Re: Noise

Bearing noise would most likely be a grinding or rumbing noise, suspension tends to be knocking or squeaking. Tyres will be a whooshing roar type noise increasing with speed.
I have a 1.1 and while the engine can be loud under load I wouldn't say that its that noisy cruising along and I've not noticed a tyre noise really.
If you go on to a tyre sales site it will have a db noise rating for each tyre , compare a few, just bear in mind that db is a logarithmic scale not a linear one so every 3 decidel rise is a doubling of the sound, a variation of 1 or 2 decibels between tyres could make quite a difference but it could also be that they are getting noisier as they wear, I have continentals on mine currently which are quiet but even with Vredestien Quadracs it wasn't noisy.
Just a long shot, could it be a binding brake pad? I assume you would notice this from the braking performance but you could see if one of your wheels is a lot hotter than the others after a drive.

Re: Noise

Just for those who are interested, here's a stripped out Panda 1.1 showing the standard bulkhead insulation. Not too bad for a cheapy car

Re: Noise

Brakes with friction material only ever make a squeak or squeal. Usually they make no noise at all. Metal to metal (worn out pads) is obvious as it happens only when the pedal is pressed.

Stones trapped in caliper or splash guard scrape like the worst chalk on board noise.

Wheel bearings rumble and can sound like tyre noise. The clue is no change when the tyres are swapped about.

Engine and gearbox input (first motion) noises rise and fall with engine speed.

Everything else will be a clunking or knocking.

Re: Noise

Well I got the thermostat changed and also wire brushed the rear spring cups.
After some crust rust converter it had a few coats of stone chip.

Took the opportunity to check the wheels and they spin freely with a slight catch in the rear driver side but very little.
Wiggled all the wheels and no bearing movement either.
Guess it may be tire noise and as the tyres are passed their first flush of youth I will have a look around.
Regards

Re: Noise

My rearbearings were quiet with wheels up and no play, but after changing to winterwheels the noise was still there. New bearings and no more noise.

Re: Noise

My rears were making a heck of a racket - just like tyres on rough tarmac. There was no bearing play and no roughness that I could detect. New hubs and noise was gone.

Re: Noise

That sounds like more work then.
Will have to wait a bit so up with the radio volume.

Re: Noise

I guess they are a quick remove (rusty bolts permitting) and slip the new one on?

Re: Noise

2 easy things to check:

Is the gearbox oil at the correct level.

Is the noise the same in every gear or quieter in 4th (if quieter in 4th it is one of the gearbox shafts)

I will double check but think it's same in all gears and freewheeling out if gear.
Gearbox oil has just been changed so should be perfect.

Re: Noise

Just been out. Noise is there engine off clutch in and rolling down the hill.
Noise doesn't change with the gears, dipping clutch when driving but does change markedly with road surface.

Can't decide whether tyres or wheel bearings but as the front had to have a new one for mot I guess they could all be due a refresh.
Might consider some front tyres for a change also.
My Renault Scenic is due it's not next month so will have to wait until I know that isn't going to bankrupt me!

Cheers again for the advice

Re: Noise

Well the noise was less in the heavy rain so must be tyres. Right?

Smile Re: Noise

I run my panda on 165/65/14 tyres by Davanti.. There good in the wet and dry weather and Quite.. Look at the specs against top brands.. Recently had a tyre coudn,t be repaired, true to their word replaced the tyre for new plus fitting for 22.50.. Who else does that ? What i,m saying is look at Davanti tyres , before choosing new tyres
