Identifying a noise in the van Forums

Grizzly

We've think got the added objects rattles sorted (one tip- thin freebie mouse mats make good plate separators) but we're now plagued with a high pitched squealing noise in the cab.

We can't work out exactly where it's coming from. It's related to road surface so we're pretty sure it's something rubbing and it seems to settle down on smooth roads or above certain speeds but never stops entirely. In our old vans we sometimes had noises from the furniture but this is in the cab. We don't think it is the engine. I thought it might be the concertina blinds but have tried pressing and adjusting them as we drive and have made no difference.

It has the capacity to drive us mad and we have got to fix it before we do any long drives.

Any suggestions gratefully received !

sounds like a belt squealing, lift up the bonnet and see ...best to stop first though.

My guess would be two panels maybe, certainly two items joined together, flexing and rubbing together.

Your suggestion of furniture noises is spot on I think, only it's part of the cab construction or maybe the Luton. It can be very difficult to pinpoint the source of a noise, especially a high pitched one.

We had a similar chirrup that took all the way to Italy and half way back before we even found it. It was one of the catches on the Luton locker (our is not an overcab bed) which needed adjustment.

The van flexes a little bit as you drive of course, and this catch was just rubbing enough to squeak. Problem was I thought it was on Sian's side and she was sure it was on mine. (Shall not admit who was correct.)

I've seen a motor engineer get a long mailing tube (like about two feet of loo roll inner) and stick an ear in one end. He then waved it around the engine (the cab in your case) and the tube helped isolate all the extraneous noises and focussed in on the one he wanted to find.

You would look as big a pillock as he did I'm sure, but it did seem to work as he identified the squeak in my engine that I couldn't find.

Hope this helps

Could be cab door rubber seal. try some talcum powder on it.

Is it DEFINITELY inside the van? I had a car that drove me mad and the squeal changed according to road surface, speed etc. It turned out to be the wheel rubber rubbing on something on the brake. (Not good at tech stuff, sorry so can't be more exact.) It sounded like it was under the bonnet. Joy
