Getting heavy creaking n groaning on full lock from the front end. A few years ago I replaced a couple of ball joint boots. At the time I noticed that the joints were a bit ropey. I think the time has come to replace them. I've done the central steering pin already. Time/equipment and home life doesn't allow for me to do it so I need recommendations and rough labour guide price. I'll source the parts but I need an honest reliable old school mech as near to Luton as possible preferably in Luton. Many thanks.
