Here's a puzzler...<p>I recently installed new 3 new u-joints in my 1800ES driveshaft. Now 2 of the 3 are loose in their yolks. The cups slide back and forth a bit, as if they are either too short end-to-end, or the retaining clips are too thin, permitting movement.<p>When I installed them, I did use emery cloth just a bit to clean out the yolks, but they still took a press to install them.<p>The simple and stupid thing to do would be to squeeze (hammer or press?) the yolk tighter, but I fear that they would no longer be parallel. Or I could shim the cups in on the ends to keep things tight.<p>Suggestions? Can you knurl or otherwise tighten yolks? Is this fixable, or am I looking at a new driveshaft?

Re: U joints and driveshaft yolks (Phil Singher)

They looked right and were a tight fit going in.<p>Got em from IPD. The bigger ones would never fit, and the smaller ones would fall out.<p>I somehow suspect that the retaining rings are too thin, not taking up all the space in the groove. Possibility?

Re: U joints and driveshaft yolks (RonG)

In that case, the clips would be rattling around in the grooves -- you could check. I think the most probably thing is that the joints were machined undersize, ot the caps are too thin. Just because they're new doesn't mean they're right. Either that or the yolks on your shaft are bent, which is less likely but can happen.<p>It is an odd one, I agree <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0">
