Re: [MBZ] Very loud knocking noise in my W123 300TD

[Max Dillon via Mercedes]

MB dealer flex discs last years and years, in my experience.  That's why I only 
buy suspension and drive line rubber from the dealer, anything else is a false 
economy.

To make one or two you'd end up costing multiples what you'd pay to just buy 
them. Liquid polyurethane makes a foam, not strong enough. Remember sheer 
strength is required here. Durometer on these must be 100 or more...
To make the volume required to make it economical you'd need to sell them which 
then involves stupid amounts of liability...
Makes $150 a decade or so seem pretty reasonable.

Are these flex disc things really that hard to reverse engineer? Buy some
proper durometer liquid rubber, put some sort of reinforcement mat in
there, fill it up, hit it with the detail sander to shake the bubbles out
(or stick it in the vacuum chamber while it sets), and voila. Do the fibers
actually attach to the steel anywhere? Why wouldn't liquid polyurethane
work?

Surely someone must have tried this. I know - stop calling you Shirley.

If one could get Febi at a good price, I suppose it's worth a try.
Sourced from Febi, made in Germany, I'd put that on one of my cars.

Seems like a lot if trouble to take. Most dealer parts are in those awesome

A lot of Lemförder stuff I've seen just has the tristar ground off of the part. 
 If it's Lemförder that's great, because I've had a heck of a time finding 
their stuff any more.  It seems like there's less and less you can find under 
their name as time goes on.

...and that would be?

Let's see when they show up if there is anything identifying who made them.

Don't get me wrong, I'm not a parts snob. If I can get a Lemförder part instead 
of the dealer's, I'll go for it - but I know what I'm getting there, too.

So many of these aftermarket and even OEMs have begun to outsource stuff that 
you're never sure where it's being made any more. Meyle, Febi and others are 
doing this, so the brand name gets diluted/diminished.

I just feel really strongly about the integrity of some parts, and when I 
replace them I want to be darned sure I'm putting a quality part in as a 
replacement, that's all.

And where has Curley been through all this? I've been missing his acerbic 
banter and Andrew abuse

Re: [MBZ] Very loud knocking noise in my W123 300TD

[Dan--- via Mercedes]

I'm all for saving a buck, without question. I also recognize when it's false 
economy.

I did flex discs, center bearing and carrier on the 300SEL.  I paid for MB flex 
discs, bearing, and a Corteco bearing carrier.  I could have saved around $150 
by going aftermarket, but looking at the available products, they were all 
manufactured in China or Taiwan and cost less than HALF what the dealer charges.

Now we all know that MB is in this thing to make money, much of which comes 
from their parts sales. That being said, part of that cost covers supplier 
vetting and guarantees the quality of said parts.

I've gone over this too many times in the past, but to reiterate: it's too, too 
easy to cut corners on rubber parts, period. Add more carbon (cheap) and less 
virgin rubber (expensive) and the physical difference is imperceptible up to a 
point. Multiply that difference to scale and now your part can be sold at a 
very nice profit while still being much cheaper than the OE part.

Mercedes flex disc: $150
Febi flex disc: $50
URO flex disc: $35

If Mercedes' markup is 40% that means their cost is around $105.  If the Febi 
or URO parts are marked up similar amounts, what does that tell you about their 
costs? That means the cost of the Febi is around $35.

Since Mercedes doesn't manufacture their parts, but the others do, they 
probably have higher fixed cost.  So if their costs are higher due to 
manufacturing overhead, they're spending a smaller percentage on materials most 
likely.

Which part do you think will have better quality materials?

When it's a critical part such as suspension, driveline or brakes, I'm not 
going cheap. Not only is it false economy, it's dangerous.

At least that's my take on the whole thing. One could argue that many people do 
it on the cheap, which is totally their choice. I want the reliability and 
peace of mind knowing that my flex disc isn't going to fail going down the 
highway a year or two after I bought it.

The impression I get when Andrew posts a question is that he already knows the 
answer or has already made up his mind about what he is going to do.  I am 
guilty of this at times when I am looking for support or agreement with 
something I have done or am going to do.  I think the difference is that I 
don't post my disagreement with list members suggestions.  One of my secrets to 
a healthy relationship (spouse in particular) is that she doesn't always need 
to know when I am right. 
Just my thoughts. I could be totally misreading Andrew, I do not know him 
outside of what he posts on this list. If nothing else his responses will 
illicit a smile on my face and a shake of my head.

AFAIK the center support bearing and front flex are original to the car.

Nothing wrong with my attitude - trying to strike a balance between
extravagance and foolish thrift.

Re: [MBZ] Very loud knocking noise in my W123 300TD

[Meade Dillon via Mercedes]

On a 124, failure of a front flex disc at speed can allow it to thrash
around (driven by the forward motion of the car via the differential) with
such violence that the airbag(s) will deploy.  The tunnel area just behind
the transmission gets beat all to hell, there are pix of the mess on Peach
Parts I think.

I think such a failure would cause similar damage on a 123, minus the
airbag deployment.

If you're God's gift to the 123 why do you ask for help? I remember a time when

Re: [MBZ] Very loud knocking noise in my W123 300TD

[Andrew Strasfogel via Mercedes]

Hey, I've driven a 123 wagon continuously since 1989 and replaced several
flex disks so I think I know what I'm doing.   How does that work for YOU,
Curt?

Remember if the flex disk fails at speed it trashes the car, this is false 
economy. Let's think back to when you ignored the list advice and replaced just 
one sphere. How that work out for you? I'll remind you, all the warnings given 
to you here came true...

Dan, the Price is $152 per from the dealer vs. $47 elsewhere for the flex
disks.  For the center assembly it's $150 vs. $27 (!!!) for Febi or Beck
Arnley (Rock Auto).  Febi is a decent brand and I am not going to keep the

Febi/Bilstein is a German company, however, that doesn't mean that's where the 
parts come from.  I've seen Febi parts that are from China and Taiwan.

Again, I understand the desire to save a buck, but this is not a place I would 
be cutting corners.

Corteco makes a very high quality center bearing carrier. The bearing "kit" is 
be sourced from the dealer, probably under $30 and contains a new boot and 
other hardware bits you won't get from a third party supplier.

Do not cheap out on rubber parts or you'll be doing this job again in under 
five years.

Flex discs from Mercedes aren't that expensive in most cases.  Front flex disc 
is around $125 from the dealer, I believe. Rear is the same.

Febi and Beck-Arnley will be cheap Chinee stuff.

Re: [MBZ] Very loud knocking noise in my W123 300TD

[Andrew Strasfogel via Mercedes]

Was diagnosed as broken center drive shaft support bracket.  Also must
replace drive shaft bearing and front and rear flex disks.  The flex disks
had been replaced with substandard brand.  Are Febi or Beck Arnley decent?
OEM bearing bracket is triple the price of Febi or Beck Arnley ($150 vs.
$50)...  Flex disks are $47 per (Febi) from AutohausAZ.

If Andrew is lucky, just a flex disc is at fault, _AND_ he will get it
fixed prior to catastrophic failure.  Flex discs are the weakest link and
require periodic replacement, and as a bonus a bad flex disc can be
determined with a visual inspection.

Yeah, and I wouldn't be driving it much like they, either.  Driveline failures

It's definitely a drive train component that's making noise when 
loaded/unloaded from what you describe.

That would be U joints, flex discs and CV joints as far as I can think of.

If you get the back end off the ground so you can turn the drive shaft and rear 
wheels it should be easy to identify.

Something is wrong with the driveshaft or a half-axle.  If you can make the
noise change by weaving side to side, it is a half-axle.  If that has no
effect on the noise, then either a flex disc, the center carrier bearing,
or a u-joint is probably the cause.

That's my guess. 

"This has been going on for some time"

Nice to wait for something to get to the point of destruction.

[MBZ] Very loud knocking noise in my W123 300TD

[Andrew Strasfogel via Mercedes]

Loudest in first gear under load. It's as if someone is banging underneath
with a hammer.  Tends to diminish and go away as I move up through the
gears.  I crawled underneath and checked for loose exhaust pipe but
everything seemed tight.  The noise appears to come from the rear.  This
has been going on for some time, but got really loud just today.

Any ideas on what might be the issue?
