A while back I posted a thread re a knock or rattle in the front suspension mostly heard when driving slowly over uneven terrain (dirt-pot holed parking lot). Can't seem to find the post but did promise to report the diagnosis. It was the tie rod which is now being replaced. The joint at the end where it then goes up to the wheel moves about a quarter inch. I know at least one other owner said he had the same symptom so best have it checked.
Thanks,
Jim

Thanks Murphy, I've been getting a little noise that sounds like a loose fitting in the right front suspension.
I took my 335 in for a retro-fit oil cooler and had them look into this at the same time but they came up with nothing. I'll revisit this with them and give them this information.
