i have experienced a clunk in a few aurion sportivo 's at my work. We have changed a couple of l/h/f struts and some have been fixed and some havent (maybe just not heard as loud once replaced). All of the front ends check out all ok and in some cases the noise is heard when the suspension movement is harsh and quick. A lot of people seem to think its the valving of the strut. The intermediate shaft issues as DJKOR points to is more at a slow speed either braking or accelerating and felt in the steering or brake pedal. i will admit that i can hear a slight knock on occasions from the l/h/f of my zr6 but haven't really worried about it.(maybe its time for some suspension mods now ????) Oh wow, I wasn't really expecting such a fast response. Excellent service :D Just under 43k on the odo. I had a read of the 'intermediate shaft issues' thread, but it didn't sound quite like what I get. Based on my interpretation of the posts, that issue seemed to be more of a feel then a sound, whilst mine doesn't have any feel associated with it, and seems to be entirely sound related (i.e. car doesn't pull to one side when it happens, no jerks on the steering wheel (well, excluding the obvious one :D), etc.) Any guess how much Fulcrum would charge to look at it, DJKOR ? At this point, I'll probably take it back where I bought it since I have a "mechanical protection plan" with them, but if Fulcrum are likely to be significantly better, I'd obviously consider taking it there instead.
