Condition Notes
- Good shape some wear, but overall good condition
- Looks like a groove slightly under the spot for the o-ring under the splines.
- Bearing is used and still installed, some surface rust on this. The bearing should be good to go, but I would recommend replacement if you are performing this installation. I could have taken it off, but I figured I would leave it on here because these bearings might be tricky to find otherwise.
