No. Alloy wishbones together with rubber bush rotates, and metal insert inside rubber bush stays still.
As mine have been on for 2 years and 40k miles I've ordered a pair of Birth uppers from AA, which have just arrived and, having thought about it, I agree with the above.
The top-hat metal collar can be slid out with thumb pressure, there is some grease in there but wouldn't do any harm to put some more in there.
When the long bolt is nipped up all the pressure is on the collars and the mounting, therefore the collars are held still.
Now, given that fact, it seems obvious that the rubber bush, which is under no pressure from the bolt, is intended to rotate around the collar and therefore the rubber bush remains stationary within the wishbone.
It also seems reasonable that with wear the bolt may loosen allowing the collars to turn on the bolt or the bolt to turn within the mounting, and could be the source of a lot of the creaking as you'd have metal rubbing on metal.
So, although I may be disagreeing with others in this thread (including the legend added to the image above) , for my money the OP's solution is pointless. The rubber bush does not move in relation to the wishbone.
I shall be doing the wishbones next week as I'm doing the front wheel bearings too. Will post an update following the work.
All the best
