I was looking at the Rear axle ratio and how much they changed from each E-Class model and year.
In 96
Rear axle ratio 2.87:1 (E300 Diesel)
Rear axle ratio 2.87:1 (E320)
In 97
Rear axle ratio 3.46:1 (E300 Diesel)
Rear axle ratio 3.07:1 (E320)
Rear axle ratio 2.82:1 (E420)
In 98
Rear axle ratio 3.46:1 (E300 Diesel)
Rear axle ratio 3.07:1 (E320)
Rear axle ratio 2.82:1 (E430)
In 99
Rear axle ratio 3.46:1 (E300 Diesel)
Rear axle ratio 3.07:1 (E320)
Rear axle ratio 2.82:1 (E430)
Rear axle ratio 2.82:1 (E55)
In 00+
Rear axle ratio 3.07:1 (E320)
Rear axle ratio 2.82:1 (E430)
Rear axle ratio 2.82:1 (E55)
What would account for the differences? There are companies that sell upgrades for example from 2.82 to 3.46 for better off the line performance. Will the rear end from the 98 E300 fit in the E320 and do the same thing?
I already talked to Carl from Bergwerks a while ago. They offer for $1400 to $3000 to do the conversion I just mentioned. You end up with the ratio that the E300 Diesel has at 3.45.
So why doesn't the E55 already have the 3.45? it has the 2.82 rear end. Is it becuase it is already quick enough off the line so the lower rear end ratio gives a better top end? I wasn't asking for where to get this done but if anyone has done it and what results they had. If you have an E320 and thought to improve it buy putting an E55 rear end in it, you would actually going to a lower gear ratio.
This listing is NOT correct at least as far as the ratio listed for the '99 E-300 DT.
Mine has the 3.07 ratio.
I'll go out on a limb and say that the '98s are also delivered here in NA with that same 3.07 ratio. It should be the 2.82s that are standard for the V8s.

All anyone needs to do is to crawl under with a rag in hand and wipe off the grim in the lower right-hand corner of the differential carrier and read the ratio!
They even supply the carrier part number I think? :p
I cannot imagine MBZ installing 3.46s in the later 98/99 E-300s with their tremendous low-speed torque available at only 1600 rpm. With a 3.97 first gear ratio, that gear combination is simply uncalled for. As it is now, I seldom use first speed, unless there is a steep incline.
The second gear ratio of 2.41 times my 3.07s combined with my relatively "loose" T/C is plenty to get it moving rapidly.
I only wish the 2.82s or something higher would fit. Revs at todays highway speeds are needlessly high.

At the same speeds my '97 E300 runs at a higher RPM than our '99 E300.
[ You mean daddies car out here in California, don't you? When the last time he let you drive it? ]
And MBUSA has the same rear axle ratio listed.

Are you upset because your car doesn't have the "beans" to do the job, and needs that combination of 3.97 times 3.46 to get it away from its' own smoke?
You think you know because when you drove daddies car and you could see the differences in the tachometer readings, but are simply too lazy to crawl underneath and check for yourself. At your age, I guess its getting to hard to get out and under?
I've known some young dummies in my time, but you win the prize!
Don't say anything here unless it is constructive. No one here has asked for your stupid comments.
No wonder you have so many posts. There is basically nothing to any of them!

What's the prize?
You hypocrite. You talk about destructive comments, look at all of your posts on every forum your ignorant melon has encountered.
Clearly you do not have any sense of humor. It's sad that such an elderly man like yourself must always be detrimental to the group.
I hope your joints didn't ache too much from the arthritis you must be enduring while you had to take a look under the car at the rear end. No wonder you're bitter....

I just crawled under my 1999 E300TD and the ratio is 3.07, so the table above may not be correct.
Remember, if you change one component to something different other than stock, you have to change everything else. The transmission, rear end and the Transmission Control Module(TCU) all go together, otherwise you will have gear error codes and the car will go into limp mode. Also, you can’t use any components from 2000 and up, the TCU is different. I heard it can be done, but you will also need the shifter and do some rewiring.

Yea I have order circuit boards for this aftermarket TCU/TCM https://github.com/rnd-ash/ultimate_nag52 (https://ultimate-nag52.net/). I figured I would install and see if I can configure for the 3.07 stock differential, if I can get it working, then I will change diff and git it a try.
why dont you forget about all the HS FUYAA----- hook up DAS and you will quickly determine what software is in the TCU and use EPC to determine the rear ratio that the factory installed then start
It was far easier to clean oil off the differential and see that it is 3.07 ratio. I am going install diff from E420 which is ~2.82.
