I ordered a set of new Sachs struts and bearings (lemforder [sp?] I believe) and just assembled them.
There is a bit of slop if I rock the upper mounts. I checked the old (orig I assume with 160k) ones and they did the same thing. It's not much but I didn't expect any. I can't really detect any axial or radial play.
It's a ball bearing so I don't know that it could be any better. The nut is sufficently torqued and the bearings turn smoothly.
I've not had experience with replacing these before so I have nothing to compare them to.
Thinking about it I think once they're installed I should be good but wanted any other advice.
