I gotta be am nuts…

Let’s try to cut a long story short. The guy who sold me the new axle was wrong. It’s not for a 3.2 ton model but for a 2.8 which means smaller brakes (the body of the axle is the same). I was wrong as well. I forgot about the abs system of the van because it’s very rare on these models. So I had two good reasons to put the breaks from the old axle on the new one. Since somebody on the internet stated that the drive shafts are the same I thought I could use the old shafts with an ABS measurement ring in the new axle. This guy was wrong as well, the shafts are not the same.


The shafts from the right side are not really the same, the ones on the left side are totally different (no photo)

So I’m sitting on the floor of the workshop being sad. Let’s put all together just the way it was, return the axle to the seller and cut my losses in time and effort. Before I was getting really sad I returned home since it usually doesn’t look that bad at the next day.


That’s what I left

The next day: Alright.I can’t switch the shafts. So the new shafts need ABS rings. There are only two problems. First the Axle has no seat for an ABS ring and second according to the Mercedes Electronic Parts Catalogue (EPC) the ABS Ring is not available as a part. The guy at the dealership said the same (hence using the same tool probably).


This picture shows the absence of an seat for an ABS ring. So there is nothing to be seen here. Yet…

So I decided I won’t try to remove the rings if I can’t get replacements. It’s common knowledge that the axles of the mercedes g-model (decent 4×4) are more or less the same as the ones in my van (merc T1). So I searched ebay for an ad with a picture of an driveshaft which resembles mine and is equipped with an ABS ring. Bingo! The G-(Sub)Model W463.225 has the same driveshafts by the looks of it. For this model the EPC lists an ABS ring which looks like mine and has the same inner diameter. What coincidence! Part Number A4633570051, 3 pieces of total stock in whole Germany, next day delivery, 120€ + tax. Alright. Expensive. But a risk I’m willing to take…


The driveshafts fits on the lathe…


…but it’s a close call…

The save way to remove a ring like this is to apply pressure evenly. Heating is dangerous and difficult because you don’t want to overhead the ring and the shaft is pulling out the heat fast. A rear brake disc/drum combination from the junkpile makes the perfect piece for applying pressure. (After some machining). By the looks I’d guess it’s from a W124 or W201 Merc.

It just fits perfectly…


Apply some pressure, give it some gentle beating with a hammer until the ring slips, apply some pressure, beating, … until it falls off
