Hi,

Got a bizarre problem with a rumbling from the front whist driving the faster and longer I drive the car the more apparent it becomes. If I take it out of gear and coast it just a noticeable. I am becoming concerned about it but am unsure what it could be I was thinking it could be a bearing but I get no audible sound from the car squealing. I am also guessing it could be springs as the car doesn’t like rough roads it seems to worsen the issue and after reading viewtopic.php?f=1&t=4763&start=30&st=0&sk=t&sd=a
I am getting concerned. It’s a 406 HDI 2ltr 90BHP Vplate 99 with 115000 . Any ideas as to what this could be would be greatly appreciated

Thanks in advance

What about when you're cornering?

Same level of rumbling when cornering, doesn’t feel as good cornering as it used to. But it doesn’t make any noise when cornering

I was thinking wheel bearing but the noise should change as you corner as the loading changes. I think you'd better get it in the air and have a squint asap. Good luck!

The misses was having a similar problem with her BMW.
Turned out to be loose wheel nuts

Dont overlook th obvious.

Are CV joints ok? Possibly more likely to be shocks rather than springs I'd expect.
Could it be an engine mount?

Following on from munfred, get your wheels balanced; may be as simple as that

Looking under the bonnet after the mention of the engine mounts and there seems to be a lot of movement when I start the engine on the passenger side. The engine also seems to lean to the passenger side. Is there any thing I can do to confirm it’s the engine mount easily?

Thanks for all your input

Put a jack and a block of wood under your sump and see what happens when you gently raise the engine.

gearbox noise ? diff maybe , thats what my 309 sounded like a day before the diff decided to part company with the gearbox leaving via a fist sized hole it punched thro the casing

Just had a mate have a look and it the lower engine mount thats gone but a least i know what the problem is thats for all your help

Any ideas how much its going to cost me to get it replaced?

Got Peugeot to change the engine mount @ £147 which has solved some of the problems but still getting the F#@king Rumbling. It is driving me mad the car doesn’t feel right starting to think it is the wheel bearing as it does sound worse when going round corners at times (to the right only) now and still getting it on the straight .I have jacked the car up and the turned the wheel that seems to be making the noise and it doesn’t seem obvious that it is the bearing. What can I do any further advise would help, does this even sound like a bearing issue or am I barking up the wrong tree?

Stick the spare wheel on and see if there's any difference.
When you jacked the car up was the wheel binding at all when you span it?

Possibly a silly suggestion but is your exhaust touching somewhere?

All I can offer is that moden wheel bearings don't really wear out anymore so I wouldn't be looking there if it was me.

I would be thinking about gearbox oil - perhaps it's very low for some reason?

Does the front end shake a bit when accelerating?

Get it up on axle stands and see if the rumbling's there when turning the wheels by hand - or at least a roughness to the motion. Could be a stuck brake caliper...
