My PS pump is toast, noisy and leaking. I tried emptying the system and rack, and working a little axle grease into the rack to see if I like the PS delete effect. I do not. So, will be replacing all the PS stuff when I install my E36 rack. Pelican lists, in order of decreasing cost, Genuine BMW, ZF (Germany), and Atlantic Enterprises (China?). Should I go with the ZF on the grounds that the Chinese one won't last? I have 67K on the car, so I hope to be driving it for many years.
