I have changed the back wheel at least 40 times on these bikes over the years but have never seen this come out before. I am working on a guys bike from here and he said it was pulling to the right and wanted to make sure the differential bearing was good.

Differential? On a single-wheel drive system? Rear drive bearing maybe? But even than, I've never taken the rear end further apart than just removing the rear wheel; and only have replaced just the rear wheel bearings once but they were REALLY bad at the time. Can't tell what that picture is showing (a bearing and spacer maybe?) but I'm sure someone will be able to help.

The piece on the axle came out of the final drive/diff same difference.
 
just a collar that typically never comes out... should be fine.

But, there are bearings in there so if you can feel them and see if they are notchy, might as well check.

Thank you, I found the diagram and thought it was Okay but will definitely check those bearings.
 
Hi, spacer coming out with the shaft not a problem, it's job is to center the wheel in the swing arm,and keep the weight and side loads off the final drive bearings. The early Silverwings had a few spacers that were to short and would destroy the big bearing in the final drive. To long of a story to say how I know that. A quick check would be pull the fill plug on the final drive and see if it has any metal particles in the oil. G

The final drive service is on my list of things to do while I've got it.
 
Bearings feel good and the fluid is old but can not find any metal with a magnet, so I think it is alright. I've just never had the spacer come out before but then again, I've never seen this much sticky grease applied to the axle.

The differential is separate from the wheel bearings so it can not cause a drift or pull.

Surprises the heck out of you the first time it happens. I can't even remember if it was my own high mileage rear drive or someone else's bike I was working on but what a surprise it was.

Short answer: happened to me only once and i can't remember it ever happening again.
 
Yes it'll come out occasionally. Clean it, grease it. Put it back.

The ST1100 has a distance collar looks like a tube and it is possible to insert it the wrong way round - except it has a very slight taper and one end has a ground texture. You have to make sure it goes in the correct way - otherwise the caliper bracket and axle spacer will not fit in the swing arm. No such problem with yours though.
