Looks like my power steering pump is leaking from somewhere in the front, like front seal. Is it possible to rebuild pump (replace all seals) without special tools mentioned in Bentley?

to R&R the caps to replace the O rings.
I have done the same with a BFH and BIG screw driver but it can get a bit messy that way.

forget if the operation was successful.

I did search the archives, everybody mentioning that X shaped washers should be replaced with new ones from the dealer. Whats the part number?

My brother used to rebuild pumps and racks for a living. I've watched him rebuild pumps a few times, including making one good pump from two bad Jetta pumps. It CAN be done, but it's kinda tricky unless you know when and where to use the flatblade :)

All the other rings are easy to replace. The shaft seal requires a press. But the shaft seal doesn't usually leak.
My pressure release vavle was shot - which is not replacible. But I was able to replace all the rings.
You do need a 5/8 drag link and an impact wrench.

Just take one of the old rings to your local FLAPS and match the size in thier O ring collection.
I match to a green one that is usually used in AC systems but three of them have held fine for two years. I used a mic to match the diameter of the rubber. Bigger is not better.

I don't know how they press pulleys, but the last time I bought a rebuilt it came without a pulley. This wasn't an Audi unit. Anyway, I ended up taking it to a machine shop. They couldn't press the shaft out of the pulley and ended up drilling the shaft out. Good thing the "core charge" wasn't much.
