Rear Wheel/Final Drive GL1500

That tube just sits in there, and is held in place by the tension created by torquing the axle nut. Just as the spacer tube in the wheel takes up the space between the bearings - the spacer tube between the wheel and final drive sets the clearance between the splines on the wheel's drive flange, and the splines in the differential.



I had the tire rubbing issue on my 1200, with an E2. It went away when I changed to an E3.

my 1200 has one too.

It is part #18 in this diagram. I replaced the diff. on my '88, with one from a '99. The '88 spacer was turned on a lathe, and the '99 one was a piece of tubing, expanded on one end (cheaper) - both measured the exact same overall length, tho.

Thanks for the replies. Having looked at the diagrams for my Wing (1993 GL1500SE), the tube appears to have an expanded end whereas the one I have is just a straight piece of tubing. If this tube has worn or be damaged could this be the cause of the tyre rubbing ?

I am using Michelin Pilot GT's and never had this problem before. The wheel runs true and the tyre appears to be fitted correctly.

The "flare" I mentioned on the diff. end of the tubing is very slight. The critical dimension on this part is the overall length - as that sets the distance between the inside of the outer diff. case, and the inner race of the left (inner) wheel bearing.

This part is static, sandwiched between the above mentioned components, and held there by the torque on the axle nut. I don't see how it could wear to effect a change in the overall length. I went over this when I had the same problem with my 1200.

The threads should still be around. Try searching "tire rubbing". Corrosion of the swingarm, and other potential causes were mentioned - but the tire change ultimately fixed it on mine. I never did find anything else wrong with the thing.

Good Luck.
