Sloppy yokes. Need advice.

I'm in the process of installing a limitted slip carrier in my rear diff. (AMC 20). Upon pulling it out, I noticed that both u-joints don't fit tightly in the yokes. The jeep ('78 CJ5) has about 4" lift (2" springs, 2" shackles).
There is about a 1/4" tapered shim tipping the pinion up so the angle at the rear isn't too bad but the angle at the transfer case (Dana 300) looks pretty extreme.
Is it better to have both angles the same (ie. take out the shim)? Is there an easy way to lower the transfer case?
Also, what does a CV joint shaft look like? Does it use different yokes? Since I have to change both yokes anyway, is that a better way to go. What is the best source? Keep in mind that I am very cheap by nature. Any home-remedy solutions are welcome.

Re: Sloppy yokes. Need advice.


My 78 CJ5 with an AMC20 and a D20 has almost the same (but not as much) lift as yours and the drive line vibration is not good. I plan on installing a CV joint to help the problem when I install a CJ T-18 next month. This will require changing the yoke on the transfer case to fit the bolt plate of the CV Joint. Look for the Tom Woods ads in any 4x4 rag and you should see how the CV joint works. It's like you have a extra joint in the drive line at the transfer case. The yoke at the rear end will be the same. Unless the members of this BBS suggest otherwise, Tom Woods is the way I will go.

Good Luck!
