This all leads to an issue I'm experiencing, and I'm not sure if any of you are, or might.
When the strut is assembled and the top night tightened, as long as the spring compressors are on, the bearing and mount turn well, with the shaft rotating along with the mount. Ease off the compressors, though, and the bearing/mount acts like it seizes up and doesn't turn. You can get some movement by just breaking loose the top nut, but that's obviously not how it's supposed to be assembled.
Discussing it with others online, the two main theories are that the new OEM bearings are out of spec and the spring seat region of the lower part of the bearing are deflecting or distorting under the spring load against the top half of the bearing. This has happened with both bearings and both mounts in any combination. I ordered in a set of KYB bearings/mounts that I'll try to get assembled this weekend to rule that in or out.
The other theory is the spring pressure is pressing upwards with enough force that the piston is pushing against the top of the shock body enough that the force/friction is keeping the shaft from turning. Breaking the top nut loose lets the mount/bearing rotate again because it's not being detained by the top nut. Putting the car on the ground should unload the piston and the bearing/mount and it should be fine. Theoretically.
Any experience or ideas? Thanks.
