Just had a mechanic replace a flex disc and carrier because i was too lazy to do it myself, he wasn't a rocket scientist either. Had to redo everything myself.

I've had my share of terrible aftermarket parts, even from reputable brands. OEM is perhaps the only guarantee of not having to do the job twice. Most of the issues my car has is related to those parts installed during the past year or so and not the old worn out stuff from 97 that was obviously...

Total Quartz 5W40 is around 14.8 cSt. But is it available in the US? This is the first oil i ever bought for my first oil change and my 1000th message on bitog is about it lol.

Being european wasn't enough here. 😅

Problem found! When i thought about giving up i decided to give the rear (new) flex disc a look which was a shot in the dark and understand how it works, then i saw this video: This is was happened to me, the driveshaft was pushing on the soft portion of the flexdisc. Decided to turn the...

I've replaced them as well. Something wrong with the u-joint is on the top of my list right now, even if it seems to move freely. Out of the hundreds of threads i've read on the internet, it looks like people experiencing the same issue had to replace the u-joint. I don't know if it's linked but...

Update: I have tried unbolting the engine mounts, trans mount and carrier, roll the car back and forth and re tighten but nothing happened. The mechanic says it could be a wheel bearing or CV axle but as i understand, a CV axle would only cause a vibration under load. There's a bit of play at...

Ok now the driveshaft is properly aligned. It made a small improvement but it's still horrible. I am really running out of ideas and thinking about selling the car.

He made a mark with a pencil and was probably sloppy when reinstalling the driveshaft. He admitted not knowing about the aforementioned marks and i showed him the picture. He told me having a lot of experience with BMWs and their driveshafts seem to have a master spline or so he told me, and he...

The mechanic acknowledged his error and is going to realign the two parts tomorrow, i'll keep you posted. A W126 owner on YT told me his driveshaft had a bad vibration and it was only off by one tooth.

I use any 2 stroke oil at 1:150 ratio, and my injectors are definitely quieter! Had to fill up two times while in spain and didn't have 2 stroke oil with me and the 2000-2500 rpm clatter under load was back until the next fill up with 1:150 2 stroke. Could have been the fuel sold at the Repsol...

But the driveshaft is always turning as long as the car is moving, i don't see how being in neutral would make it more "balanced".

That's what i am thinking indeed. There's a reason those marks exist. If i am not mistaken there are 27 splines. 360° divided by 27 means it's probably off by 13.33 degrees. Ever seen this video? Shows how sensitive driveshafts are to proper balancing.

They are new too, of poor quality but new. This whirring vibration didn't exist before i took the car to the shop to have them install the new carrier.
