Kudos to you for trying this.

I'm too much of a wimp and opted for buying one from a rebuilder and swapping out the core. Lots of little goodies and things to go wrong.

Fun fact: that special "bullet" shaped nut that holds the steering gear in place isn't 100% necessary. I was able to use regular hex bolt to ease in putting it all back together. Since you're doing the full monty though, I would probably opt to grind down the bolt into the bullet.

If you do, I bought my box from these guys:

https://www.carsteering.com/

Not only do they send you a nice and shiny box, they'll also send you a free return label so you don't have to pay the shipping costs for the core return!

Make sure you carefully remove the hose fittings from the old box onto the new one. I had my high pressure one break when torquing down. Made me super angry and had to go to a salvage yard. Guy was nice enough to give me a new one for free saving me from having to wait for a new one from the fatherland.

Has anyone else used them or have you had issues with your replacement? From what i read on here C&M was the 'go to' for remans. CarSteering seems much better priced.

I've used them and no I haven't had any issues. I daily drive my 380sl and have put on about 3k mile since replacement back in December.

Play is exactly one inch at the wheel after I renewed all of my steering components from coupler all the way down to tie rods.

I failed in my efforts to reduce the size of the steering box rebuild and reseal FSM article.

So I uploaded it to megaupload. Hope this links stays put for people in the future: https://megaupload.nz/V9Qav8X2m8/46-220_pdf

I took a look at the carsteering.com website. Their price is definitely attractive but I am always concerned when a company does not supply an actual physical address on their site. Maybe I missed it? Their description of the rebuild process is impressive. My knowledge of C&M came from a local MB trained indie mechanic that has replaced dozens of steering boxes without any issues. As I mentioned in another post that to the best of my knowledge C&M only refurbishes Mercedes steering boxes. It appears carsteering.com provides steering boxes and rack&pinion systems for nearly every make and model of passenger automobiles. So my question is "who are these guys"? As they state being a wholesaler maybe they broker all these parts from other vendors? Maybe C&M is a supplier to carsteering.com? That would be a wonderful find if true. Worth investigating, but if they actually rebuild every steering box for all the makes and models on their website they are really one giant operation. Just my observation and opinion. Mike

Weird, it let me download immediately without any login prompt.

Can anyone else confirm? I might just make a public file on some FTP I have access to.

I have no idea if C&M sells their products on that site. I'll be honest, a lot of my repairs happen to go to the lowest bidder on parts for obvious reasons. C&M probably does a stand up job, but I can't pay Gucci parts prices for rebuilds. I very rarely buy OEM products as well.

Car Steering was super attractive to me because they had a return label. Meaning zero costs to ship the box back to them. That's significant because a steering box weighs a ton.

So far, the steering box has done its job admirably. No leaks and is well within spec. I'm happy to be the guinea pig for the morbidly curious

If it helps, the free return label for my core return had this address on it:

Car Steering
1261 Aviation BLVD
Hebron KY 41048

MU can sometimes throw popups and be misleading.

I cannot get the file to shrink below 2.7mb which is .8mb larger than it can be for posting on as an attachment so here is a link for anyone needing 46-220
