My left side rear went out, then a couple of weeks later the other side rear went out. My dealer told me that if the housing is not ruined you can replace the bearings, but by the time I paid for the labor, it would cost the same as just buying the whole new assembly.
The Bair products only has the wheels available. They said they aren't selling the bearings and assemblies until this fall (at the soonest). So you can buy the aluminum wheel now, but no bearings etc. Whick wouldn't help me much because my wheel only got messed up when my bearing went out.
On my second failure, I knew right away when it broke and I was able to stop before ruining my rollers.
Now I am just hoping I can make it without the others failing until I can buy them all from the bair people. That is if I can afford it. my drive motor went out last week and there is metal in my whole hydraulic system. It seems every dollar I make goes into repairs. But at least I am supporting the economy right!?
