C4 Grand Picasso - What's that noise?

Unread post by rrc102 »

Hi all,

I've got a horrible pulsing noise coming from the front offside under load. Seems linked to road speed rather than engine speed. It's had a new driveshaft on that side but I'm pretty sure there was a similar noise before it was replaced (but not so loud).

Recording below. Accelerating from standstill in first, then a change up to second.

Ideas?

Possibilities could include a warped brake disc, seized brake, worn out brake pads, wheel bearing, driveshaft bearing, cv joint, loose wheel, loose wheel hub nut, wheel rubbing against something. Does the noise change if you lightly touch the brakes or going round bends ? If you jack it up and rotate the wheel do you get the noise ? Is that wheel hot after a run ?
