Woop woop noise!

[Dave_ST220]

After some advice on this. After fixing up the old Mk1 Mondeo I now have what I can only describe as a "woop woop" noise from the front, it is related to speed but only seems to be evident at about 20 MPH. Any slower, silent, any faster, silent. The tyres are approaching legal depth so I thought it may be them, I swapped the fronts & rears over (slightly more meat on them) but it made no difference. I've not jacked it up yet to check for any play (wheel bearing). Cornering seems to make no difference nor does been in or out of gear. Thoughts?

Not "mooseing" is it?

Nah 100% not, I came up with the anti moose pipe years ago It is 100% related to wheel speed but as to what.....
