Shocks don't pivot easily on mounts. Should they?

I've got TEC shocks on my Scrambler, which I've just removed to replace the TEC OE springs with the lighter version and refitted to the bike. When I took the shocks off, the bushes were all seized fast to the frame and swingarm lugs. Rather than butchering the bushes to get them off, when refitting the shocks I just pushed them back over the old bushes and set the bolts to the required torque.

This presumably means that any pivoting of the shocks on their mounts would require the rubber cushion inside the shock eye to revolve on the bush, rather than the bush revolving on the frame/swingarm lug. Seems to me that this would a) cause any movement to be sticky rather than slick, and b) wear the rubber cushion.

Is there in fact any revolving movement of the shocks on their mounts as the suspension moves: does the geometry change slightly as the shocks compress and rebound? Or am I fretting about a problem that doesn't exist?

If it is an issue, what would your suggestions be, please?

By bush you mean the steel sleeve? The shock eye, rubber bush and sleeve would all be bonded originally. Angular movement is taken up by the rubber flexing, as the sleeve is locked solid. I don't think you have any problems the way you have it, in fact some shocks come without the steel sleeve. Just make sure you have a keeper washer in case it separates.

You know, I've been wrenching for decades and it never occurred to me that those oversized washers or sometimes a flanged nut had any other purpose than to look good. Learn something new everyday, many thanks.
