Yes...this repair is rather quick, can be done in 5 mins or less. Its super easy too.
Right, it is just preventing it from returning to home position, though it seems to be working out so far.
However, on my drives the bumper was on the other side of where I was putting the foam at. Yes, on one drive; after I removed the top plate I saw a black streem of goo on the bottom magnets. But with the removal of the top plate, the rubber bumper and whole stalk or whatever its around comes with it. You can easily clean it off with a towel or such. I used the same towel to wipe the remaining goo off the stalk. Then replaced it with one of the foam rings but, I had to shave its sides down a tad.
This was also easy as the ring just slipped over the lip and fit into place. I'd love to hear if anyone else gives this a go and hear their out come, also gladly will help.
