Upon removal the casing is cracked Does anyone know where I can get this replacement part even if itís a used one of do you think it could be repaired ? I am really struggling . Also does someone know where the fluid top up is located ? The hydraulic pipes all go back to a behind a box which is on the arch behind the passenger front wheel . But it seems to me that you have to take the front wheel off to get to it and remove the casing . Surely the top up isnít hidden in there ? The fluid leaking out is red like transmission or power steering fluid . There is a big cylinder tank infront of the radiator but I had always assumed this was power steering fluid . Could it also supply the levelling system aswell ? Any help appreciated
No, the power steering system is separate from the leveling system
Retract all four jacks fully.
Locate the hydraulic power unit including the pump and reservoir tank. on the 350, the pump will be located behind the axle of the front drivers wheel and accessible from beneath the vehicle. Its protected by a plastic box screwed down with self tapping screws. The reservoir is a long tank with a chrome breather cap on top containing an integrated dipstick.
Wipe off any dirt from around the breather cap. Unscrew the breather cap and remove it from the reservoir, then wipe the dipstick clean and reinsert into the tank. Remove the dipstick again and read the oil level. Proper oil level should appear in the range between the two scribed lines on the dipstick.
Add HWH Specialty hydraulic oil or Dexron-style automatic transmission fluid to the reservoir if necessary. Bring the oil level up to approximately 1 inch below the top of the reservoir.
Re-install the breather cap.
