I was unsure also that why I started the conversation. I honestly don't know what or if it could do anything but it worries me that it don't fit the same way it came apart!
I totally agree with nuand blu that it's a bad idea. I was just throwin it out there. I have thought of this though........somehow incorporating a high strength tapered bearing or even a heavy duty bronze bushing in that area. Both greaseable, of course. Ford used heavy greaseable duty bronze control arm bushings for years in their police car packages. Something like that would remove all of any binding that might occur. I'm no engineer, so I'll leave it up to somebody else to do. lol
All in all, it's a pretty good design as is, as long as quality parts are used. I mean seriously, the stock Mopar suspension has stood the test of time in just about every single type of racing possible.
