I'm trying to get a name of the part that sits in the front of the motor. It has power steering lines running to it. It leaking out the bottom.

Erm.. Either the Power steering pump, or the hydraulic pump..
(he says guessing)

If you have already had the SLS rear suspension converted to regular dampers then you can REMOVE the hydraulic pump for the 1990 to 1994 XJ40. You need to remove the valve block and all the related hoses including blocking off the return line to the reservoir.

The 1988/89 use the pump for power assisted braking.

Thanks for your help I will just remove it then, I already converted the rear as soon as I bought it two weeks ago. Thanks again
