I pulled the rear wheel on my 2003 today to change out the wheel bearings to some premium SKF units and discovered that the shop had assembled the spacers in the order that they are on later models when the put on a new tire.
Instead of going through the seal and bearing against the inner bearing race, they somehow managed to get the large diameter spacer in place and pushed up against the seal. (The hole in the seal on a 2003 model is too small for the large diameter spacer to fit through)
I've been riding it like that for a couple thousand miles.
Nothing seems to be damaged.
I replaced the dust seal with the standard seal for a 6204 bearing and the hole is the proper size for the small diameter of the 2 diameter spacer to fit through.
This leads me to believe that Suzuki uses something other than a standard seal on the later models,...a seal with a hole large enough for the large diameter spacer to fit through so it rests against the inner race of the wheel bearing.
,..lots of potential for confusion on the matter.
