Knocking sound

[yellowpinky]

I have recently been hearing a knocking noise in my van. It speeds up as the vehicle increases speed but does not make the sound over about 10 MPH. It seems to be coming from the front end, you can actually feel it in the passager side foot well. I have the ford vented disc brakes fitted. Any suggestions welcome.<br><br>

You need to check urgently if the wheels and/or hubs are loose! I wouldn't drive it any distance until you are absolutely sure about this.
However - it could be something very innocent - such as exhaust bumping against the body or chassis - and if it's only happening up to 10 mph - does this coincide with the van being run in 1st gear ? In which case - may be a gearbox problem ? I'm assuming it's not big-ends knocking in the engine?

I know that it sounds obvious, but take a good look at all suspension components. Even if it sounds as though it's coming from one area, it could be from somewhere else entirely. Feeling it through the passenger side does suggest nearside.

As bmc above, check it before driving. Exhaust a definite possibility. Could also be damper, tie rod, callipers, etc.

Strange it stops at 10 MPH I,ve had similar with a chipped tooth on the first gear cluster.
Do a 'spanner check underneath front to back not forgeting the propshaft including front and rear UJs and fixing boltss.
As an aside I had a tinkling scraping noise the other day, looked underneath to see my timing light dangling under the car, those bl**dy stupid timing marks.

Some of the Ford disc kits require a spacer for the wheel to clear the caliper. They are therefore extremely close to the inside of the wheel when operating correctly and the calipers rely on smooth operation to centre themselves. It could be that catching at low speed after braking and then being knocked free by the additional speed and inertia of the wheel.
