I just had the prop-shaft bearing mount failure on my 2010 Touareg with 77,000 miles on it. As soon as I heard the driveshaft thumping around, I knew that's what it was. I ended up limping back home at around 25mph on back roads in order to keep the driveshaft from banging around.

So far, it looks like my options are to either get the Vortex/EPS 2-piece bearing mount for around $380 (easy install..30min or so), or get the complete OEM bearing/mount assembly off of RockAuto or any other auto parts store for around $80.....but it involves pulling the driveshaft out to replace.

I love wrenching on my own cars, so pulling the driveshaft doesn't really bother me. Is there any reason to spend the extra money on the 2-piece Vertex mount vs. just spending $80 on a complete new OEM assembly?

Any info/help/advice would be greatly appreciated!!! Thanks!!!!

Both methods have been tested and proven to work.

I would go the Vortex only because then I could easily go under the car and do it all myself. Others prefer to replace the bearing (which saves money but costs time).

Which ever method makes you feel the most comfortable is the right way for you to go.

Is it true that if I just replace the bearing assembly, I will have to have the entire driveshaft re-balanced? I would think that as long as you mark everything and put it back the exact same way, it shouldn't' affect the balance much...but maybe I'm wrong.

If I have to spend $100 to have the shaft balanced on top of the $80 bearing, and spending all the time to pull the driveshaft....maybe I'm better off with just doing the Vertex 2-piece mount?

Does the driveshaft need to be balanced after the new oem bearing assembly is installed?

Thanks!!

We have some good threads on this. If you mark the existing shaft and take it apart and reassemble it correctly, you will not have to re-balance.

However after reading thru all those procedures and thinking it over, I am going to go Vortex when the time comes.

Yeah, I think you are right. For the time it's going to take me to pull the drive shaft, pull it all part, put the new bearing on it, reinstall it....and then cross my fingers that it doesn't vibrate......I'm probably better off just spending $375 to install the Vertex kit, and be done with it in 30min. Plus with the Vertex kit, I don't have to "hope" that I don't end up with driveshaft vibration when I'm done, and have to pull it all out again.

If you do opt for the vertex route, be sure that the bearing is still in good shape. Mine is still together, but my bearing was pretty much totally dry. I've tried repacking it, but I'm fairly sure it's toast (lots of play, vibration at certain speeds, etc.).

I'll be going with a new factory mount & bearing in the near future (eyeing up http://www.amazon.com/Dorman-934-703-Center-Support-Bearing/dp/B00GHT7A6U ). It's obviously failure prone down the road, but I have the resources to replace it, and I need a new bearing. After seeing the shape my old bearing is in, I'm not sure it's worth spending any time or money on a "better" solution that utilizes a factory-style bearing. Plus I'll have an opportunity to inspect the CV joint when its apart.

Well, I went ahead an ordered the Vertex mount. I didn't want to risk pulling the driveshaft apart, and then having to do it all again if the thing vibrated and I had to get it balanced.

I cant' believe that VW did not have a recall on these things.......failing at under 80,000 miles?? Some people have had them fail as soon as 60,000 miles? Why would you NOT have a recall on them and replace them with a better design? :confused:

I haven't been able to find any information about whether the OEM VW replacement driveshafts are the same old design prone to failure, or if they have been redesigned. I'm inclined to think the former, since VW hasn't really acknowledged an issue with these.

People have been saying the self-same thing for years.

Just get used to the fact VW don't give a sh!t about you or anyone else.

Brand new shafts from VW fail just the same - 60K/5yrs or thereabouts - as the originals.

That's horrible.....talk about a badly engineered part. I wonder how they got out of recalling that part?? The bad thing is that when it goes, it darn near leaves you stranded...unless you are somewhere where you can crawl all the way home and 25mph.

I hope the Vortex mount I ordered get everything up and running again. It sounds like it also comes with a new rubber coupler, I'm assuming I should install that also? OR leave the OEM one in there for now?

I choose to keep my OEM flex disk when I installed the Vertex drive line bushing...after I pulled the flex disk to install the new one they (Vertex) sent me. The new one didn't fit right and looked "cheaper." Also the OEM one had no wear and still was soft... had the new one fit correctly I would have used it, but was frustrated with it and threw it out.

Word of advise: When you grease the old bearing (please do, two seals remove both to pack) clean the outside housing so that no grease is on it. The Vertex clamps to this and the presence of any grease will result in slipping / noise.

The vertex disc will give you a little smoother feel than the stiffer OEM one.

Probably too late, but there is the $10 option.

I have 5k on it and it's rock solid.
5/8" hose, cut into 1" lengths, and zip ties.
If it wasn't an issue of being stranded out in the middle of nowhere if your fix failed, I would give it a try. We do a lot of camping and hiking on the weekends.....amd if a ziptie broke and all of those hose pieces flew apart, it would cost me a fortune to get the car towed home. The fact that you are limited to 25mph if that mount breaks makes it a pretty critical piece. Great idea, but I think the $375 for the Vertex mount is worth the money....reliability, and piece of mind.

If this wasn't a daily driver, I would definitely give it a try!!

I hear you. It's my daily driver too. I have more hose, zip ties and sharp knife in the back for emergency roadside repairs. Took me 2 hours the first time, having to cut out the old rubber. Should only take a few minutes if I have to do it again.
Nice write-up here with better pics:
Cardan Shaft? - Rennlist Discussion Forums

I'm sure others in clubtouareg are running this set up too.

I admire your unflagging confidence in that fix-- and that's not sarcasm. But I'm more concerned about that bearing seizing up in the middle of nowhere than the rubber surround failing... especially considering the ease of the rubber fix as you just demonstrated.

The mount itself doesn't break, only the thinner part of the rubber tears.

The ties won't break and the hoses won't fly out.

It's a perfectly good fix even if it doesn't look pretty!

Someone did the best part of 40K on that fix and the Viagra fix works on similar lines with, on my old T1, 30K on it now.

The bearing itself has only been reported as an issue on a couple of cars. Repacked with grease it's good to go again.
