Product review (5 stars): I'm a week in and so far so good.
Fit perfectly. I read someone else review somewhere and ended up having to do the same thing. I had to grind off 4 of the 6 bolts as they just spun around. I went to the hardware store and matched the bolts and washers. The nuts spin because they use a permanent thread lock on the bolts and the nut is encased in plastic. When you start to loosen the bolt, most of the time the plastic isn't strong enough to hold it and it strips out. I used an epoxy glue to hold the nuts back in place (make sure not to get any on the threads) and when it dried I put it together. I Installed new bearings and now everything is quiet again. I'm a week in and so far so good.
