PS pump or steering box ?

On my 95 Disco, I've had hard steering for a while and with wider tires, obvious, it's worse.
It's at it's worst when the truck is not rolling and at low rpm. It gets a little better if the truck
is rolling and at higher rpms. When turning left or right the power steering pump whines.
All steering components are fine, nothing is binding. I'm fairly certain it's the ps pump. Could
it be the steering box?

Thanks

The hard steering could be caused by any number of things; excessive tire caster, mis-alignment, bad pump or steering gearbox, and tires. I would suspect the tires, alignment, and pump before the steering gear box.

Larry,
Thanks for you input. I agree with you on all. There is a caster issue, I added some rubber isolators which increase the spring height by about 1/2 an inch. The steering was hard before that. I'm running 285's which made the steering a little harder. The steering was hard, not as hard, with the stock tires. Some 20 years ago I was a mechanic. I worked mostly on Chevy’s and Fords. I would say the power steering My experience with LR's is not that extensive. I was just trying to get some feed back. I'm going to replace the ps first. I'll let you know the outcome. Again thanks.

Claudio

Hmmm, 285s with a 1/2" lift... Are the tires rubbing by any chance?

Scrover,
It’s got more then a ˝ in lift. I have OME 751’s in the front, which gave about two inch.Then I installed two rubber isolators which gave me about ˝ in more. When I installed the OME’s I had a caster issue which I resolved by installing offset radius arms. When I installed the two rubber isolators, the extra ˝ inch in height messed up my caster again.

I had to trim the rear; I had no rubbing until I removed the sway bars.

I would also check the fan belt.
