I've forgotten, is your 2.2 an automatic or a manual?

I'm working with a 2.5 turbo in an '87 which has a stock 2.65 diff.

I currently have an entire '84 subframe swapped in with a 3.23 diff and the gearing is pretty much dead on. I also have already adjusted the speedo to the 3.27 diff so there's more incentive to stay at 3.27. The rub is the '84 subframe/axles/diff are not as robust as the '87 with the 2.5dt and the diff fromt he '84 doesn't have the antilock brake sensor.

We initially got the shifter rods swapped around when we did the manual tranny swap such that it was going into 3rd when the shifter indicated 1st so we thought the diff was geared way too high so we swapped over the lower geared subframe on hand. The '84 subframe is now squeaking and in need of some attention so I'd prefer to find the correct 3.27 to work on the original '87 subframe.

Anyway, does anyone know how to verify the 2 differentials are a match except for the gear ratio?

The 2.87 is 1.1 L/185 mm diff.
Only 190 D 2.2 (201.122) and 190 D 2.5 (201.126) have 0.7 L/168 mm diff, but 201.126 with ASD also has 1.1 L/185 mm.

300 E-24/300 TE-24/300 CE (in other markets 300 CE-24, engine M104, 124.031/091/051), 400 E/E 420 (124.034) and 500 E/E 500 (124.036) have 1.3 L/210 mm diff.

I don't know if this has been posted yet but this chart is pretty good.

Here's the info from the potential replacement differential;

The back stamped numbers are 0272858 3.27
The number before the 3.27 is a serial number.

The numbers/ letters on the passenger side are...

TE 88
+GF+M 8
5899A

With a big "40" casted before the ABS sensor.

-The numbers on the driver's side are

GGG-40

With another big "40" following it.

It has a part number casted on the housing but hard to read. I think it is - 124 351 25 01


- Now comparing the 3.27 to the 3.07 ASD diff that I have in my possession, they are clearly the same housing and look to be the same 124 351 25 01 part number on the driver's side.

- yes it does have an ABS hole for it.

my original '87 diff was 3M 86 +GF+M1 5889 (the second 8 could be a 9) with this one being TE 88 +GF+M 8 5899A.

Things look promising but can anyone definitively confirm these differentials as interchangeable?

Thanks!

Here's the axle flange I need to fit the new diff

The important digits is the ratio & the housing p/n only.

The 124 351 25 01 (or 124 350 37 20/124 351 39 03/124 351 25 01) is the p/n for the 1.1 L/185 mm/ABS diff housing.

The diffs with and w/o ASD have identical housings, but have different axle shafts (a.s. for diff with ASD is shorter).

Why do ask this question?

Fifteen years ago, I bought a 1987 190 that was a 5 speed 2.3 gasser that had been converted to a 2.5 diesel by an MB diesel fan who lives in Columbus, Ohio.

That vibration, which I could never completely eliminate, ultimately caused me to sell the car. It was aggravating to me..... With a 3.27 rear axle, my driving habits had me at that rpm range and gear often.

I ask because in our 2.5td converted to a 5-speed manual in 3rd and 4th gears only when under any load with the rpm's between apx 1400 and 1900 there is an annoying noise I'm trying to track down. Below 1400 no noise, above 2000 no noise, 1st, 2nd, and 5th gears never any noise. I have one broken exhaust doughnut on the muffler that I need to replace (temporarily tied up) that I hope might be the culprit. I think the noise originates from behind the tranny but I'm not positive.

Do you recall what steps you took to address your problem before selling the car? What did you think was the source of the noise?

Do you believe then that the potential donor diff of 124 351 25 01will bolt in place of my current R124 351 06 08 if I use the rear cover and axle shafts from the R124 351 06 08?



Thanks again for your input!

If I'm reading this chart correctly Technik des W201 a 2.6 gasser should be a 3.07.

Are you sure yours is a 2.87?

In chart is data for the Euro-models.
The US-ver of 2.6 (201.029) was equipped with 3.27 or 2.85 diff.
The 2.87 diff is from 190 E 2.3 (201.028).

Ciao!

124 351 06 08 with ASD?

Replaced the exhaust system, replaced the diff, replaced the driveshaft and half shafts, added those big vibration dampers at flex discs (which helped marginally), motor mounts, trans mount.

Also. swapped out wheels/tires with another car.

Nothing, other than the vibration dampers, helped in the least.

At the time, I thought the vibration may have been the flywheel (balance issue).

Check the oil level in the gearbox and worn shifter bushings on the middle rod.
