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.

I'd try either one.

Good luck!!!

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.

If they are not the same part front and rear, position would matter, but does the disc orientation matter, they seem flip-able ....

Disc orientation does matter. You see how the holes look like they are “cushioned” on one side more than the other? You want that cushioning to be oriented to accept the shock of the driveshaft decelerating.

Using the photo in post #6 which of those sides should be forward? Thanks

It's kinda like "metal fatigue". You bend a bit of metal back and forth enough and the molecules start to give way and their bonds begin to break. Put the disk on reversed and time spent in a "forward" gear pulling the fibers (tension) is now spent pushing (compression) and the material degrades faster.

These disks are a combination of rubber, metal and fiber. They only last so long. The argument over choice of vendor is about quality control procedures (did they ship crap) and quality of materials (did they build crap).

Like us, it's all going to die eventually. And like our own mortality, we have skin in the game. Hopefully we extend, not contract the car's life-span (and maybe our own) because periodically, we check up on the "wear items" and get them replaced.

(I passed a cigar shop yesterday and it left me feeling nostalgic for the days when I was enjoying those without too much guilt).
