Bushing preference LCA, UCA

10-4 ...... did one years ago. Some have said they have issues (walking/moving) but obviously they sell 'em. I'd go with old school complete with shells - but again, would need to find someone I could trust with a press. The only difference I can see is the Moog and OEM style have the rubber "bonded" (probably poured/molded in mfg) to the shells, where the poly aftermarket are obviously "floating" (though tight fitting) within the old outer shells - doubt the bonding makes them function any better as the primary function is the cushion/barrier between the hard/moving parts .... correct ?
