W124 driveshaft flex disc

Are meyle or febi recommendable as acceptable quality for flex disc? I know.. Mercedes parts are the best but money is tight right now.

I've heard questionable reports about both Meyle and Febi. However, my supplier sent Febi flex discs when I ordered Lemfoerder and they turned out to be made by SGF. And SGF is fine being one of the original suppliers.

So, Febi may be worth the risk.

I've not had any issues with either. I actually have 2 brand new flex discs for front and rear I just received about 2 weeks ago that are Febi. Just make sure you don't mix up the front and rear.

Febi is a known reboxer of SGF (OEM) flex disks. I've bought them for my 300SDL, 350SD, 500SL, and BMW 525i and all have been SGF disks.

Confirmed. I also have a Febi transmission mount I bought, it's still in the plastic, but my guess is that this must also be a reboxed SGF.

Be warned, just because SGF is the original OE manufacture does not mean that parts sold or re-boxed as aftermarket meet the OE specifications. I learned that at AC-Delco school years ago. They had two lines, the OE line and the aftermarket line. In some cases the parts were the same in some cases they were slightly modified mostly to make 1 part fit multiple models and reduce the part number count.

I think the best bet is when you can find aftermarket parts with the MB star ground off. But keep in mind the star may be ground off because the part was rejected by MB.

Lol. So basically, no part can be trusted.

Or for those of us who aren't snobs and don't rake in 5 figures every month, use what works just fine for everyone else globally.

I generally go by the parts significance and location. If its difficult to change buy genuine stuff. If its easy to replace and wont kill you go aftermarket.

A flex disk falls in between those areas especially if your not used to the feel of a car with a bad one.

Also remember that just because AC Delco does what they did, There parts were still superior for American cars. So choosing a good reputable name brand is a good idea.

Been ages since I replaced one of these. Which side faces front?
My recollection is the side with the writing, the "SGF" & "NR" faces the transmission.

Thx -CTH

The text "deise seite zu gelenkw" means - this side to driveline - translated to this side to driveshaft.

If I remember correctly, with Mercedes discs, the star faces the driveshaft for both front and rear discs. So with aftermarkets, it stands to reason to look for the name to be on just one side of the disc and mount accordingly. More importantly, the mounting bolt washers should not be against the yoke, but against the rubber of the disc.

Both above seem to be telling: one of them faces forward and one backward, given they are identical. That seems to fly in the face of the fiber orientation notion previous presented. I am not arguing with anyone, but I'd like you guys to work that out and present the results Right now I am thinking orientation doesn't matter until I see it from an MB document. I will be paying close attention to how the old ones are mounted when I get this over the grease pit. I need to swap the trans out of that truck currently over it first, and I am getting so old and tired ...

I follow whats written on the part literally - "this side to driveline" is enough for me to orient that side towards the driveshaft. (usually seen on soft disc as it has a specific shock absorbing purpose and wont work backwards)

On ones that dont mention any text like this - I will have to look up if they have an orientation - like some BMWs have.
