I have Sledge on my ignore list. I don't see his posts and life is so much better now. Kind of like getting that annoying pebble out of your shoe.

Good idea Addy but I put him on my ignore list earlier today and it isn't working, I'm still seeing his obnoxious posts.  If it doesn't work by tomorrow I may put this forum on my personal ignore list.  I've noticed him using this same insulting demeaning attitude on other members who have disagreed with him, he started it with me years ago.  Obviously he doesn't how to disagree without being disagreeable.

you have to go into settings jack and check the box that says do not show posts from blocked users... or something like that .. addy had to do the same initially

Found it under Look and Layout. Done. Now I won't have to delete the ones to me.  Thanks Janx.

... sledge while nit picky has a range of technical range putting him in a league of his own.

Cool.

What he says while correct, can be largely irrelevant ... like a bearing's axial load in the GS'es assembled wheel ... like whatever ... it would never get loaded that way unless you took the wheel out put the axle in, and hit it with a "sledge" ... he he ...

Cool.

About the bearings, I replaced all four in my 02 as mentioned above and all 4 were driven in solid against the bottom until the bell rang tapping all around. The spacers then were not tight, didn't move laterally but did move radially with the little pinky applied.  The bearings turned free and smoothly.  Obviously the bearings must have had a bit of preload when the axle bolt was tightened.

I have the wheels from my old 97 that son JP parted out after he was done with it and just took a look at them, had them on my 02 with different tires I was trying and they're back off now.  Still with the original bearings and 120k miles on them the bearing inner races feel a bit looser due to wear but they were tight up and the wheel couldn't be moved laterally when they were shaken when last on the bike.  I could lift the inner spacer with my little pinky and hear it fall, it was loose but snug as a bug when wheel was last mounted and tightened down.

I don't doubt what bmf and mitch79 reported above about the bearings going tight when the they were driven in and it was necessary to back one off a bit.  Seems they are 03 and 06 models and probably assembled in Spain and could be they changed something in the fitment of the bearings, I don't know can only speculate. I prefer the way mine are all fit up tight since with the high mileage I put on them sooner or later they would be floating wheels I think.  Maybe that would compensate or assist the floating rotor.   :icon_lol:  Hope someone doesn't take off on that joke now.

Thanks for the input on yourself Buddha.  I went to work in a garage when I was 15 and worked full time summers and part time winters thru high school and college.  With my early interest in cars 65 years ago I would probably have taken EE courses instead of ME if I had known what they were going to do to cars between then and now. I took off my Engineers cap and put on my shade tree mechanics cap when I retired 19 years ago.

On the wheel bearing - the sleeve will sorta rock a little ... if not you will never be able to get the drift onto the race to remove it.

Essentially put new bearings in, and if its as it was before it would be OK.

The worst bearing cases are typically on bikes that have been parked for years in weather and rain ... super low miles and sit for years and years.

Cool.

"tapping on the inner race to sit it up against the spacer so it is free to turn correctly. Do it this way and there will be no preload on the bearings to bind them up".

Sorry mate, but (in spite of your APPARENT expertise) you have just unveiled your complete lack of knowledge 'real-world' engineering principles.
Tapping of the inner race will certainly damage the roller balls and/or race to some extent. An absolute no-no.

A couple of light taps on the inner race to get the bearing into a final position wont harm it, particularly if its the float end where the housing diameter will be at the upper and of its tolerance and the outer race comparatively loose in relation to the fixed end and free to travel in the housing.

But.......beating hell out of it will  :thumb:
