My 1998 Discovery 300Tdi seems to wander, so I have to keep correcting the line. It feels like there’s very little resistance either side from the centre position of the steering. Also, when going around a bend, it feels like far more input needs to go into the steering to get it going straight again, compared to the input needed to get it around the bend in the first place.
When driving, it feels as if there is excess play at the wheels. However, when stationary, I can see that this isn’t the case – wiggle the steering and the wheels react.
I’ve replaced dampers and springs with an Old Man Emu two-inch lift, fitted Polybushes all round, fitted a brand-new steering box and replaced the rear wheel bearings. I’ve had a four-wheel alignment check, had the wheels balanced, fitted new tyres, and checked the track rod ends and drop arm ball joints.
I’ve put 30mm wheel spacers on and this has helped a bit. It’s better to drive, but the problem persists.

This really is quite simple – the two-inch lift is causing all your problems. When Land Rover designed the Discovery (and all other vehicles, for that matter) it set the steering geometry to the exact settings required for the best of handling and tyre wear in all driving conditions.
Obviously, there is some compromise because the Land Rover is such a versatile vehicle and uses a lot of different terrains. Part and parcel of this steering geometry set-up is the castor angle (ie, the angle at which the front steering pins are set to help the steering to self-centre). You’ve fitted a 2in lift and have moved the castor angle out of factory limits – that’s why the steering feels like it does.
You can rectify this by fitting castor correction bushes or radius arms or, failing that, put the vehicle back to standard height – which will make your driving seat a far safer place to be.
