Clunk, Clunk!!

2003 360 spider F1. Yesterday whilst dropping from 4th to 3rd and accelerating to overtake, there was a dreadful clunk, clunk noise. Initially I thought a large stone had bounced under the car a couple of times, but it happened again when I repeated the manoeuvre later in the drive.

The car seems to be driving fine and if I change down from 4th to 3rd as I am slowing down, it changes smoothly and doesn't happen.

May not be related, but I have also noticed it is a little difficult to drive slowly in 1st or 2nd as the clutch engages and disengages producing a little bit of "kangarooing". Clutch wear was 20% last service. I guess PIS could need adjustment.

Any ideas? The car is going in later this week, so I will be able to give feedback if anyone is interested.

 

Not changed gear box oil recently and I was on a straight. I do have some play in front lower ball joints which are being replaced later this week, but I don't think it was them. The noise seemed to come from behind me (just), towards the middle and lower down.

I wondered about engine or gearbox mounts as the gear change happened fine, and there will have been more transmission movement because it was a downshift whilst accelerating. Thanks for the suggestions.

 

Well, I've taken the car in.

I explained the issue to the mechanic and I did not like the look on his face!

His expression and teeth sucking, intake of breath had way too many ££££$$$$$s attached for my liking.

We will see!
