Well really that is nothing. The REAL information jackpot is http://www.sellc.us/remote and that is where its at. This stuff here is just for people to knaw on.

As far as any holes in the above write up goes, where do you see them? I think maybe your name should be BS Rocker. The only holes here are the ones in your head! LOL

The tag is usually located on the back of the differential cover. If it is missing then its likely the rear end was serviced at one time and not re-insalled.

If the tag is missing you can pull off the the cover and the ratio of the gear will be stamped on the ring gear. Just spin it unitl you see the numbers indicating gear ratio.

Stop the press!

Some folks are saying they have proof that the W126 Mercedes does infact have a limited slip differential. While I myself have never had to tear out the spider gears, some folks have made a compelling argument backed with photos to confirm there is infact supposed to be a Limited Slip Differential in the upper class 560 models.

I may stand corrected that the 560 does offer this limited slip differential standard, however the last two we salvaged did not. Perhaps they had been replaced at one time or another, with open differentials or perhaps it may have been an option, but the fact remains that there is such an animal out there.

From what I can understand, these limited slip differentials (As shown in the photos of the 560 differential) are somewhat easy to spot. If you look at the photos above of the 560 differential, then look at the standard open differential you can see the diffrence in design. The non-limited slip "Open" differential looks, well... Open. While the Limited Slip design looks to have less access to the spider gears.

While we do not have any 560 differentials at this time that can be spared, we have plans to break one down in an effort to validate these claims. 

Yes we have found that the 560 does in-fact have a limited slip differential. Apparently the first two 560's that we had purchased for parts at one time or another must have had their LSD differentials replaced with units from a 420. Apparently these LSD units wear out causing noise when turning, and thus we have been skeptical every since then.

So the moral of the story here is this, "If you purchased your 560 used, make sure someone didn't steal your LSD unit!" LOL.

The situation was made worse when a customer from Tennessee purchased an LSD unit from one of our parts 560's only to get it and find out it was just a standard differential. It was not only embarrassing, but we lost a customer over it. The guy was a nuclear engineer too.  

I am sorry PowerStroker, do you own a Mercedes?

No? Well then I suggest that you shut that hole in your head.

I have never had to pay out of pocket for a single brand new Mercedes-Benz part outside of oil, gas, guides ($15), Gaskets ($40) and filters in the 10 years that I have owned one and I am quite proud of that fact.

I realize that one day I will have to break down and buy some rubber based parts and maybe some other "wear" items, but I'll cross that bridge when I get there.

I should also mention that many of the parts found in a Mercedes-Benz rear differential (It's not an axle you idiot) are more expensive brand new than the vehicle you drive every day.

You should also know that I have been building up a nice core stash of Differentials, Gear Boxes, Transmissions and Engines so that when the time comes I can rebuild them. As it stands Mercedes-Benz is not like the Fords that you are used to owning/repairing, as Mercedes were built to last, not to become Obsolete in 2-3 years like a Ford.

So... Have a nice day!

But how much have you paid over the years to acquire used Mercedes vehicles to harvest for their used parts???

Let's just say my Mercedes have paid ME to drive them thru the years.

Maybe Mercedes does that on purpose to prevent riff-raff like you from driving their vehicles, they have an image to maintain after all.

Nope, it just goes with the territory on an $80,000 automobile. I should also mention that Mercedes still offers replacement parts on vehicles older than 20 years! Yep that's right PowerStoker, unlike Ford and GM, Mercedes Benz actually supports their vehicles past 8 years, unlike a Ford or GM where as they quit offering replacement parts from the manufacture. Shot yourself in the foot again, huh PowerStroker?

You should know that I have been building up a nice core stash of tools and skills to repair things when they break down, so that when the time comes I can actually fix what's broken instead of swapping out entire assemblies.  My method also saves on storage space.

Yes I have been building up a nice stash of tools and skills also PowerStroker. So it seems I have you beat! Tell us all PowerStroker how often the dealer or manufacture actually pays YOU to rebuild an Engine, Transmission or Rear Differential? Or do they usually supply you with a factory remanufactured unit and pay you to install it? Yeah that's what I thought! Tell us all when the last time was that the dealer paid you to rebuild an entire engine, transmission or differential? Answer is... NEVER! 

If what you say is true, there would be no need for you to stockpile their parts.

Well let's face it, if Mercedes parts went bad as often as Ford parts, I wouldn't have a "Stockpile" now would I? You know what manufacturers I can't keep in stock to save my life? Ford's and GM's! Every truck, Mustang or Camaro I have ever cut up sold just about everything in no time. I literally have NOTHING in stock for any of the above mentioned GM and FORD vehicles (thats not already spoken for), and trust that I have cut up just as many if not more of them combined thru the years. What does that tell you? Yeah I know what you will say, something about a strong demand, but would there really be a demand if the original parts stood the test of time? I doubt it.

So... Have a nice day!

So in a nut shell, NO you do not overhaul engines on a regular basis, and NO you do not do transmission work.

I DO overhaul engines, I DO NOT do transmissions, however I plan on a full overhaul on several of my (4) stock-piled transmissions. These are not customer pay, however depending on how mine works out I might offer the service.

I have also replaced my share of carrier and pinion bearings, as well as ring and pinion and differential (most of them LSD) swaps. 

I have never had a Mercedes Benz rear differential go out on me, or start to make noises while turning. The only problems I have had is finding that some punk stole the LSD differential out of my 560 somewhere down the line and replaced it with a standard unit from a 420. Most people coming to me looking for a 560 differential are doing so for the LSD feature.

Back in the day people on BenzWorld.org claimed that ALL V8 W126's had limited slip units, however I found that to be false. While it is true that a 560 Mercedes SHOULD have an LSD unit, there are a great many of them out there that have had their LSD units stolen, and thus anyone thinking that just because they had a 560 meant they had the LSD option could be in for a surprise. 

Mercedes does their LSD units differently than what you would find on a GM or Ford. The clutches are not visable and there is no S clip in the center like most others. If you look at my photos in the first thread, the one that says "560 Diff" is in fact a 560 LSD unit, the other one that is shown without any writing is the standard open diff found in most everything else (300 - 380 and 420). Look close, you will see the difference, but what you wont see are the clutch packs.  

Not true Gerry...

I been holding this back from the guys a BenzWorld.org because they always like to steal my info, but Ill let you in on a little secret.

Do the ASR equipped 560's have LSD Gerry? No they dont. So the myth that all 560's have the LSD rear end is not true.

I have also learned the hard way that while all NON-ASR 560's have a LSD from the FACTORY that does not mean that by the time a 2nd, 3rd, or 4th owner buy them the LSD unit will still be in there. I have purchased a few 560's only to find they have been replaced at some point with 420 rear ends. The LSD rear ends get noisy when they wear out and sometimes places will stuff a 420 unit in there because they cost less.

So the old saying on BenzWorld.org that ALL 560's have an LSD is not true.

I was just wondering ... what the F is PowerStroker doing in this forum, anyway ?

If your Limited Slip is not working anymore it's probably because the friction discs are worn out. The job is complicated and involves the entire differential housing and all to be removed. This includes the axles and the drive-shaft.

From there you have to remove the bearing caps on either side of the differential. Once out you have to disassemble and replace the discs. Assembly is a matter of keeping your existing shims in order, otherwise you will be spending some time re-setting it. It still pays to check the unit with a dial indicator both before and after.

With regards to Mercedes and Fords being whole different animals... It's only a different way of doing the exact same thing. I think you need to crawl under a newer Ford Escape and check out the differential and rear suspension, then come back here and tell me Fords and Mercedes are two different animals. 

Now who's bickering?
