Hello,

thank you for your answer.

What is strange is how E30ROB is arrived to fit 135 rear with 128 front Propeller shaft if splines are differents ?

So i'm going to find some AT 335i axles that match with my 188 diff type.

For information the width of the 215 diff is 280mm ( ~11" ) between the flanges.

If anyone know the width of the 188 type i am really interested.


Best regards

I will measure mine at lunch and postup the distance for the 188. The drive shafts are another all over the board item they differ only by 1.5 mm and that will met shings up. on my wagon I tried to use a combo of 135 and 128 and found out the diameter difference.

not the half shaft, the drive shaft. the drive shaft is two pieces the 128 and 135 don't match up in diameter where they connect if you were to adapt a 135 pumpkin/rear drive shaft half to a 128 front half.

if you are thinking of the half shafts l/r they are different lengths left to right. they are also different lengths from large pumpkin to small pumpkin diff size.

OK, thank you for these explanations!

I think that P/N 33207580945 /46 are what i need to install my Diff 188 type on the 135i rear axle.

Another question: do anyone know if i will have somme ABS/DSC errors after whole rear axle swap? the Pulse generator DSC sensor are differents between 125i & 135i ; but i think that these sensors are only differents P/N in order to match with the specific shape of the 135i 130i 123d Wheel carriers.

What do you think guys?

Best regards

I did not have any error codes.

so you are changing your hubs correct? the outboard spines of 135 halfshafts are bigger and require 328 or 335 rear hubs. You need 135 rear hubs to get use of the ebarake and the axles that you plan on installing when you put the 135 rear brakes on. You can put the Brakes on with your stock hubs and axles but you will not have an ebarake because the rotor has a large style drum for the shoes.

Thank you for your answer.

"I did not have any error codes."

So you have made this swap? 135i rear brakes on 128i? did you use the 135i wheel carrier and the 135i ABS/DSC sensors too?

To clarify, my main goal is to fit the rear 135i brakes (i ever fit the fronts) on my 6MT 125i equipped with a 3,23 diff (188 pumpkin).

I want to keep eBrake.

I plan to swap the whole rear axle firstly because i bought it, and secondly because i would like to fit the 1M / M3 rear bushings subframe at the same time.

Best regards

If you have what is pictured then all you need are the longer axles from a 328 or an auto (188 335) setup and then put your pumpkin in. If the diff in the picture is a an auto and a 188 case the just swap in your diff and be done. The 188 housing with flanges is approx 10.5 inches.
Yes I have full functioning 135 rear brakes with 328 auto axles and pumpkin( I actually have a 3.73 in from my old auto wagon)

Sorry to insist, but did you use the 135i wheel carrier and the 135i ABS/DSC sensors too???

I am afraid to have an error code due to different ABS/DSC sensors.

"If the diff in the picture is a an auto and a 188 case the just swap in your diff and be done."

Sadly the diff. in photo if from a 6MT so it is a 215 one.
Thank you for the 188 measurement --> 11" (215 case) / 10,5" (188 case) is not a big diff-erence (0,5" ; ~13mm) considering the axles are a little "stretching" maybe that i can make a test and see if it match with my diff?

Are you happy with the 3,73 diff? not too tired on highway?


Thank you for your help!

Thank you for your help!
here is what I used
135 hub/carrier/sensors/brake calipers/rotors/ebrake shoes
128 manual diff 188, later swapped in 328 188 3.73 from auto
328 auto axles
stock 128 driveshaft

things I added as upgrades
M3 arms
M3 subframe bushings
Braided brake lines

I got used to the 3.73 and its great for the track. I don't do much highway on it all but once a year.

What I dont get is why 128 guys just use dans diffsonline and stay away from messing with the rear pumpkin size and output, its about $300 more but you keep the stock driveshaft and don't have to squish axles?

Huh?

Diffsonline pumpkin was a straight swap. Drop old pumpkin, bolt in new pumpkin.

Done.

Correct. grammatical contextual error
I am saying its so much easier with diffs online. Part of the problem is that he also wants to run the 135 rear brakes fully functional with ebrake. there still is no reason to try to install 135 pumpkins in our car.

Like I stated earlier use the 135 carriers/hub brake and 328 auto axles and done with a diffs online setup

I haven't verified it yet, but I think swapping the e-brake is as simple as replacing the brake backing plates and just a few other bits. There are only 4 parts that are different between the 135i e-brake and the 128i e-brake assemblies: The backing plates ("Supporting ring brake shoe"), shoes, adjusting screw, and springs.

unfortunately not just the backing plate. the size of the tab and distance from center for the ebrake shoes is different so you would have to add material to that to get it to work properly

Yep

this might be an option
https://www.ecstuning.com/b-assemble...33416760058kt/

it looks like its for the smaller drum and it says you can use performance brakes. there was a thread on how someone found a zimmerman rotor and welded tabs and did a bunch of crazystuff to get it to work with ebrake.

"Part of the problem is that he also wants to run the 135 rear brakes fully functional with ebrake." Correct

"there still is no reason to try to install 135 pumpkins in our car."

One good reason IMHO is the 4 holes Drive shaft, which is specific to the 125i/128i --> I don't think it exists any 215 diff with a 4 holes out flange that match with that Drive shaft.

...That is why in my original post i asked if it was possible to fit the Rear 135i drive shaft with front 125i one...

answer was NO so the best solution for me is to use the 335i/135i N54 AT Axles

UPDATE:


I had very good luck! have now logged over 900 miles on the diff and had the fluid flushed at 500.

the only additional part for this swap was the 135i rear driveshaft half, which slid right into the 128i front half!

The diff bolted right into the subframe as expected, as well as the axles bolted directly to the diff with no issues and I was able to "compress" them in a few inches.

As far as the driveshaft goes, I ordered a 135i "automatic" driveshaft, separated the halves, and slid the 135i rear half onto the 128i front half with new a CSB and new hardware as well as a new rear driveshaft lock nut.

the driveshaft lined up perfectly, simply R&R and BOOM, a 3.46 Helical Team MFactory 215mm fit right at home.

Very happy i did not listen those who said to stay small case and use the 3.73 as the 3.46 is PLENTY!

CHEERS!

If I spent all the time and money you did to make this work, I guess I’d be “very happy” with it as well, lol. I still think anything less than 3.73 is a waste of time, and rather crazy given all the extra work and expense needed to make the (slightly) longer gearing work.

But I guess different strokes for different folks, and all that. Glad you got it working in the end.

An LSD is soon in-the-works for me

I'm thinking that I'll pick up a 3.73 328i pum'kin (around $100 on ebay), and build that with the LSD (dunno which one yet) so that I don't have to take my car out of service for an extended period of time.

I have done some looking, and gather that the 3'er diff (small housing) will bolt right into my 128i no issues. Also, from what I've read, the 328i diff has a bolted ring gear, which is a good thing for doing a swap with. Is this information correct?

Now, how are the MFactory diffs? They're a good bit less expensive than anything else I've seen, which is nice, and they also have a good warranty, and a seemingly good reputation. Should I go for a 1-,1.5-, or 2-way diff? What are the differences?

My car is a daily-driven car, but it isn't usually driven lightly, and regularly gets out on backroads and gets out on-track a few weekends in the summer. I'd like to be able to get some skidding action in the wet out of it, and some better traction and predictability in the snow (as I said, it gets driven).

I appreciate any information and recommendations you can offer, as I'm really knowledge-biased towards suspension. I have WtLn Sbfrm Bushing Inserts (M Bushings going in soon), M Control Arms, and 15mm SwBr. I'll definitely be installing the M (front pos.) and Powerflex (rear pos.) diff bushings when the diff is finally out, since they've been lying around the house for a few months .

Thanks again!

The car had 0 downtime, the only time spent was on the internet asking questions and buying a driveshaft for an additional $80

In the end I came out with a 215mm full pumpkin so I think I came Out pretty good lol..

1, 1.5 and 2 way is how the diff locks on accel/decel

1 way is lock on accel, no lock on decel
1.5 way is lock on accel, partial lock on decel
2 way is lock as much as possible, really

For a daily, I'd go max a 1.5 way. A 2 way will have you chirping tires getting into parking spots. Not that that's bad but you'd chew threw tires with it

Also look into E93 M3 front/rear sway bar - real cheap and bolts right in
