vibration / judder at 55 - 65 MPH - PARTS HELP

Hello All,

Happy new year to you, better late than never

As above really as driving along soon as I hit 55MPH ish I get this death judder / vibration / wobble call it what you want.

I have done a few searches and its pointing towards the Prob shaft UJ's.

What parts do I need to replace? any advice photos would be appreciated.

How do

could be a few things really, i had this and replaced the steering damper but didnt really help at all, took it to the garage and they sorted out the PRE-LOAD on the front wheels.

They just take out some shims on the ball typey things "big silver thing mo bob" just before the hubs.

could be wheel balance, tyre pressures etc.

Well what do you know sorted..

I would check your wheel bearings and swivel pins Jack it up and see if there's any play.. Worth checking tyres and wheel balance first though.

Oh yeah forgot that bit, was looking for ages trying to get hold of a hub nut spanner to tighten them all up to.

Jesus what a numpty I could be!

Only just thought, I have an odd wheel on the front near side as I only had 4 of me mud tyres.......

sounds like i need to get a replacement asap!

try this Wheel_wobble

Well i've heard of worse, like someone towing an aircraft with the gen set still plugged in lol.... what a mess that was

Cheers for the info guys

Check your panhard rod is not loose/bushes badly worn, this is the one that goes from the chassis to the axle to provide the lateral location for the axle. Also check the radius arm bushes, it could be as simple as something needs tighgtened up.

good bit of info there i have the same problem with my defender, so will check all this out cheers guys

tyre balance!

is it lifted?

I had a similar experience last year (please refer to my post titled ("shopping trolley syndrome") early 2009. It was the most horrendous experience at around 60mph. I spent hundreds of pounds on on replacing all the parts mentioned by all the other contributors together with hubs etc etc. The steering damper was replaced twice, as one was faulty, and was finally diagnosed by a new Land Rover dealership in Ipswich who used a donor vehicle in a process of elimination experience. Eventually it was found that the second leading brand steering damper was faulty and rather than damping, exaggerated lateral movement (the manufacturers subsequently advised my local garage that they sold thousands and that there would always be a number of faulty ones). Hardly satisfactory. The Land Rover chap with over thirty years experience advised that if you were to buy one Land Rover part, it should be the steering damper, which is only a a few pounds more.

The shaking/juddering was incredible and would be set off by a piece of adverse camber, bump or pot hole and would continue for as long as forward movement continued. It was the worst that the Land Rover chaps had seen. The entire vehicle would shake and it was virtually impossible to hold the steering wheel.

Please do not spend as much as I did. Try the cheapest option first.

Courage mon ami

Kind regards

I had this on my v8 at this speed as the torque converter locked the load on the engine increased and it highlighted a problem with the coil packs and leads causing a misfire and judder. not noticeable when revved freely
good luck

I once drove a disco around for nearly a year without a steering damper and didn't have any wobbles or judders. Even after hitting potholes or speedbumps at speed.

When I bought the current Disco I missed a hole in the steering damper which had lost it's fluid and seized solid:doh: .... I didn't notice any juddering and there was no difference in handling when I replaced it.

I couldn't actually tell any difference with or without the steering damper, it just felt the same.

steering damper will not correct worn steering components, they are to dampen hard knocks when off roading mostly, and the odd crater in the blackstuff when the council's get slack.

That was the point I was making. A knackered steering damper cannot be the cause of wheel wobble or juddering.

Agreed; the steering damper ordinarily would not make that much difference, but in my case, rather than damping it was exaggerating any bump/camber so would have an effect on handling.

It is probably not that, but as I said, it is relatively inexpensive.

Kind regards
