Okay, so I have 6 or so inches of lift and a stock driveline. My XJ is a '91 so I have the old style output shaft. Needless to say, there are some vibes present with 4.10's, especially at freeway speeds. Since I have lifted the jeep, the slip yoke is slid waay out of the t'case. There is maybe 2.5-3 inches of polished surface sticking out of the case.
With far less spline engagement for the yoke, I have noticed alot more side to side play in it. I would bet that with about twice the length of slip yoke splines inside the case, my vibes would be substantially better.
So, the plan is to redrill my homemade spring perches to move the axle about 3/4" or so forward. I will have to drill the plate on top of the leaves to match also. This should move my slip yoke about 3/4" forward into the t'case, nearer its stock position. I don't want it completely back to its stock position, or I would risk ramming it into the transfer case with full spring compression. But with more of the spline length engaged, the play should be less and strength would be increased.
Hopefully this will not cause too much tire rubbing on the front edge of the fender opening.
Yes, I am aware of the longer yokes available. Yes, I am also aware that slip yoke eliminators are a much better solution. The neat thing about this idea is that it costs $0.00 and takes about 2 hours to do. I have NO CASH and I need the Jeep ready for Moab next Thursday.
What do you guys think?
