Chrysler Grand Voyager Mk4 Strange Vibration Issues

[rodders27]

Hi,

 

New to this forum and new owner of a 2006 MK4 Grand Voyager. 

 

Firstly, I already love this car to bits. It has its strange ways and is not perfect, but i'm working to fix the minor issues.

 

Rear drivers electric door not operating, battery drain, handbrake performance, some minor bodywork issues. But overall these are all fixable and I got the car at a sensible price and knew about these.

 

However, I have one issue which is concerning me.

 

When cruising at around 40-45mph and low revs, roughly 1200-1700 I get a vibration from the car. It feels like a vibration or rumble, but the rev counter does not move (hunt) or lose power.

If i blip the throttle, or accelerate it goes away instantly, only happens at this speed and low revs with some peddle pressed down. If i release the throttle pedal it stops.

I thought it might be wheel balance, but there is no vibration from the steering wheel. Its a whole car vibration.

 

As I had an Audi A4 with "multicronic" before which failed completely on me, I am immediately worried its an automatic gearbox issue, but my Audi experience rev needle jumped and the Chrysler does not.

 

Has anyone experienced this before, or has any ideas before I book it into be diagnosed?

 

Thanks in advance,

Michael.

Sounds like the torque convertor.

Have you checked your gearbox fluid level? Start there before looking for a new torque converter.

Might be worth getting the gearbox serviced & having new fluids & filters & the gearbox cooler flushed.

 

As for upur other issues there's loads of videos on YouTube showing how to fix most stuff on these -you just need to remember that in the states these are called a town & country.

A battery is an essential need, everyone has a different view, mine is 80/800 on these cars - see here. Every single thing in these cars is BUS / computer run and depends on a good battery if I had your list I'd start with a good battery. For now pull your battery [no code needed for default radio] and give it a good charge, refitting will 1st run a full 1st check on the BUS and reset the computers, get a new battery if you need one. Best of luck

Thanks for all your good advice. I did indeed have a low battery, which I will take out and charge first. After this I will get the gearbox serviced and hope that resolves the issue for now.

Hi rodders27,

 

Trying to compare to an issue just come up on mine, do you get anything when you're in park/neutral and the engine is at idling speeds, or is it purely when moving?

I was just talking to an autobox specialist and he said that if you put the autobox under load in any way and the noise goes away that would point to torque converter or the flexplate having a crack/damaged.

He did this test, sat with handbrake on, put the car in drive and foot on the brake. He then lightly increased the revs to see if the noise would appear/disappear. Does this make any difference on yours if you do the same? Noise there or appears or goes away?

I agree though, a fluid change sounds a good plan too.

Check the obvious. Put the front wheels on the back, run the car and see if there is a difference.

Put the spare on each wheel at a time run the car, see if it changes anything. Be careful at speed with a space saver.

tyres usually vibrate at a certain speed. And pass through the imbalance.

When you rev the engine when moving you put whatever is vibrating under load. When you take your foot off the gas it is free to vibrate again.

Try the same speed in different gears, does it still vibrate.

Make notes of everything.

 

If the vibration occurs at the same speed. something is out of balance.

If it was a mechanical fault it would get worse the faster you go.

yep as @@blackvelvet says check the obvious, I had a rear wheel very out of balance, tyre repairer couldn't be bothered, had no steering wheel shake but did have vibration through the whole car.
