Does anyone have a source for a front hub bolt for a '85 300SD? I'm told by Mercedes that the part is no longer available. This is not to be confused with the lug bolts, but are the ones that hold the hub to the disc rotor. I'm betting that that driving around with only 4 of 5 hub bolts will be a bad thing, ya think?

These? http://catalog.peachparts.com/RenderScriptTemplate.epc?_cmd=epccat_VehicleAAA&cookieID=2FU0VVLUG2FU0YXR4E&yearid=1985%40%401985&makeid=MB%40%40MB%40%40X&modelid=300%2DSD%2D002%40%40300SD&catid=N%40%40Brake&mode=PA&subcatid=N1004@@Brake+Disc+Set+Screw&source=www.peachparts.com&clientid=catalog.mercedesshop

If so, although you have 5 holes present in addition to the 5 lug holes, only one per rotor is used.

I suspect it's a generic socket head cap screw. Try Fastenal; you will need to determine the diameter, length and pitch in advance.

Mercedes considers those bolts to "one time use," so it's a little strange that they would no longer be available.

No I don't think those are the same thing. I do indeed have five of these bolts and their associated holes per hub (as well as the 5 lug bolt holes). Tried Fastenal, nothing, tried my local industrial bolt supplier, nada...I'm still looking though, I think the junk yards are next but it's not like the car is going anywhere until I find one.

I've included a pictures of the little buggers, where they go, and what happens when you don't get them torqued down to spec's. Let my misery be a caution for all those who come after....!

Thats odd, I doubt MB would stop selling those.....either way, I have 5 extras in the garage attached to a hub I got from the junk yard.....I'd sell them for $5 shipped each. (to cover the hassle of retrieving/sending)

Hub is not for sale though, we'll be needing that on our project car. Someone stripped out a lug hole on the drivers side hub thats on the car. At least we have a spare!

Update: My local Mercedes service shop is the one who told me it was discontinued. In desperation I just called the Mercedes dealer across town and they found the part. Yea! I hate doing that because they always look at me like "Why are you working on our Mercedes? Philistine." Plus I'll spend more on gas getting the part that the part itself costs. Oh, well, gotta have it....

Thanks for the help, though.

Dex, I have an 85 SD parts car at the ranch if you need anything else.
