MAJOR UPDATE - PROBLEM FIXED
I wanted to share a major update with you, I have had the problem fixed this morning.
After all the crap I have been through, I took it to a garage this morning and it turns out the wishbone bolts weren't properly torqued, despite everything being torqued before.
Literally the chap went round and torqued everything about 20 mins and took for a drive, came back and said its fixed. I didn't believe so went for a test drive, OH MY GOD, the car is totally silent now and it feels stiffer.
I am chuffed to bits!
Thank you to each and every one of you who has tried to help me resolve this issue. I have spent many a night reading about ways to resolve! Thank you.
