While changing my tires this weekend on my 99 Electra Glide Classic, we noticed that the bearings were in need of replacement. While changing the bearings, we noticed that there was not a spacer in the rear wheel. The bike has 39000 miles, and I am not sure if there had ever been a rear bearing replacement before. The previous owner allways had the dealer service the bike. Does it sound far fetched that the factory did not put a spacer in the rear, or maybe the dealer forgot to replace it?
