Focus TDCi noise at ~60mph - jimbo_the_jetset
We've recently bought an 03 Focus TDCi (115bhp). ~60k miles.

Having driven it a little we have noticed a low rumbling noise when the car is at approx 60mph. It makes a sound like when you go over the rumble strips at the side of the road, but the noise isn't that loud and isn't constant, it comes in 1/4 to 1/2 second regular bursts. And no, we aren't going over cats eyes or white stripes or anything silly like that.

I don't think it is related to the wheels or tracking as it is not found at any other speeds and seemed to go away when I tested it and depressed the clutch at 60mph. Therefore I am thinking engine, possibly a pump? Or the turbo whirring down? It does seem more prominant when slowing down although I have noticed it when accelerating.

Any ideas or experiences from Focus owners?

Hello

Focus's Tend to eat Wheel bearings.

Jack the offending wheel up and spin it. There should be litte or no resistance.

Please make sure you use the jack safely and do not get underneath the car.

Wheel bearing is favourite. Is it front or back noise? (hard to tell I know) does it change when you lean on the steering slightly?

Hard to say if it front or rear. Can't say I've noticed it changing much when steering, mostly noticed on motorways when slowing down in traffic. Plus my partner drives the car day to day, I only get the chance at weekends.

Are the vibrations likely to only occur at at a particular freqency at first? And therefore a particular speed?

We got a small warrenty with the car, I shall check if wheel bearings are included and get some professional investigation. Although I understand they are quite inexpensive anyway aren't they?

"Are the vibrations likely to only occur at at a particular freqency at first? And therefore a particular speed?"

Yes usually, it gets louder and extends over a wider speed range as it gets worse. Makes a kind of "throbbing" "rumbling" noise

Cheers for the info, shall post the official diagnosis once deduced

JtJ - yes please, I'd be very interested to hear the result of the diagnosis. I'd always put the noise in SWMBO's Focus down to the tyres as, at its last service, I was assured that it wasn't a wheel-bearing issue.

Yesterday, we had a knowledgable, car-rebuilding-type, enthusiastic passenger in the back who (unprompted) claimed that he could hear a wheel-bearing starting to pack up.

I'd been driving round in my Focus with what I thought was a noisy exhaust for ages. It turned out that the 'droning' noise was a faulty rear wheel bearing. The noise almost disappeared when going round left-hand bends, which pointed to the rear left bearing being the faulty one.

There's some info in my thread here : www.honestjohn.co.uk/forum/post/index.htm?t=51893

Wheel bearing has gone, if not both front.

£127 to change one, double that for two.

2nd quote £129.95 each.

3rd quote £73.95 each - Ford Rapidfit (hope they have a better part than the last one!)

Thanks for reporting back - I didn't realise the job was as expensive as that.

£127 is a bit excessive. With the right equipment, it shouldn't take more than half an hour I wouldn't have thought, unless the front bearings are more difficult to change than those in rear drums ?

I paid £18-odd for a UniPart bearing for my rear drum and changed it myself, although I had to take my drum/hub to a local mechanic because the old bearing was impossible to get out without a proper hydraulic press.

He pressed the old bearing out and new one in for me for nothing (said it took him about 2 minutes !)

Ford bearings were around double that - nearly £40 each IIRC, so £74 from RapidFit doesn't sound too bad, especially if they're usuing Ford parts.

Ford wanted around £30 labour to press the old one out and new one in, as mentioned above.

For interests sake, Rapidfit were using genuine Ford parts, although the bearings have been upgraded since the standard fit ones.

Anyhow, saga continues, Rapidfit could not fault the bearings. No play in them. And 3 people took it for test drives and could not detect the noise. Although after driving 5 mins I can still hear the noise. But if Ford say they're ok I'll put up with some noise and see how we get on, still not convinced. (other garage said they sped the wheel up, I assume on a track and detected noise which they presumed to be bearing).

Could be tyre noise, had the wheel alignment done but still noise. Rapidfit told me the front left tyre is at 6mm wear while the right is at 7mm wear. Why do people fit different tyres to the same axel, are they stupid?? (recently bought car if you did not guess).

And now I find I need new rear disc and pads because they are corroded. £205 quote from Rapidfit, er no thanks. Having never changed pads and discs on any car before I am tempted to have a go which will mean I'll be able to do it in the future and save ££££. Gotta convince the girlfriend though, she's the one behind the wheel most of the time. Anything tricky with ford disc/pad change? e.g. fiddly bits which need to go back exactly as they were, apart from the obvious of course.

Bearings - Had some go on a Honda - there was no play in them, but when the wheel was spun (jacked up) in a quiet location it was obvious there were noisier than other wheels.
I believe bearings will rumble first then develop play as they get worse. What Ford might be saying is that there not serious enough to warrant changing....but unless you are going to regularly check them for play, then get them changed IF you are sure that there is noise coming from the bearings. When jacked up the noise can only really come from Bearings, Brakes or something rubbing against brakes/Tyres.
Corrosion - You can clean corrosion easily, but if it has left lumps, pits and small chunks in the friction surfaces then get them changed (or if discs/pads are thin). Changing rears can be more fiddley than fronts as you have to be careful how you wind-in the piston without damaging the handbrake mechanism.
