W126 steering box questions
 

Two questions about the steering box on my 91 300SE:

1) Where is the hole through which a pin is set to center the steering for a wheel alignment? If the location is shown in the CD manual, I would appreciate a reference or path as I can't find it.

2) There seems to be a leak starting between the body of the steering box and the bottom piece that houses the seal next to the pitman arm. It isn't a drip, just some seepage at this point. Should I be concerned or should I wait for it to get worse?

Thanks,

seep from steering box what to do
 

Why wait for it to get worse? Some preventive maintenance will fix it now. Change the power steering oil. Add a small amount of leak stopper power steering oil from the parts houses.
or,
My favorite remedy for seals starting to seep is Marvel Mystery Oil, and use about 1 ounce in the power steering reservoir.

There is a 12MM(head) bolt at the bottom of the gear box. The special tool is the same sized bolt with a point that you scew into the hole where you removed it from. The steering has to be centered to install the tool.

I just got my steering box replaced (finally!!) and I'm kicking myself for waiting so long. I almost want to send my mechanic a thank-you note! My Benz now wants to cruise at 75+ ALL THE TIME now... We took her out for a 200 mile drive last night, and I had her up to 85+ a couple times. Still got 24 mpg including sitting in stopped traffic for 5 miles, and a week of two-mile short trips. I'm going to watch my mileage because all the sloppiness in the front suspension couldn't have helped fuel economy.
