sha-a-a-a-a-a-k-k-k-k-k-ing!

When I bought my Discovery abount 6 months ago, there were recently 4 new tires (Roadian Nexen) fitted which are a bit of a cross between offroad tires and normal road tires.

Yesterday morning, I had a 4 wintertyres (Continental, these are not suitable for off the road, but only for usage on the normal road) fitted (on Vogue-alloys).

We took off yesterday afternoon via the motorway and had cruised at about 75mph for aro. 40 miles when we hit a bump in the road and the whole front-drivetrain started shaking so badly we had to stop the car and it would not stop shaking before we had almost come to a standstill.

We were of course scared by this and did not want to drive any further so we rang the ANWB (Dutch version of the AA [is it called that in the UK?]). They were there in half an hour, but could not find anything strange so we tried whether we could still drive the car and this worked.

We decided to give it another go and we did another 30 miles before we hit another bump and the shaking started all over again!

We called the ANWB again and another bloke showed up who took a lot of time to try and find an error but could not find anything wrong with the car. We took a ride with this man to see whether we could reproduce the shaking and yes, this worked. He experienced it, he told us he had never had a problem like this before and alas did not know what to do about it.

They towed our car and gave us a replacement vehicle in order to get to our destination.

Our Discovery will be towed to my 4x4 specialist next Monday and I hope they can find anything wrong with it!

The only sensible thing that the AA-guy could tell us was that is might be possible that the shaking was there before, only that the car was not sensible enough for it cause of the 'offroad-tires' and that with the new tires, it was/is more sensible to it.

Can anyone make anything of this? I know it sounds very vague, but the shaking was actually somewhat terrifying, the steeringswheel was shaking so badly you could hardly hold it straight with 2 hands...

I hope that none of you will have to experience this at 75mph!

this is a common problem try this link Wheel_wobble
the swivels would be the first place to start

Yes! I agree, some good advice there, but as you have only just experienced this problem after having new tyres and wheels fitted, may I suggest you check the tyre pressures, some 'tyre experts' insist on pumping up new tyres to 40psi and beyond, worth a check.

Sounds like over-inflated tyres (possibly poorly balanced but as it is not happening all the time I think not) made worse by a knackered steering damper to me.

Hi there, this shaking over bumps is a common and well-known problem. It can be cured by carious things whi I list now:

1. Check to ensure the tyre pressures are correct front - 2 atmos, rear 2.5 atmos;

2. Panhard bushes are worn - replace them cheaply and easily;

3. Incorrect tension of the swivel bearings or worn out bearings;

4. Worn out steering damper;


Check the cheap things first numbers 1 & 2.

Good luck and Merry Christmas/Kerst

My Discovery is over at the specialist right now (not that they will do much work on it these days, but still ).

I trust that they will find the fault and will repair it (they are very entusiastic about 4x4`s and especially about landrovers).

I will keep you posted on the progress!

Tnx for the tips/tricks!

The more I read the article on the wheel wobble and the more I think about it, I do no think that this is my problem.

The wheel wobble is a nagging problem which could worsen to a point that the car is almost undriveable.

Our car was perfectly driveable until we hit a bump when all over sudden, it was not at all driveable any more. The only possible reaction was to stop, even if we wanted, we could not drive any further.

I spoke to the experts this morning (they are looking after my car) and the told me that they also found the shaking and really thought this was absolutely undriveable and found a faulty part with the steering (I have forgotten the name of it, will post it as soon as I remember it:scratching_chin: ). They have ordered a new one (will set me back about 90 GBP). This will arrive probably tomorrow and when they have changed it and it has solved the problem, they will contact me.

I am very curious as to whether this will solve the problem and am actually even more curious as to the tyre change could have caused such a problem/breakdown, but the latter will probably remain unanswered.

Hoping we will get this solved, it will take me some time to get back the trust in my Disco..... Having to stop a shaking car is no fun :mad2:

ok, the shaking appears to be over... The steeringdamper was replaced and out of the blue, the car drives better under all circumstances!

When I bought the car, I had never driver a Discovery before and only assumed that all Discoveries drove like this. But (!) after the steeringdamper has been replaced, it drives almost like a regular car.

I hit one bump driving back from the garage to home (the odd 40 miles or so) which gave a little shake on the frontaxle (or somewhere thereabouts) which got me scared, but instead of breaking out to worse, it went away. I still feel that is should not do that, but I will drive the car around a bit more to see/feel whether it is really gone.

Will keep you posted on any problems/progress...

i no what you mean about it being undriveable i have been there i feel that the main problem comes down to the swivel preload this is the first thing i would check if the preload is corect then you should not need a steering damper changing the damper covers up the problem but be carefull if the berings in the swivels are realy bad then they will fall to bits then reshiming them meaning they will need a full strip and new bearings

I had the same problem, turned out that when I changed the track rod end the offside wheel was toed in by an inch! Whoops.

I also replaced the steering damper.
