Severe vibration from back of car

Hi all.

For those of you familiar with all my D3 problems...

I haven't drive the car much of late. (Actually I have been in the USA for 3 weeks).

Last night coming home from dinner with friends the D3 developed this severe vibration in the rear.

Feels and sounds like you're driving over marks in the road left by tracked vehicles.

Comes in around 50 - 70 KPH.

ANh clues?

The car has had a new rear diff and tranny rebuild in the last 11,000 K.

Cheers

Mark T

P.S. Came across a D3 owner in New York. (Well LR3 owner) He had a sign on the back window that read:


"90% of all Land Rovers ever made are still on the road. The other 10% made it home!"

Binding EPB shoe on one of the rear brakes?

Swinging weight thingies are stuck?

Harmonic dampers - they avoid resonances and frequencies and make the D3/4/RRS smoooooth as silk...

They are also carefully designed to get in the way of the wires for the towbar electrical connections Laughing

I still think the OP has a binding EPB shoe though Laughing

Yeah, I found it, and also found that it is was in the way, when I was fitting the towing electrics...!

Or that the calipers have partly seized on (had 3 out of 4 on mine and 1 on Swmbo's car). Bad vibration one symptom, check carefully for hot wheel.

EPB or brake pads binding would be my guess. Have you had EPB adusted or the pads changed recently?

Well the noise comes and goes.

Had the brake EPB unit replaced and shoes adjusted at last service.

The wheel temps seem normal on both sides.

Starting to think it might be tyre issues.

The car has Pirelli Scorpion ATRs on it and they have done around 35,000 k .

The dealer service manager asked if the tyres have feathered edges.. a quick check today and they look OK.

But I suddenly realised today that the sound is a lot like the noise of the knobby tyres on my bike.

I am wondering if it is a harmonics problem when both tyres get "in phase" as it were. A corner or two and the noise goes away.

Anyhow, I'll get under the old girl tomorrow and see if her balls are seized or can swing freely.

Cheers

I had a problem on my wifes Grand cherokee a while back. There was a hell of a vibration and it felt as if the wheels wanted to go in different directions. it was so bad she refused to drive it because it didnt feal safe.

I had all 4 wheels balanced just to see if that helped, and it solved the problem completly. May be its that simple Question Thumbs Up

my monies on EPB shoes having been over adjusted, had exactly the same vibration when comin back from south of france the year before last, fully laddened so well up to the max gross vehicle weight, a key to this is your comment "comin back from dinner with some friends" I assume yer a 7 seater Thumbs Up

Only did the vibration under heavy load conditions, best thing to do is get 5 or 7 people in the vehicle and then see whether it replicates the same vibration, pull over and then feel the wheel hub, that will indicate which side is binding or you can visually check to see whether the hub has gone a dark reddish colour to show its been cookin Thumbs Up
