I'm looking at purchasing my very first Land Rover, a 2002 Disco. The only issue of major concern is the way it drives. It's almost like it doesn't track straight, I'm constantly correcting right and left just to stay straight in the lane. I'm never able to achieve "straight", the corrections are constant, making the ride pretty nerve wracking. Has anyone experienced a similar issue, or does anyone have an idea what could be going on? Trying to suss out whether this issue makes or breaks the purchase. Thanks!

 

Get the alignment checked first. Make sure they shake it down to make sure everything is tight. Make sure tire pressures are good. Once alignment is true, if you have play in the steering wheel like I did recently, you can adjust the gear box ever so slightly to remove the play.

 

@quackers19 Yup have it inspected at a alignment shop, it could be as simple as all the tie rod ends could be shot, or bad tires But it could be something more.

 

A stuck or sticking brake caliper can also cause these symptoms.
If you are AND you should get a PPI, just have the shop inspect the caliper pistons and caliper bracket/guide pins for proper return.

When you test-drive this thing, at about 30 MPH take your hands off the steering wheel and apply the brake.
If the truck pulls left or right you could have a sticking caliper. Not the end of the world as far as repairs go.

Even if this turns out to be steering related (tie rods etc) or a brake problem it's not a deal breaker. GOOD LUCK!

 

Tramlining - Check alignment as others suggested - zero toe is not typically preferred because it can cause the vehicle to follow every little line in the road.
You typically want some degree of toe in or out, not zero so check that during the alignment check as well.

Tire pressures - tire wear and age as well.......
