The set in the daily have done over 250K over two vehicles, the rear bushes only last 30 (Meyle) to 40K (Lemforder) though so it's still a wishbone refurb / refit / geo job every year
.
Can’t we get them for the rear of the wishbone too then?
the wishbone rotates around the front bush axis, so replacing the stock bonded together, oil fiiled bush with a solid one that is much more durable is a straightforward job.
The rear bush is more of a rubber coated balljoint, and its internal compliance is necessary for it to move. A solid bush has so little compliance that the necessary movement can only be provided by the wishbone flexing, which it was not designed to do. And it quickly breaks as a result.
So fitting a poly front bush to a new wishbone solves the worn out(or incorrectly fitted; the results are the same) front bush problem. I just buy cheap wishbones, I don't see any point in fitting different ball joints or rear bushes until they're needed. Then when either needs replacement, GM parts are the way to go. And you'll get at least a couple of bush replacements out of a ball joint.
