Thread: My disco is deadly above 70

The Panhard bar bushes are good, the rear A-frame bushes are good and the rear A-frame balljoint has a small amount of play but nothing extreme. The tyres show no uneven wear to indicate misalignment issues. The Disco Sways terribly around corners, even slow corners like around a round-about and at speed it tends to jump into the opposit lanes or into the ditch, not a nice thing at all. The only thing left is the shocks, and I really think they are completely rooted, I can lean on the front right bumper and the disco drops 50mm, if I put my weight on it and bounce once I can drop it 75mm. I'm just wondering if bad shocks will make it dart side to side like it does.

Had the same problem, replaced my shocks and it improved around 90%, also found small bubble on the inside wall of my front tyre, once replaced all was good.

i had my tyres rotated this month (after a fair while) and found a bit of action at 100. I'm assuming it tyres as that is the only thing that has changed (that i know of...) and they had a fair bit of tread loss inner side, hence the rotate.

good luck.

Ditto Mr RHT - a new set of shocks is a good idea anyway. When their website is back together (At the moment there is something amiss with it) "Suspension Stuff" ( they have ebay ads too for Disco lifts/shock sets) have a good deal on generic gas shock sets - all 4 for $440 including postage to most anywhere. I had similar troubles with my RRC, and a new set of shocks/tyre re balance /rotation made a huge difference. Search the threads a bit, as there is plenty of info on the pros and cons of each brand, and even using shocks meant for other vehicles in a LR.

If you get a 50mm drop just by leaning on your vehicle I'd suggest, without even knowing your body weight, to also invest into a new set of springs when you are about to change the shock absorbers.

have your wheels balanced.......I have lost a wheel weight on mine recently, didn't know but car shook like you wouldn't believe at 101kph.

saying that I'm assuming thats what is causing it as it was driving ok before and have just noticed i have lost a wheel weight

What tyre pressures are you running on the road. Too higher pressure on the road can make treads squirm and make the car a bag of crap to drive

youre getting a combination of effects.

you probabley have a wheel out of balance that only shows up at a certain speed.

your shocks are shot

your front springs (at least) are shot.


Ive just done a disco 1 for one of the guys at work with a similar symptom set $700ish later at suspension stuff and the discos 2 inches higher and allegedly handles like a dream.

(he had sloppy wheel bearings that was the initiator of "death wobbles" when under brakes on corners)

To get it to drop 75mm as stated you'd need to be weighing about 690lb's if they are OME springs.

I'm guessing your springs are shot and likewise your shocks are probably due also.
