Rear Shock - Play In Top Mount.

There’s some noticeable play in the top mount of the shock/swingarm of my ‘86 SL. Can’t see from the Stein Dinse parts diagram https://www.stein-dinse.biz/eliste/index.php
Is there a replaceable bush/bearing?

 

Thanks, still not 100% clear on what I’ll find when I take my shock off, bearing, bush ..? I might just get the bike raised up and see what’s there.

 

Thanks, will look through all the info.
