Easy to install and fixed my hub
My rear hub was grinding, and after replacing the bearings with this kit, it's buttery smooth again. The bearings seem high quality. Installation was straightforward. Much cheaper than a new hub. Very satisfied.

Good kit, but packaging could be better
The bearings themselves are great. My only gripe is that they were loose in the box and I had to search for them. But the fit was perfect, and my hub works like new. Recommended.

Saved my hub
I was convinced I needed a new hub, but this kit proved me wrong. The bearings are genuine and fit perfectly. Took me about 30 minutes to replace. Smooth ride ever since. Awesome product.

It's okay, but one bearing was slightly off
The kit contains good bearings, but one of them seemed to have a bit of play and didn't seat perfectly. I had to adjust with a spacer. The hub works now, but I was a bit concerned. Otherwise, decent.

Just what I needed
The bearings are exactly as described. My hub feels much better after the swap. Took a little time to figure out how to press them in, but I managed. Good buy.
