I suggest you clarify your problem because it probably doesn't make sense to anyone :?

If you post it in Italian, perhaps somebody on the forum could understand it or have a friend with better English explain the. I would hesitate to guess. Sometimes even Americans and the British have difficulty using different words for the same thing. Pictures help, also. You can use the part numbers from the parts book as well.

If I understand the issue, I recommend the following thread for background info.

I think he has a rear disc brake, so different spacers? Disc not aligning with caliper?
A picture is worth 1000 words; I just don't have pictures of the rear disc setup.

The rear wheel is a MKIII with disk mounted on his standard MKIII swing arm.
All the parts (right and left) are fixed in place Like part list but when I squeeze the axle assembling (on the right side) the wheel tends to hang and does not depends on the caliper because the disc turns free.

I'm not good at searching, maybe somebody can help with that - just gave a try and can't find the post.
But I had the same problem on my rear wheel reassembly. It has to do with getting the spacers in the correct order on the speedometer side. If not mistaken there was some discussion on the thread about some folks having to reorder the the assembly of spacers from the factory diagram in order to work, etc.
Edit: found the thread I believe I used to solve my problem, hope it helps with yours:

On the numbered drawing above, seal 25 should be to the right of bearing 23 (it is correct in the unnumbered drawing above).
It is vital that spacer 30 only contacts the inner part of bearing 10 - also on the other side, spacer 11 should only contact the inner part of bearing 23.
When everything is tightened up correctly, the wheel is turning on its 2 bearings and the sprocket on its bearing.
Sometimes when you tighten the nut on the left hand side (speedo gearbox end) the wheel will not turn due to the gearbox catching the sprocket - I put a thin washer between spacer 11 and bearing 23 to cure this. - Alan

This is the main thrust of the issue. It can even be checked with the wheel off the swing arm, using some spacers of course. Wheel binding from tightening the axle is either an external rub like the speedo box, the brake cover plate or the bearing spacers are incorrect.regental said:
Check to see if your speedometer drive (31) is rubbing on the sprocket (22). If it is, the speedometer drive (31) will rotate when you turn the wheel by hand. That would indicate that the drive IS rubbing against the sprocket and that you may need to re-arrange or ad to the spacers to gain clearance.

Re: Mk3 Rear Wheel Reassembly - Need some Guidence
One other thought is the replacement bearings, since I spent too much time last year with replacement bearings that were slightly wider than stock or not fully seated or hub distorted by previous bearing replacement. Or wheel not centered (by a professional who charged $$$). If bearings are well-seated and all the spacers are in contact with the inner races, then tightening the axle should only put tension on the inner races and the wheel should spin freely. If inner spacers are flopping around (loose), then tightening the axle puts stress on the bearings themselves. If this doesn't cause binding, it will lead to premature bearing failure.
Good luck sorting this out, Piero.
