New to D2 scene... used to earlier trucks... so looking for knowledge of PAS issues with an 04 D2. loosing a lot of fluid from what looks to be the seam where the high-pressure line port mates together to the pump body... assuming a paper gasket there. Might be the low pressure hose too as it's too wet to tell the difference at this point... gotta get some brake clean up there and inspect more. But I wanted to see thoughts on replacement and or is this a common fault?

 

Yes, hose leaks, and gasket in pump also leaks, both common problems.

 

Gasket available out of Poland for about 6 bucks, noise is due to air in the system likely. Front bearing can wear out but it takes a lot of miles.
