Rattling Noise From My Fiesta

Recommended Posts

VERY irritating high-pitched rattle (sounds like metal rattling against metal, but am not 100%) appears to come from n/s front of the car (Ford Fiesta 1.25 petrol, mk. V, 00-02) - under where the front seat passenger's foot would be, basically - which starts when the car accelerates through 50-55mph and gets progressively louder the faster you go. Below 50mph, no noise at all. I don't think it's an engine issue because the rattle kicks in as a function of road speed, not engine speed (i.e. the rattle still starts at 50mph ish, whether the car is in fourth or fifth gear). I guess this rules out transmission for the same reason. I don't think it's the brake, because if I apply the brake while cruising above 50, the rattle doesn't stop until the speed falls below it again. I also doubt if it's a suspension problem, because there is no hint of any noise (or more than one bounce) if I press up and down on it. My guess is that some stray object has wedged itself in somewhere and is being rattled around by wind or vibration. I had a brief look in the wheel well and under the front n/s of the engine block, but can't find anything suspicious. All suggestions gratefully appreciated.

My first thought was a wheel bearing, as these are generally speed related, but im not sure a rattle acurately desribes the noise of a worn wheel bearing. A wheel bearing issue is more liky to sound like a grinding. Can you describe the noise more?

Wheel out of balance?

Does it only happen when youre driving?

That'll be the engine, luv.... :lol::lol::lol:

EDIT - After actually reading your post it sounds like you got a gerbil caught in the front wheel.

Are you missing a gerbil? If not, ask your neighbours.

The best I can describe the sound is of a hollow rattle, like that of a hailstone falling on a tin roof. It's intermittent (not continuous), in sequences of two that sound like they could be an expand-retract motion ('clunk-CLUNK ... clunk-CLUNK') and only at road speeds above 50mph. I wore out a wheel bearing on my last car and this isn't anything like the continuous grinding sound it made in its death throes. Don't think it's the cat either, because I've had one of those go and the rattle was continuous and pretty much whenever the car was in motion - not just at high speed.

I'm wondering if this could be it. Mine is the same model of car and the sound is coming from exactly where he describes. I'm going to replace the front brake pads over the weekend (probably needs new ones anyway - I've had the car just over a year and there is no record of them ever having been changed in the car's 36k mile life, even though it passed its MOT last month), and if that doesn't kill the noise then it's Nationwide Autocentre's problem.

Cheers for the tips.

Edit - inserted 'I don't think it's the cat' plus rationale.

Brake pads are the first and simplest check. The regular clunking might also point to the CV joints (the joints in the shafts that drive the wheel even though it's turning). Normally the latter shows up when putting power into the wheels whilst at full lock in either direction. If you go to a Nationwide, and it's the latter, you'll pay. Smaller, local, mechanics will be able to source reconditioned parts and don't rip you off as much as they rely more on word of mouth for new business. This is the way to go unless you're really holy about your car. Clearly, being a Fiesta driver, you aren't.

Thanks. Brake pads I have the ability and the tools to replace myself, but not major surgery such as axles and drive shafts. Will look for a local independent garage if that doesn't do the trick. Have always been satisfied with the reliability of Nationwide in the past, and so was prepared to pay a bit over the odds; but if this does turn out to be a major issue, point taken in that it makes sense to avoid the chains.

I had a similar noise to what your describing...

it sound like a heat sheild has bent to me... one that covers the gaiters probably near the hub and brakes.

hope so anyway, was a free repair on my car, just bent it back... it did haunt me for about 6 weeks thou, and I almost got rid of the car because of it, take it to a SPECIALIST and they will most likely be experienced of the common problem.

just a tip... i did, and he never charged me it was so common and a 30 second fix.

in return i took my car there for everything out of respect and his knowledge.

Operation Brake Pad had to be abandoned because it rained more or less constantly over the weekend, and there isn't enough room in the garage to do the job under cover. Am aiming for tomorrow evening if I can get away from work early enough. Watch this space...

Sounds like it could be the stone-shield cover to the brake disc. Sometimes the thin metal can get a hairline crack across part of it and rub against itself, causing a very irritating noise when at high(ish) speed or when going over bumps. I've had this a few times on my mini. To check if it's this, give the shield around the brake disc a flick or a poke - it will make a similar rattle noise if it's this.

It was the brake pad. The spring clip which holds the inner pad into the barrel of the piston on the nearside caliper was rusted to buggery. One of the three rivets which hold the clip to the back of the pad had failed completely and another was loose. Funny - the pad itself wasn't that worn, and neither were the other three (the clip on the inner pad on the offside brake caliper was fine). Replaced all four pads, took the car for a spin to the ring road (so I could get it up to a good 60mph); noise gone.
