Shaking Disco mk1 1997

Sounds a lot like the swivel pre-load to me.
There are shims under the top swivel pin. The number (and hence thickness) the of shims needs reducing as the swivel bearings wear.
It's not a particularly difficult job, if you have a manual check in there for swivel pre-load I'm sure that it will be covered.
PM if you need anymore help.

thanks Andy I will take a look at that.
Guardian.:
i had same symptom on both my defender and disco and both times it was shot bushes in the radius arms, first time on defender i spent about a grand changing everything we could think off eventually i changed them cause i had nothing else left to change and that was it sorted.
disco started doing it about 2 months ago, sent it in to my mate, new radius arm bushes, sorted!, its the ones on the axle end, not so much the chassis end.
Xtremeteam:
try changing the radious arm bushes & the panhard rod bushes :wink:

can be difficult to find , as said sounds like swivell pre loads. quite easy to check using fishing weighing scales. what s/damper did you replace it with. i once fitted an armstrong and it made things worst. to the point it nearly put me in a hedge. returned that and fitted a de carbon gas.improved no end. i changed the radious arm bushes too and panhard rod bushes. another thing that improved it was replacing the front s/absorbers. something else that also helped was to take out a bit of the free play in the s/box, carefull though easy to over do it and make the steering tight and cause excessive wear on the box, good luck. alan.....

i have exactly the same problem :( ..... been tracing it for a while now ( 6 months ) to begin with it felt like it was coming from the rear but convinced its the front......
i have rebuilt both prop shafts.....both front bearings all 4 wheels balanced and more.
yesterday i took the swivel pin out on the front nearside to have a look. well there were no shims there. so i had a look at the offside and there were 3 shims. i wipped on out and put it all back together..... it did feel better for about 15 miles. now im back to where i was......
so im gonna change the swivel bearings and set the preload and then go from there........
just hope theres nothing shocking when i get around to doing it as this is my first attempt at this...... :roll:
