Power steering rack - fluid is coming through - Benzworld.org

Hi,

I have seen a lot of messages about leaking steering system. I located mine and it is under the car in so called steering rack. There are two 'pumps"? Or actually I dont know what they are. Could someone help out a little bit. The two lines (metal hoses) are obviously output and input . I think both are leaking. Is there a way to tighten them? They have star looking "bolt" in the end where hoses comes/goes.

do a search on steering rack leak.
Lots of info on this.

I had my leak fixed by replacing the o rings.

allright. yeah it looks like lot of people have similar kind of issues with ML's. Did you have the leak in power steering rack? How much was the fixing work approximately?

yes you can tighten the lines. they have 2 torx heads on them. on my 99, i had a leak only when the system was under pressure. the dealer could not find it. the fluid would not come out until i parked after driving. I climbed under the vehicle and tightend the torx bolts on the rack----no more problem[:D]

What sort of tool you used for them (is it a wrench)? It is still kind of hard area to work (lack of space...)

I assume from this question you are not a strong DIY guy.

I do not recommend you attempt this repair yourself.
Bite the bullet and take it to a shop

I was just wondering that it is not a torx head I have ever seen. It must need a strong arm to loose or tighten it...

Sorry, it was wrong of me to assume that....
Anyway, I see from your other post you've changed your own Crankshaft sensor. This should be a DIY if you can manage, but usually the fix involves removing the lines and replacing the rubber orings with neoprene ones.

I could'nt get the nuts to budge - the tech at the dealer used a really long cheater bar and it took all his might to get it loose. He had special tools too...

Which is why I think the standard fix at the dealer is to replace the entire steering rack...

Which is also why I don't recommend this as a DIY

Good luck

allright. Thanks for the ideas. I will try it out tonight and if cant do will take it to somewhere. Hopefully it is only those O-rings...It sounds like it but never know...
