I had my suspension fully rebushed and new ball joints, except for the rear radius arm bush, before the fault occured.
Here is a recent thread discussing the wheel bearing topic. If you have ABS, you will need the hubs. I'd recommend a "premium" branded part costing around £100 each.

I would definately be doing a refurb at that milage; bushes, ball joints, shocks springs, disk guards maybe even caliper over haul, strut painting, lever arm blasting and painting.
Another possibility is bent rims, but the tyre place should have checked for that.
