Any news, Bantam?
I may have the same problem, hovewer, the knocking sound isn't always present - for example, I went for a ride in the morning, it's there
... Then I went for a drive in the afternoon, NOTHING
The sound however does not get louder with speed, it gets louder when I shift down a gear (say from 3rd to 2nd) and when I release the gas pedal (say 1st and 2nd gear). When I drive normally, say 60-70 on the highway, it's barely hearable.
I went to see a friend of mine and we tried to figure out, what's causing such noises, but didn't find anything - we lifted the front end, put it into gear, and so on - NOTHING (probably because when the front end was in air, the load wasn't heavy enough)... When I drove off, the knocking sound miraculously disappeared... I think the sound does not come from the engine or the suspension, gearbox or exhaust perhaps??? Well, who knew...
And to make everything even better, I couldn't take it to the garage because it's saturday. I guess I'll have to wait until monday. Darn!
If anyone of you has encountered something similar, any info would come in handy, since it's really driving me mad!
