My wheel bearings never seem to last very long, by the time I`ve done 3-4 rides 250-300 miles of what I would call normal green laning and a mix of all terrains I start getting some play in them. I have always fitted my own and used many different makes and had the same problem on my TE510 Husky. I`ve put it down to my weight and size, I`m 6" 6 and 266 lb. Any thoughts people ? Cheers Bob.
