I have a slow power steering fluid leak on the drivers side. I looked today and it seems to be coming from where the hoses from the pump connect to the rack, are there any o-rings at the end of the hoses.

Thanks, I’m gonna wipe it dry and take another look. Is there anything else in that area known to leak.

Maybe the hose part, so clean it up and take some pics to post :). Make sure it is power steering fluid. It could be something else running down the pipe.

Ok so i took another look today and it definitely looks like the leak is coming from where the (high pressure hose?) connects to the rack.

Time to change seal. I would consider changing the whole line, as it is aged, and may leak sooner or later.

The high pressure side for PS pump is a very common problem on the 210.

I don't think those are 0-rings. For sure on the 1999's they are crush washers.

Take left wheel and tie rod off, turns strut all the way to the right. Take heat shield off to prevent lacerations. Take connector off SPS valve. Clean area before braking banjo bolt loose. Most difficult part of this job is starting banjo bolt straight with seals still in place.

Thanks for the help, that thing was hell trying to remove it with tie rod still on. It took me longer to thread the bolt back then anything.

So after changing seals im still leaking fluid. Im thinking either the bolt is miss thread(looks flush) or my rack is shot.

I just rebuilt and installed my R&P on my E320 wagon after chasing leaks for a while. I changed o-rings in adjustment part of the R&P and new pressure line and crush washers on fluid lines. Did not help. Leak was at top of R&P at the car coupling connection spindle and at mid-base gasket. No leaks after repair. Good luck.

I think thats where mine is leaking from, I don’t see anything until its dripping off of the SPS valve. Did you buy a rebuilt rack or did you repair the one on your car already.

I had a bit of a journey. The initial R&P had massive leaks (not drivable) from the end gaskets showing up through the dust covers. I purchased an appropriate R&P from a used parts place off of a 1999 E430. I installed it and discovered that it had small leaks in the areas described above, I removed this R&P, had it rebuilt (the one from the E430), reinstalled it and no leaks.
