    My MH is based on the very last of the X244 Ducato Maxi Chassis/Cab. I have a squealing/squeaking noise that is getting steadily worse, although it is only intermittent, coming from I think the offside front wheel.

    I don't think it's the brakes - yes, they're a common source of squeals I know, but putting the brakes on doesn't seem to affect the sound - and after a long trip all the wheels are at roughly the same temperature so I don't think it's a seized caliper.

    However steering, even if only very slightly, does affect it and makes the squeak come and go.

    Front wheel bearings I know are a common Ducato problem and I'm wondering if it could be these - has anyone had them squeaking rather than the usual rumbling noise that a failing wheel bearing makes?

    Jacking the front end up reveals that the wheel spins freely with no apparent noise and no apparent play in the bearings. It's not a suspension bush squeaking, the noise comes and goes with speed rather than lumps and bumps in the road.

    Dont know if ducato pads have spring steel squealer tags but if so then applying the brakes wont stop them squealing but slight flexing of the discs/hubs on the bearings under cornering would.

    Manual/visual inspection of the pad thickness would be worth a shot.

    Unless a bearing has seized solid it wont squeal...it will rumble.

    It's more than likely..................... a sticking caliper ......

    Yes, I had a sticking piston in a caliper which caused a squeeking noise. Freed off the piston and no more noise. I subsequently replaced both calipers. If a caliper is sticking you can expect the disk and grease cap to be abnormally hot. I would recommend popping the vehicle along to a friendly MOT garage and having the brakes tested on the rollers.

    If you have the facilities (good axle stands) jack up the MH then position the axle stands under the suspension uprights. Lower the jack so the MH is resting on its suspension. Then drive the wheels with the engine. You may be able to replicate the noise & with a helper also have a chance of discovering the source.

    If you have the Summer edition of the 3MMM's on page 188 onwards Nick Fisher has given some sound advice about all the Models of Fiat Chassis and problems that might arise during ownership. Nick is a highly respected contributor to this magazine. One area covers wheel bearings.

    I have this problem quite a lot in my Astra. The noise will start, braking doesn't affect the volume of the squeak but turning the wheel one way does. In my case it is always the brake pads not fully retracting, and is fixed by replacing the pads and cleaning up the calliper.
    Is sounds so similar, that I would get the brakes checked first.

    I've changed the front nearside wheel bearing on my X244 and the rumbling (sound and "feeling"on the steering) is quite distinct, and if you jack up your van on the suspected side, and spin the wheel by hand, I think you'll find it obvious if it's that. As others have said, caliper is more likely.

    Thanks everyone.

    Given that it's a 9 year old van that's only done 23,000 miles, it's quite possible that it's on it's original pads and the calipers have never been disturbed since it left the factory. I had to have the back brakes stripped and re-built last year due to problems with them sticking. The brakes shall be my first port of call then.......

    When my Ducato's front wheel bearing started to fail within warranty in the middle of a European trip the wheel nuts gradually worked loose and needed re-tightening at regular intervals until I could get it fixed back in the UK. Might be worth checking your nuts to see if anything's wrong. If not, it helps narrow down the possible causes.

    Well, back from the garage, slightly sticky front calipers and a wheel bearing that was starting to go was the diagnosis. I hadn't noticed the rumbling bearing, but it's certainly quieter to drive now so it was clearly going. Odd thing is that on jacking the van up the wheel span freely, with no play or noise evident.

    When the garage moved the van they thought one of the back brakes was squeaking, which they checked and adjusted. However, when I came to pick it up, I backed the van out of their yard and then pulled it straight back in again - handbrake not releasing properly. So the mechanic came out in the van for a drive with me, and of course the handbrake behaved itself perfectly............

    It continued to behave itself just fine until half a mile from home, when a sharp "crack" was heard from the back end as I slowed for a junction, the rear brakes had obviously partially engaged and were now dragging. So the garage are coming out to collect the van in the morning!

    The rear brakes on the "Maxi 18" chassis do appear to be unnecessarily complicated.

    Could also be a small stone trapped on the brake mechanism, had it happen in one of my Sunbeams.

    Yes, I've had that happen a few times on cars, where a stone gets lodged between the disc guard and the brake disc. Makes a horrendous noise! Reversing often makes the stone pop out though.

    Not that in this case, the squeal is sorted now. Now I just need to get the garage to correct whatever they've done wrong to my back brakes!

    Full marks to the garage, they picked my MH up from my house on Friday morning, dropped it back on Friday night with profuse apologies saying that they had misadjusted the handbrake on one side, now sorted and that they had stripped and cleaned both back brakes.

    Whilst it's frustrating when it happens, to my mind the mark of a good trader is how they react when there is a problem. After all, the only person who never makes a mistake is the person who never does anything!
