You're not going to be able to re-grease the bearing, and that's the flaw IMHO with the replacement bearing mount. There are bearings with a standard mount available on eBay and probably Amazon for small money ($80 or less), or you can just google "Jimmi Fix" and find out how to fix it for $10 and perhaps an hour of your time.Has anyone used the replacement EPS Drive Shaft Center support, and tried to grease the bearings in place?
If so, were you successful in prying of the bearing seal without damaging it?
And what grease did you use? I assume a good quality high temperature wheel bearing grease is sufficient.
