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.

 

For once I might have to agree with Derrel on this one.

At the same speeds my '97 E300 runs at a higher RPM than our '99 E300.

And MBUSA has the same rear axle ratio listed.

 

Doesn't matter whether or not you "might" agree.

What any of them have is very easy to verify.

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.

 

Hey Durrelll... Suck Noots!

 

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....

 

Why TF do u even bother Chris?

Its unfortunate its taken such a wrong turn E-Klasse.....

 

C'mon fellas, back to the topic please. Destroy each other on PM's if you will, lol...

 

Chris' PM's already full, LOL!

 

No it isn't....

 

I couldn't respond but sent you an EM......

 

I searched this topic so I could learn more about my Benz. Instead I came across a bunch of school girls bickering. Thanks for no help girls!!!

 

Welcome to Mymb lol. inb4 "post your vin"

 

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.

 

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.

 

Hi every body, i wanted to know differental ratio number for w210 e230 1996 .
