So I have Tom Wood's Driveshafts F&R . . . had the center ball replaced on the rear shaft Dec 2009. Rubi 4" lift 33" tires, Double Cardan Rubi DS. Noticed a noise tonight that reminded me of the noise my Rear DS made last year before the center ball went bad . . . so I turned around headed home (drove less than 5 miles) . . . it was only making the noise upon deceleration and under 2000rpm. I yanked the rear DS and drove around in 4x4 and sure enough the noise was gone. I didn't notice any play in the DS when on the Jeep or in the CV joint like there was last year when it went bad so I greased up the CV real good, sprayed some WD40 in there figuring perhaps some grit or something might have got in there and then greased it up a bit more, threw it back on the Jeep, greased the U Joints and Splines and the noise is gone.

So here's my question, what are the odd that I caught the issue in time and perhaps it was just a bit dry and needed some grease or some grit was in there compared to the odds that it's shot, will need to be rebuilt, and all I've done is temporarily masked the issue?

Yup your fine. I grease mine every time I do a oil change. They dry out really fast. Just grease it every other time you come back from the desert and it will last a long time.

Yeah, I'm going to pull the front and grease it up too this week . . . Guess I'll have to do this along with oil changes too. I've put maybe 5000 miles, but it has been close to a year. I just hope I caught it in time and don't have to rebuild the damn thing in less than a year.

You don't have to pull it to grease it. You can grease it in place.

I'm going to see if I can manage to grease it while it's on, but from what I recall, I couldn't get to the Center ball with it attached.

yup just rotate the driveshaft (flat ground jeep in neutral) you can get to it! If I can you can.

New Question . . .

I noticed what seems like a bit of play in the U-Joint on the Front Drive Shaft at the diff. Play might not be the best word as it's not loose where you can rattle it around, but it seems as if the center of the U-Joint is able to move a tiny bit side to side in the yoke of the DS (doesn't seem to do it on side of the U-Joint that attaches to the diff). Hard to explain but it seems as if there is a little space under the cap of the U-Joint and you can move the center part of the U-Joint in and out of the cap a tiny bit, you can't twist it, the caps are tight in the yoke and on the U-Joint but are able to slide the center of the U-Joint between the two caps a tiny bit. Is that normal?



( < + > ) - Visual . . . ( = the caps, + = the center of the U Joint, <> = the movement sliding the U-Joint back and forth in and out of the caps.

Pulled the shaft and there is definitely movement in the U-Joint . . . it's tiny maybe 3 hairs next to each other, but there is movement. With the shaft off, you can move the middle of the U-Joint back and forth in the yoke, the caps don't move in the yoke just the middle part of the U-Joint will a tiny bit back and forth in and out of the caps. The yoke looks fine, the clips on each side appear to be secure and in place, even the U-Joint looks fine with plenty of grease. I don't know if this is just something simple and routine and the U-Joint was just bad or wore faster than usual or if it isn't seated properly or if the yoke is a tiny bit too wide creating a tiny bit of space. I guess I'll call Tom Wood in the morning, but I'd really rather not have to deal with the hassle of shipping the driveshaft out to UT or wherever he is if it's just something normal and simple. Still a little frustrated to have to deal with this seeing how I just bought the front shaft in Jan and have only put 4000 miles on the Jeep. I probably wouldn't have noticed but after having the issue with the Rear which I had rebuilt a month before getting the front, I wouldn't have even noticed. I've put about 250 miles on the Rear shaft since having that noise and lubing it up, the noise has not returned and I do not feel any play in the shaft, but I don't know if I'm out of the woods on that one, and now I'm driving around without a front DS, which was my insurance plan as I figured I could take off the rear shaft and just drive home in 4x4 if needed, I guess AAA is my only insurance now :mad:
