This thread comes to mind.

https://www.clubtouareg.com/threads/driveshaft-center-bearing-support-looks-toast.303878/post-2210515

 

Since I've been on here I've seen the JBX bearing support recommended several times after a member installed it. That I recall I haven't read about anyone coming back to complain about it.
Of course this is for the support, not the bearing itself. If the bearing is bad that's totally different.

 

The best way to cure T-Reg drive shaft ailments is to replace center bearing with Mahle parts.

I draw a small comparison between JXB conversion and well known dog-bone insert for MQB lower rear engine/transmission support.
I'd read so many rave reviews about it so I bought one. I'd driven the GSW 4Mo 6sp for few months with it. It was fun at the beginning, and then things had gone down hill. Clunky shifts, weird noises underneath the car. After 3-4 mo. I removed it and never looked back.
034 has since redesigned the insert, and I'd read reviews about it as a better performing part. In my books of farkles.
I recon, and it is a conjecture, JXB uses higher durometer rubber in place of paper thin rubber membrane type isolator OE set up utilizes inside center bearing support. And I suspect, JXB arrangement could possibly induce new issues with drive shaft NVH, akin when using poly bushes in place of OE rubber ones. The increased NVH had happened when I performed Jimmy fix. So there is that...
I'd ended up replacing center bearing on existing OE drive shaft with great results. I used Mahle parts. They are equal to OE.

Depending on year of you T-Reg, you might have to search the web for proper part number.

Talk to me a bit more about the bearing replacement...

• Can it be done in situ?
• If the bearings still have some grease and get a fresh repack, is there a really much of a gain for doing the extra work?
• What grease is recommended for a repack?

 

What does MQB, GSW, 034 and NVH stand for?

 

I was thinking the same thing when I read that post. Why can't people just write things out and stay away from acronyms.

 

MQB is a global VW platform most of newer automobiles are based on.
GSW - Golf SportWagen.
034 is aftermarket farkles company for VW cars.
NVH - Noise Vibration Harshness.

Will you need to hold my hand while crossing your own living room?

 

Oh Snap!

 

@MidnightTouaregV8
You used to be a nice, sensitive dude... What happened? Did you age or just deal with sufficient people that you're now following in my footsteps? 🤣

 

You become who you hang out with...

 

Only if you're easily influenced.

 

You can't repack sealed bearings.
You can't replace bearing without propshaft removal and disassembly.
Even if you zip tie it the way I have (and a few others) by using a grease injector to pump additional grease into the bearing, you're just prolonging it's remaining lifespan.
Once lubrication has been lost and the balls/races sustain damage, no amount of additional grease will revert that.

 

Okay thanks. I take it you're not sold on the youtube video of a guy removing the two seals with a small flat screwdriver then repacking the bearing with his finger lol

 

If your center bearing itself isn't bad, noise/looseness, it definitely can be repacked with grease. See video below at the 2:05 mark.

 

Let's pretend that some in this discussion have a tech bone in their body. Can anyone tell me what the source of any noise/looseness would be?

 

Are you referring to the bearing or the vehicle in general?

 

Check topic title and above posts

 

I know the topic of the thread I just wanted to be sure you were referring to the same topic. Your question in post # 16 is loose and leaves it open for interpretation. It's good to be specific when asking questions.
With that said wear of the balls of the bearing can cause looseness, as well as wear in the inner and outer race.

 

I implore anyone with curious mind to crack open a failed ball bearing for damage inspection. This will no doubt open their eyes to whether a squirt or two of grease will help magically fix the pitted, galled, brinelled, fretted, or otherwise damaged balls or journals.

Cheers...

 

Not trying to speak for the group here, but I don't think anyone was suggesting repacking the bearings with fresh grease was going to magically rebuild them back to OEM.

In my case, I was inquiring because the intent is to buy more time while I source a suitable replacement. These are proving harder to find new than expected.

 

Have you checked Mahle to see if they have parts for T2-T3 Eggs?

 

Been looking for a new shaft, not new bearings. If I'm removing one already for service it's faster/easier to just replace the entire thing.

Any chance you happen to have a T3 part number available?

 

The dealership has a rebuild kit, so I'm not sure what's hard to find.

 

It's worth calling and asking about, sure, but I generally prefer to not light my money on fire unless I'm in danger of freezing to death.

 

So now, asking specifically about this wear you mention in #19 specifically, what grease do you know that will revert that?

None, unless you have some of that pixie dust mentioned in post # 27. Doubt that would work either but I've been proven wrong before.

If the bearing is bad that's totally different.

Which is why I wrote this in post # 3.

 

I acquiesce. A friendly banter could sometimes be misconstrued as pejorative expression if recipient is downtrodden.

 

With the way the worlds is spiraling I think most will feel like they're downtrodden, sadly.

 

The only true wisdom is knowing you know nothing...I take solace in it.

 

Hi Tregs,

Thanks for your posts, but what I would like to know is does anyone replaced the OEM suport by JXB?
What is your evaluation/feedback?
Does it last longer?
No problems?
Do you recomend?

 

Not sure how you missed it in a couple pages of useless bickering, but I posted a link for you.

If you search the forum you'll find a lot of threads with almost universally positive feedback.

As for lasting longer, most Touaregs are getting into the 200-300 thousand km ranges before the carrier bearing needs replaced. You'd have to wait at least that long after install to find out if they will last that long or more.

 

The diference it's not so much. It's 1/3. That was one of the reason I've asked if anyone know the durability of JXB part.

For my T is this part:

1st gen Cayenne/Touareg Driveshaft Center Support Bearing Carrier Upgrade — JXB Performance

Permanent solution to center support bearing rubber failure on the 1st gen Cayenne/Touareg. Two piece design does not require disassembly of the driveshaft.

www.jxbperformance.com

But thanks for the sugestion.

 

Note that the original part is quite different. The JXB part is made of solid rubber with honeycombs, and is not attached to the shaft, and therefore has an apparent capacity to absorb impacts and vibrations without tearing like the annular membrane of the standard part.
