Power Steering - O-ring Replacement - Help!

Hi. I have a 2003 ML320. I just noticed that power steering fluid was on the floor of my garage. After reading through the many posts on here, I decided to investigate. I have pinpoint the problem to be the O-ring. I bought the O-ring and I have found the post for the O-ring replacement instructions from this website (THANK YOU!)....

but the big problem is: What do you use to remove the one retaining bolt? I tried a plier and then a wrench but none would work. Is there a specific tool? If so where can I buy it?

The dealer wants $250 to replace the O-ring for me!!!!! I bought the O-ring ($2.50) and MB PS ($7.45) already...

Please give me advice! Thank you!

The retaining bolt? The only bolt that holds the reservoir on is a torx. Are you talknig about the reatiner clip on the rear of the reservoir?

Just buy a good set of TORX sockets. You will need various size sockets for other DIY projects.

You need E10 torx. E stands for external/female.

Please make a note...

When you replace the existing reservoir, best to replace the reservoir as well. MB delaer price about USD$40. Full dealer parts: new reservoir, o-ring, c-clip, and (2) bottle MB steering oil.

The air thru the system has already blown out a small nylon screen in your existing reservoir.

Your will need #10 torx, a screwdriver (to pop the c-clip), and best a "turkey baster" (to remove the old fluid), and a flashlight.

You also need a jack, and jack stands: which are used in the CRITICAL part of the process which is to bleed the system (WITHOUT THE ENGINE ON - ENGINE OFF PERIOD before your finish up) with the front in the air, turning lock-to-lock to bleed the air and air bubbles in the system.

Do a forum search and you will find in the past 2 weeks there has been one of our members, follwing this process all the way thru - that was TOTALLY successul in eliminating the the leak and eliminating ALL the steering noice.

Good luck !.

Hi thank you for your suggestion.

However, right now, I do not hear any steering noise problem...just leaking that I'm sure is the O-ring...so please give me your suggestion on this matter...should I go all out or just fix the o-ring for now and see what happens after?

BTW I just got this car...would someone please tell me some successful stories about their MLs as I am already getting a bit frustrated with this buy.
