Doin' the Rover shake.

[joe]

Has anyone seen this problem in a Range Rover?.

Well what happens is that when I get to certian speeds the Rangie gets up this little shake in the front end that soon turns into a death rattle 8O .
The stearing wheel will shake almost out of your hands! and the front right will jump up and down with grate force!.
I have had a mate drive behined me and he sez he can see the front wheels "toggle" or shake from side to side as it happens.

I have been chasing this problem for a while now and have done the following to fix it but to no avail https://www.aulro.com/afvb/ ; I have renewed the swivel bearings on both sides , I have fitted new tie rod ends , Greased and tightend wheel bearings front and rear , All bushes are polly and in good condition .

So I have done all the big things but no result! all I can do now is have the wheel alinement and balance recheked as i am a little sus of the last job done (dont you hate it when you find out they let a 17yo kid loose on your car :x ) . Has anyone got any clue as to what it could be?.
The car is unsafe to drive till this is fixed so no mud and fun for joe :evil: .

Maybe your wheel rims are buckled, have you got steelies or alloys?

This can cause what you described. Your uni's, have they been done also? Shocks are also important and if they haven't yet been replaced, I would strongly suggest you do so.

Also is there any suspension lift, anything over 30mm I have found can cause the front end to 'bump steer' causing the steering wheel to wobble especially if you hit a bump, etc....

It's a process of illimination so check everything and you should eventually find the problem.

Good luck,

A mate of mine had this same problem with his RR, and he ended up fitting this gadget off a disco that acts as some kind of inertial damper. I can see the part but I don't know what it's called. It's not the first time I've heard of this problem. Someone on here will no doubt be able to tell you exactly what to do https://www.aulro.com/afvb/

[spudboy]

Ummmm - what about your steering damper?

Had a similar situation with my old Series II and an el-cheapo "no-brand" steering damper improved it no end.

Most likely to be the panhard rod bushes. Get under the front of your vehicle and watch the panhard rod mountings at both the diff and chassis ends, whilst you (or someone else) rocks the vehicle side to side. If you see any movement in the bushes, they'll need replacement.

If it's not panhard rod bushes, it could also be lower control arm bushes.

I have the exact same problem with my rangie ATM. I seem to have fixed it now.

I have done:

Offset lower control arm bushes
new panhard bushes
steering dampner
new tie rod ends.

[sclarke]

I had a very similar problem with our Disco.
over 80kmh the front end wobbled like mad... but cornering hard stopped it...
So i thought "steering damper"
Changed to to find the same.

Looked at the panhard bushes and found them to be in great condition.
Then tried the trailing arms in the front. OK
Then tried the steering for slop. Nothing...

Took it in for a wheel balance. It was still the same....

Rotated the tyres..... its gone....
Well it does it over hard bumps... but ok..

Only thing i never checked was the Toe out. i'm still to do that.

So try rotating the tyres or another set. Weird ehh?????

[one_iota]

Mine is shaking as well. At about 100kph but not consistently.

It's shaking up the Coopers Ale in the fridge 8O .

I recently stuck the spare on the left rear after a spilt valve stem. So the imposter is going back to the rear door tomorrow.

[joe]

Thank you guys.

I have steel Sunnies and have rotated them all in turn.It made no differance :cry: .

I did not think of the uni joints so I went and had a look. the front one has a little slop (about the thickness of a credit card).

Also I have seen the tyres move from side to side when I rock the car . Its like the side walls are too week(soft).

Anyway I will let you all know how I go over the next few weeks...........if I dont go insane first https://www.aulro.com/afvb/ .

[DEFENDERZOOK]

<span style="color:blue">have you balanced the tyres......?



and have you checked the shock absorbers to see if they are working correctly.....?</span>

[JDNSW]

Some other suggestions - I may have included something you or someone else has already mentioned, if so I apologise.

Wheel bearings. Excessive caster due to worn bushes, bent components (radius arm, axle housing, chassis mount points etc) or lifted suspension.

[joe]

Yes all the things you guys have pointed to that I have not yet checked are now well and truely on my to do list for this week https://www.aulro.com/afvb/ .

And yes she has had a two(2) inch lift (the Rover not the wife :wink: ) so am treating that as sus for now. However I have all this cars history so I know lift work was done by a good company down here.

Oh well I have a good way to mix paint tins for now :oops: .

[blitz]

All I can say is I'm glad I'm not the only one, my disco series I has started doing the dame thing at about 90 km and most pronounced on a mild left hand turn?

Everything seems tight underneath, although I do have to put a new steering damper on it - but - the damper was buggered before the "death rattle" started?

When, not if, I track it down I will let you know.

Cheers Blythe

<span style="color:blue">buckled left hand front rim.....?</span>

[101RRS]

My 30yo 1 series used to do it when you went over 100kph and hit a bump - the front end was like a shopping trolly wheel doing 10kph. The problem built on itself and the only way to stop it was to brake and slow right down. It reminded me a lot of the occilations you can get in the steering of some motor bikes that end up putting you on the ground.

I never found out what it was but my series 3 only being 18yo never did it so I assumed that it was all the little bits of slack in the steering/front suspension of the series 1 combined to cause the problem - I suggest all of the above but a decent steering damper should do a lot to improve things as should tightening everything up and replacing worn stuff.

[DEFENDERZOOK]

<span style="color:blue">the preloads on the swivel hub bearings will cause these symptoms if they are too loose....</span>

[rovercare]

How are you checking the bushes. have you tried dropping out the panhard rod for a look as these generally flog the bolts aswell and are ussually the cause of bad vibration. steering dampeners simply mask the problem so its best to find the real cause. same as front control arm bushes they need more than a visual inspection, the need to be mone with a big bar or dropped out for a good look.

[joe]

Yes I have droped out panhard rod and checked all bushes as far as i can tell the polly bushes are ok so are bolts.
thanxs for the tip https://www.aulro.com/afvb/ .
so far it looks like its the wheels or the front prop shaft uni .
but just to confirm the book sez the pre load is 2.5-3 lbs is this ok? or have they made a type-o????.

[DEFENDERZOOK]

<span style="color:blue">no...thats not a typo...it sounds about right....



its just that we used to set them up a bit firmer....
but we never used the scales....just learnt to do it by feel....
and it used to make a huge difference....

i did aces up the same way if you want some feedback on any difference
it may have made....but he also fitted a new steering damper a few days earlier....

maybe you can borrow a steering damper off someone to see if it makes a difference......
that was one of the best methods of confirming our diagnosis before spending
the customers dollars on parts....



anyway....if you swap dampers and it doesnt make a difference i can guide through
the procedure of checking and adjusting the preloads if you like.....</span>

[joe]

Happy new year all.
Well thank you for the offer of a guide through on the preloads https://www.aulro.com/afvb/ as that may be the problem yet.
The new year is starting out good it seems , today I took the front prop shaft out and went for a spin only to find the judder still in play. so then I adjusted the right front tie rod out by 8 turns went for test drive and...........the judder was not so harsh.
so I think the last wheel alinement was done poorly :cry: so I will get It done again down in the city this time!.
however I will take you up on the preload guide through as I no my luck,better to have and not need than to need and not have :wink: .

Thank you all , I have lernt alot from you and now I can drive the Rangie without it acting like it wants to be entered in a rodeo 8O .

[DEFENDERZOOK]

<span style="color:blue">just let me know when are ready to do it.....</span>

In the Uk we call it death wobble. because when it does it at 130 K's it feels like you have run over the front axel and you are going to die

Caused by a combination of the follow.
Panard rods bushes, Hockey stick bushes, and steering damper

I had similar prob in my D1 at 100ks. Local Bridgestone who does one of the LR dealer's work told me that some tread patterns don't have enough variation in the design and thus wear out of round. He told me there was nothing I could do except flog off my (still very good) tyres to some poor unsuspecting soul and buy new ones.
A front to rear tyre rotation cured it immediately. Why didn't he think of that? I've since done about 2,500km's without a hint of wobble.

Your problem may be more serious Joe, but it seems a few of us at least can solve the problem simply.

Good luck,
Ian

[rangieman]

i had the wobble in a classic rangie i replaced bush.s damper, tyres and finaly front shockers problem solved try the front shocks https://www.aulro.com/afvb/

[MacMan]

I finally got she sherberts with the 90 - 100km wobble and reduced the 2mm toe out to 0mm and that has largely cured the wobbles. The only slight vibration that comes through the steering wheel now is higher in frequency and shorter in wavelength, but it is barely there at all. I might try lengthening the rear rod a quarter of a turn to see if that completely neutralises it. The tyres were scrubbing on the inside shoulder but when I measured the toe out it was still within spec. Since I've been sniffing around at second hand tyres just about all sets have one tyre that is really scrubbed on the inside - I'd love to know why the Rover front end has toe out as standard. I always thought most things had toe IN.[/b]
