Should a nylon suspension bushing have an interference fit with the shaft it rotates on?

My thinking was that if the bushing is acting as a bearing with a with a film of grease then it should be a running fit, but guys in the field seem to think interference fit is right.

This particular case is an aftermarket lower control arm bushing for racing. The bushing and shaft were machined so they would assemble without force. However after the bushing and the outer sleeve were pressed into the lower control arm, the shaft to bushing became a press fit. The outer sleeve taken from a stock rubber bushing assembly is compressed and transfers that to the nylon which in turn reduces its inner diameter.

The shaft bolts to the engine subframe (aka K-frame).

Matt, your link is doing the same stuff it did before? I just had Faye (Webmaster Wife) here and we tried several things to make it work but it's a no go?? Don't know what to tell ya as I posted pics here late this afternoon with zero problems so it's not our software or hosting service.

Edit, I deleted your img tags and checked the box to stop the software from automatically parsing URLs and it just puts the link there so ppl can copy and paste it in their browser. That link works so it has something to do with the software automatically parsing URLs but I got no clue as to why. :-k
