Hi All,

The power steering gearbox on my 1984 300D is just leaking way too much. With almost 200,000 miles on it, the steering feels like new. I have driven a bunch of other W123s that have had sloppy steering. This weekend, I pulled a gearbox out of a W123 in a junkyard. I am planning to run this in my car while I rebuild mine. I found this article to help: http://www.davidpetryk.net/Mercedes/Steering.htm

Does anyone have any recommendations on a rebuild kit -- what to buy and where? I would hate to do all of that work and then reinstall just to find out I had used some cheap o-ring or whatever that was not up for the task.

Thanks,

Dkr.

For the reseal kit, I'd probably look at what Pelican Parts sells. That or NAPA. Matureo a member on this board, I think reseals MB gear boxes. I did rebuild one. I did get an Inch-Lb torque wrench to set the preloads. There are two preloads on a gear box. The main shaft and the sector shaft. Its the difference between sloppy and siezed up. Watch out for the recurculating balls. That unit will unwind real quick.

As I do this regularly (check my signature) drop me a line if you get stuck or want pointers.

Here's a thread by our own Stretch with more detail than the one linked to.

Don't bother with the dealer, it's too expensive on this one and unnecessary. The brand I use is Hebmuller and I wouldn't trust any other. They've never let me down with missing pieces or substandard crap.

I get mine through WorldPac, my local CarQuest guy gets them for me.
