I replaced these on my BA xr6t about 60 000 ks ago as I had front end apart. Old ones seemed ok but anyway. I replaced with a pair from eBay for $28 a pair, seller told me they supplied them to some Ford dealers as there the supplier for the genuine ones....no idea how true but they looked I identical to the Ford ones.
Just wondering when I should replace again. There is a clunk in front end that's felt in steering wheel when turning or turning into a driveway actually kinda like a pop in steering wheel... From what I remember it was very very easy to press the ball joints in So hopefully the cast iron arm is not worn where the ball joint presses in.. How many times before I have to replace the whole arm?
How do I check ball joints? Should I disassemble and see if they move freely?
