110 Steering Problems

Toe in and/or caster angle. Most likely caster angle given that changing the rear tyres (and thus ride height) seemed to have mad a difference.

Thanks. The workshop manual for the 110 says that the caster angle is pre-set and cannot be adjusted - I assume therefore that I need to get the toe-in changed to accommodate the new rear tyres?

the front has Sime

Try switching the tyres around and see if this makes a difference. Yours Gmacz

Have you changed the springs for raised ones ever? That will affect the caster angle. Also knackered bushes in the front radius arms will have an effect on caster.

I think that the problem is unlikely to be castor angle - unless the bushed where the front radius rods attach to the axle are well and truly shot. Shot shock absorbers would show other symptoms, as would seized ones.

I would be looking first at tyre pressures, and then at wear or deterioration on all the bushes, especially the panhard rod bushes. And, of course check the steering for any play on drag link or tie rod ball joints. JD

is the vehicle standard height?

your description of symptoms sounds like a tracking error, but also check the condition of the steering damper (they're only about 12 quid, so if in doubt, replace it)

I tend to set the tracking as close as I can get it to parallel, and that seems to work OK.

if you've lifted the suspension more than an inch or so, this can alter the caster angle enough to give vague steering; I saw someone the other day advertising replacement swivels for lifted vehicles to restore the correct caster angle. Raising the disco's suspension by about an inch had a noticeable effect on the steering, although not enough to merit remedial action.

Thanks. The vehicle is standard height. How would I test the steering damper (I think it is fairly new so it's unlikely, but worth checking)? Also, there is an auto-levelling device fitted to the rear axle - if this wasn't working properly (I think it is but will check) could it cause this effect?

if the auto-leveller seizes it can apparently cause silly handling, dunno how it affects the steering though.

erm... steering damper... unbolt it and push it in and out. They're fairly stiff when they're working. If it pushes in and/or out quite easily it's no good.
