		     I    mounted the nose wheel in the fork and was not happy with the bearing    situation.  It appears to me that the wheel is spinning between the    bearing and the center rod not rotating the bearings as it appears to be    designed.  Does anyone else have that problem.

   In    my thinking the outer sleves on each end should exert pressure inward to the    bearing to hold it to the center shaft so that the rollers can indeed roll not    slip between the inner race and the center rod.

   This    may not be very clear but if someone knows what my issue is and wants to call    me feel free.

Gary, I had a similar problem with my nose gear. I  kept getting a nose wheel shimmy on roll out. First I re-tightened the fork (as  recommended by Vans), It loosens up after a while. I then noticed a lot of side  play with the tire and bearings. It seemed as though I was getting the torque on  the bolt but the sleeves were not compressing enough to tighten up against the  bearings. Vans suggested shortening the axle a little bit so that the fork would  squeeze the sleeves tighter against the bearing. After about ten landings, the  shimmy was back. I took it apart to find the sleeves had been ground down to the  shape of the bearings outer surface and every thing was rotating. After a  lengthy discussion with Vans ( they found a similar problem on their first 10)  they sent me two large diameter aluminum washers ( about 1/8 or more in thick)  to put on the axle against the bearing to provide more surface area to push  against the bearings. You have to cut down the steel sleeves by the thickness of  the new washers. Haven't had a problem since!!   A few notes however (  for everyone ), apparently most RV's have some shimmy during rollout( mine  included). I still have a little in the 35kt range, but not nearly as extreme as  before. Secondly, not all 10's are having this problem for some reason. Van's is  thinking about some sort of solution such as replacing the existing steel  sleeves with thicker material that provides a better area to press against the  bearings. I don't think at this point that all builders should expect new parts  heading their way as some people are not having a problem. I would certainly  call Bruce or Ken K. and mention your problem for the record though and ask  about the spacers I got. Mark (40016) 45hrs.

Just a reference to the other nose wheel problem.  The new Matco wheel provides about 1/2" clearance for the valve  stem.

I  called Van's today and outlined my problem.  They are aware of it but don't  have a fix yet.  He wasn't sure when they might have one.  So, I  devised my own.

 I made  two aluminum washers .030 one for each side of the spacers next to the  fork.  Then I lubed up the bearing good and put a bead of JB Weld on the  inboard end of the spacer and mated it against the bearing.  After cure I  trimmed it back to just clear the seal and yet claim all the metal surface area  possible.  Not it looks like it is working like it was  designed.
