My disco2 seems to have developed a power steering problem . After about 1 hours driving it gets increasingly hard to return the steering to central position after turning left or right, almost as if the power has disappeared . After a period of rest the power returns but then goes again. Any help appreciated as usual.

 

Check inside the fluid level inside the power steering reservoir.
Also look inside to see if the plastic mesh screen is clogged up on the bottom of the reservoir.

 

Thanks Juke179r....will certainly do that
