Hello,

I am contemplating a DIY rebuild on my W124 Power Steering pump in the next month or so. The reason for the rebuild is a leak on the pump body located at the middle connecting seal, currently I am loosing about 3-4 drops with the car sitting over night, this is including a high pressure hose leak which I will probably replace at the same time.

How hard is it? The service CD's procedure is 42 pages long, do I need to disassemble the whole pump to do the seals? Is this better left to the professionals?

Please help?
