As per the title I am experiencing a juddering from the front end under acceleration and deceleration, the front wheels are balanced and a new dual mass flywheel was fitted at around 80k.

It's an L&K 2.0TDI that's done about 115k now.

There is no discernible rumbling/clicking/grinding from the front wheels on full left/right lock forwards or in reverse which makes me think it could be an inner CV on the way out. I can't see any evidence of damaged CV boots either.

Do these cars have any kind of drive shaft dampening on them?

The brake discs aren't warped either, it brakes nice and straight and there is no wobble under hard braking.

The juddering is at it's worst when accelerating from 55-75 in 5th and 6th but its also there in 4th as well.

I am pretty sure it is getting steadily worse so a trip to the dealers is becoming inevitable unless a decent indy can do it cheaper - IF that's the problem.

If anyone can come up with some other decent suggestions I would be grateful.

If its a CV joint how much roughly will it cost to put right?

Being self employed I want it to be no more than 50p as you'd expect

This car is becoming expensive now

Im not entirely sure mate

But mine has the symptoms of a worn cv joints. Clicking on full lock in reverse.

I would say the car isn't very smooth at moving off from a standstill, there seems to be alot of vibration until the car is moving.

But im getting a rather nasty thump/click as im taking up drive from a stationary position and then a click and thumping/lurchin as i let off the throttle and go onto the over run in 1st and 2nd.

Do you find any similar symptoms as to what i've just described?

Then again there's no DMF judder as mine was replaced at 108k and im now on 141k.

Worn engine mounts or MAF starting to go?

I was wondering about the engine mounts as it goes, there is a lot of what is termed NHV (Noise, Vibration and Harshness) especially when the engine is under full load. This makes sense as the problem is at its worst accelerating in higher gears.

Browny - I would get your car looked at ASAP, if a CV pops it will leave you dead in the water as all of the drive will be sent down the disconnected drive shaft. I know as I had one go bang on my old Primera.

I have no lurching or juddering when pulling away although there is a dull knocking from underneath the car when lifting off after accelerating - once again it could be a duff mount.

Obviously there are two large mounts either side of the engine and I am presuming there is a mount or mounts at the back of the engine somewhere?

Major job to replace them?

Cheers Ken, I'll give the MAF a clean as a precaution, never been touched as far as I know, I'll bet the EGR system is pretty gunked up by now as well

I get something similar with mine, but the vibration comes and goes, so proves hard to pin it down.

Wheels balanced.

Front disks and pads done.

Still does it, but I've learned to live with it and to be honest, the way the car went for two months, a slight

vibration/judder was the least of the problems !

I was told at the last service that the console bushes have split, don't know enough about suspension to

know if that would cause an intermittent judder/vibration.

I was going to try a new set of wheels, but I can't justify the cost if it isn't going to solve anything.

If I put my hand on the armrest at speed, I can feel a vibration, which would make me suspect that it may be

coming from the rear instead.

Could the rear wheels out of balance, often gets overlooked.

The juddering can get very tiresome if you are in the car for 5-6 hours a day like I am.

If money wasn't an option I would have all of the bushes replaced just to eliminate them. They must be close to knackered by now

I've replaced the front wishbones, and most of the parts, bar 4 bushes on the rear suspension and the two smaller arms.

There's a huge rubber bush in the subframe which is connected to the bottom of the gearbox via two dogbone arms in series, now this does clang when the bolt drops out! Theres a engine mount to the side of the cambelt, and i presume theres one under the battery tray ontop of the gearbox. I've yet to check under the battery though.

I dont think the cv joint is anywhere near failing at the moment, i cant decide if its a engine mount or not now. As the engine seems to sit quite tight in the engine bay.

Im just hoping its not something in the gearbox (differential), it did have a rebuild on the gears side just before i bought it at 117k...but that was for a worn 1st and 3rd gear synchro's aswell as the shafts. Due to a lack of oil.

Cheers for that, I'll have a look under the car and see what I can find.

The CV that failed on the Primera gave little warning when it went pop, there was a little bit of a grinding noise but not much else. The engine does wobble about when pushed and shoved but it might be normal as I dont have a frame of refernce really, might get it looked at soon.

I presume the work you've done on the bushes and arms has tightened the handling?

I cant really say about the handling, as i've changed that many components now at different times its hard to comment. I did notice a little difference after changing the rear anti roll bar bushes though.

Im on Eibach 30mm Springs at the moment, and i found that the rear shocks were beyond help. I replaced them with some Bilstein B4 standard length shocks, i found after that it lifted the rear end of the car up and it now feels as though it leans a bit more in corners. Which im not particulaly fond of, i must admit.

As per the title I am experiencing a juddering from the front end under acceleration and deceleration, the front wheels are balanced and a new dual mass flywheel was fitted at around 80k.

One unusual judder I had was due to the inner tip of a valve falling inside the wheel when it was replaced. The wheel balancing process always showed it balanced but when that tip moved to a new position inside the rim it was out of balance again.
