One of the more common areas for fluid leaks is the power steering system. In rare instances it is simply the hose from the fluid reservoir to the Steering Box. More often it is a combination of the other two hoses and/or the seals in the bottom of the Box itself. The fluid will saturate the Panhard Rod Bushings and cause them to fail in proper lateral location of the front differential.--usually felt as a "vagueness" in road feel that gets worse over time.
Land Rover issued a TSB (Technical Service Bulletin) to address steering "shimmy". The root cause is Panhard Rod and Radius Arm bushings that need to be replaced. This eliminates the free-play in the front axle housings-lateral location.
The steering system requires sound tie-rod ends to maintain the correct tracking ability on and off road. Check yours with a pair of Channel Locks--one jaw on the nut--the other on the top of the rod body. Squeeze-- and look for "compressibility". You'll know when they are not long for this world. When re-newing these parts, don't be alarmed in not being able to remove them from the drag-link. Frequently-- this also has to be replaced as the tie-rods are frozen from corrosion and won't budge. You won't be able to do a proper front-end alignment without this adjustability.
