case bearings reshimmed.

    This is not because they are of bad design-- but because they are old old antique (over 20 years old when I got them) vehicles.

    If not fixed, the bearings will beat themselfs to distruction in short order.

    Many Jeeps run around for years somewhat loose-- but by the time I got my Jeeps the situation was critical and close to distruction of the t-case.


    I got my CJ6 expecting this loose bearing problem--

    I have not had a Jeep for 25 years before getting my CJ6-- so my previous several Jeeps were about 20 years old or so and had this problem--- this has to do with having more service on a vehicle than it was originally designed for in its entire life anyway.

    My CJ6 is 38 years old---and when I inspected the T-case--- no surprise---- the out put could be moved about 20-40 thousands of an inch from side to side.

    I suppose you could remove the rear output shaft.

    OK this is going to make me look really stupid but here goes.

    I printed the whole 247 page manual and it doesn't even cover the V6 models like I've got.

    I punched holes in it and bound it in a 3 ring binder.

    Anyone want it?

    It's for the L134

    John most will apply to your Jeep. Just stop at the tranny.

    John, I just replaced my tranny mount. When you replace the mount, instead of using bolts to mount it to the crossmember, red loctite a stud in it. This makes it nice and easy to get lined up with the crossmember holes. Just put on a nut and off you go ;)
