I can't complain really Pete the car is mint and all the hard work has been done for me this time, just a few niggles 1 being the dash lights where all blotchy so I changed the el sheets behind the dials, 2 the heater didn't work so a quick flush and it's now fine, 3 outer cv boot and then this knock so not all bad. I think it is the tca ball joint but I just wanted to see if anyone has had the same symptoms
