Spindle seal kits??
 

Hi guys,
Anyone out there have any experience with the Bearing Buddy Spindle seal kits? I bought some and am a little concerned? It's a great idea as far as the seal riding on the smooth stainless collar. But the large rear bearing rests against an O-ring?
I can't believe that O ring is going to support that bearing?
Or should I just keep replacing bearings and seals every couple seasons?
Thanks for any input,
Darren
