Thanks for the information Dave, I've already replaced the shocks as they were overdue and the coils look newish with no rust or hairline cracks.
I'll see if I can get a recording of the noise and upload it here. I've got plenty of time to find the problem as I don't go back to work until the second week of January.
One thing I didn't mention previously it the car is quite hi milage 150k but had a timing chain fitted not long before I purchase the car, so a thought is just to replace the drive shafts ect.... But if not needed why waste money but on the other hand I could end up replacing parts that need doing then 500 miles down the road something on the other side of new parts might need doing.
Anyway I'll see if I can get the noise recorded and post it.
Thanks again 👍
