I'm starting to think now that the vibration is not the wishbone, and something to do with the o/s driveshaft assembly. What is the bit called that actually goes into the gearbox, and how do you get it out? Does this part have a bearing? As the vibration does feel like a bearing worn, but wheel bearing doesn't have any play. (i have a 2 hour drive later, and i don't know if it will make it it, as getting progressively worse!) Thanks all, and happy Christmas.
