I have a 2000 discoII with 19000 miles. lately car seems to follow grooves in the road - bumps seem to translate to the steering wheel and sometimes change direction of car. also (this may be my imagination) the powersteering feels over assisted at times - any takers on this one?

do you have too much play in your steering that needs to be tightenned up? Are you having to constantly turn the wheel back and forth to stay in the middle of the lane?

Can you turn the wheel back and forth and it feels like there is a gap between each direction of turn where the wheel isn't doing anything?

Don't know how to fix it on the 2000 if so, but someone here probably does.

On my 91RR it is the allen bolt surrounded by a nut on the top of the steering box. Just loosen the hex nut and tighten the allen bolt. Then retighten the hex bolt. Don't overtighten.

Try your tire pressure. It could be as easy as that. If those puppies are aired up around 60-65 psi you WILL be catching grooves in the highway. I had a tire plugged once and the shop aired all the tires to 62 psi(not sure why), I drove unknowingly for about 20 miles like this. It was like driving on rock wheels. If you are familiar with I-95 up the east coast, or any other major highway for that matter, youve probably seen the middle lane has permanent tire grooves from all the big rigs that tear up and down. These would jerk me around like a carnival ride, I finally stopped, whipped out the handy pressure reader and proceeded to air em down to about 40-43 psi. Huge difference, no more lane grabbing. Try it, woulndt that be a nice cheap fix?

Chances are that tire pressure will have a significant effect on your problem. The DI is hightly sensitive to tire pressure, and I imagine that this aspect of the DII isn't much different. Another key thing to mention is that the front tires like to have less pressure than the rears, about 10 psi less. This helps tremendously. I had my wheels balanced yesterday and the shop pumped the stock michelins to 38 psi all around. My disco likes the stock pressure of about 27 front, 38 rear. CHeck your drivers door for the recommended pressure, then check your tires. You'll be amazed at the difference tire pressure makes.

Have you thought about a bad steering damper? I had one go bad on a J##p before.

I just went through the same thing on my 99 series 1 I replaced the stock steering damper with an old man emu from atlantic british and got new tires, it fixed everything.

My '93 had a bad shudder/shimmy thru the steering until I fitted a Bilstein steering damper. The high gas pressure in this unit stopped my problem almost completely although occasionally I can feel something a bit wobbly up front but it never amounts to much. My tyres are a little scalloped on the edges, which is probably what starts up the shimmy as the front end is otherwise tight as a drum re. bushes, steering box etc.
