CJ rear drivesahft bind after lifting or new springs
If you have lifted your early CJ or, have a new set of springs, you may feel the driveshaft bind when rotating it while extended. In other words, if you let the rear end hang down on the springs, the rear driveshaft will bind when you try to rotate it. This is not good. It can be remedied by installing a higher angle capable flange yoke on the transfer case brake drum. You should also drop the transfer case cross member down about 1/2" with solid spacers. This will greatly improve the slip yoke engagement as well as the angles.
I had to update this. It looks like the part number was wrong and the link went to a wrong part. I hope no one got messed up on that! Anyway I have added the right part number and link to a source that does have some.
