Propshaft compatibility
Hi all. I'm in desperate need of a new propshaft for my 2005 S320 CDI L, but I cannot source one. I have spoken to my local dealership who say the part is definitely no longer available from Mercedes, leaving me with only second hand options. 2204106906 is the part number, and there are currently none for sale that I can see here in the UK or Europe. The issue is that I need both LWB and the four bolt pattern, which seems to be incredibly rare for some reason. I can find very little information out there, but does anyone know if the propshaft from a LWB S600 with the 4 bolt pattern might be compatible? Visually, they are slightly different, with the S600 having a smaller bulge in the centre of the rear half of the shaft, but in theory if designed for the same box, the same diff, and the same length of car, is it not likely that they would fit? The centre carrier, couplings etc. are certainly the same. It wouldn't be ideal but at this point I don't actually have any options.

You don't say what the problem is with your propshaft, but in the USA, there are numerous companies who rebuild driveshafts and propshafts, or who can actually build you one from scratch.

One possibility is to ask on here and on the other forum (BenzWorld W220 forum) if anyone knows of a driveline specialist anywhere within a reasonable distance who might can help. Or if anyone knows of a salvage yard within a reasonable distance who might have a shaft. You need to see what other models and years use the same shaft...

Just digging this one up again on the off chance that someone with knowledge sees! Still haven't been able to source the correct part, and no local prop specialists seem to want to take on the job.

I've never ordered from this place, so use your own judgment, etc. Good luck.

There are shops that specialize in restoring vehicles where there are no spare parts available ( e.g., pre-war Bugatti, Cord, Duesenberg, etc., etc.) In your case, they might cut off the worn splines, machine new ones, and weld them onto the prop-shaft. Or, they might brush-plate nickle or hard chrome onto the worn splines to build them back up to a usable size. The point is, there is virtually nothing that can't be repaired or replaced - you just have to find a specialist who will do what you need done at a price that you are willing to pay.
Or, you might just need to find what you need in another market - such as finding someone in the USA who can supply what you need, and is willing to assist you with the hassle of international shipping and customs.
Good luck! Let us know if you find an answer...

Still absolutely no luck at all on this one! No replacement parts on the market and no local shops want to take on the job. The vibration is driving me insane.
I'm now looking at plan C, which is a sort of temporary solution and last resort. Loctite 660 Liquid Metal and similar claim to be designed for use on worn splines as a way of filling any small gaps, so I'm going to give something like this a go. There are a few products on the market that do seem to have the required strength, but if anyone has any recommendations on anything seriously strong then I'm all ears.
I'll drop the rear half out, clean up the splines, apply the adhesive/epoxy, reinstall the shaft, and then see where we're at after it's cured.

Usually, the parts are splined for a reason, almost always to allow slight movement between the parts. If you bond them together, you might discover that you have ruined some major assemblies.
If you are completely out of options, there is one more possible repair. Electroplating parts is not rocket science, and nickle might work well. You can plate in a bath, which will require some support fixtures - like nailed-together timbers. If you use brush-plating, you can probably do without the supports, but be prepared to spend a lot of time brushing on the nickle.
