Raymond,

I'd have to recommend putting it back on. The factory had some reason for them. Most likely to prevent the individual stresses on the separate bolts from snapping them off. When they team up in pairs due to the 2-hole plates, they're stronger overall and less likely to break. Plus, due to it's thickness not being there to take up bolt length, there's the issue of excessive thread protrusion on the backside of the CV flanges, possibly rubbing against something back there, like the output shaft seal. BTW, I failed to mention that the serrated lockwashers are absolutely critical to keep them from loosening up.

Don't take the axles off again, completely. Just take out two neighboring bolts at a time and reinstall those plates. FUN!

Mike B.

P.S. Hey, Boston Bob, if you're listening, I'd like to bring some parts by tommorrow.........

Hey

How important are those 2 hole washer things? I ask because I just found mine on the bottom of the solvent tank, and I'd rather not take my axles off again.
