when I am coasting (or not accelerating) there is a funny noise coming from the front of my car - sounds like its from the wheels or the suspension...

any ideas?

Cheers

i have the same noise at the same time on an auto.
its when i'm near traffic lights or am under say 30mph.
i think it's a bearing on mine.

Would a bearing make a noise at faster speeds too? it doesn't matter what speed I am going it still makes the noise...

...if anything its quieter at higher speeds too...

if you jack the car up by the subframe under the drive shaft can this eventualy lead to this problem?
i've had my car on jacks alot recently due to brake problems.
my car in stop start traffic is really bad now but on a straight open road its almost silent.

i cannot say without looking but if the subframe is in bad shape from lot's of jacking then it would effect the lower arm first i would presume?,the cause would be pretty obvious best thing you can do is have a good look,jack up and take the wheels off,obvious signs would be shiny bare metal on the driveshaft/subframe.other than that pop the bonnet and inspect your engine mounts for perishing,give the engine a wobble and see which ones move.

my engine had dropped within the subframe due to a knackered engine mount and consiquently the driveshaft began to catch on the subframe.

I had something similar when i installed my 1300 into my mini. It was the crank harmonic balancer or pulley that was grinding against the engine mount. I will see if i can find a link to the forum topic. To fix it i loosened engine mount and re tightened it with the engine lifted or moved slightly ( this is how i remember it anyway)

Hi the front sub frame is perfect so any damage would be very light warping or bending from jacking. No bare metal on the drive shaft. (or anywhere obvious and external) After half hour of driving all noise goes away. Ran the car all over the place for our club meet last night and after it was nicely warmed up it ran fine. So i will check all the above. A member of our club thinks it's the drivers CV joint. So will do yet another inspection this weekend.
Also know of one more mini with the same symptoms so will update on here if we fix either.
