As I suspected the splines are the same size, however the ASR axles are 30mm from shoulder to circlip base and the non-ASR are only 26mm.
So it would be possible to use the small CVs on the large diameter axles with a 4mm spacer. The wheel side CV appears to be the same between them, which may ultimately be the weakest point.
...
So the outer CV is the same size on both, identical to the M104 inner. Also uses 26mm spline depth.
...
Everything about the V8 Inners are beefier. Bigger bolt diameter, larger ball cage, thicker center star with 30mm spline depth.
Did you use v8 4 bolt flex discs? I need to go back through the thread.They are 18" with 225/45s up front, with the lorinser springs the rubbing was not great even with heavily rolled fenders. The H&Rs are much more reasonable and work nicely. The oil supply fitting is a 16mm to 4AN, straight thread 16mm with a copper washer. The om606 oil feed boss is large and flat perfect for a crush washer.
The super wagon has been running and driving great, just rolled over 1200 miles so the "new car break in" is done. The methanol injection with Snow 50/50 boost juice made a very noticeable increase in power. Will be headed off to the body shop in the very near future for its 036 Widebody transformation, then meatier tires and more boost:?
And thanks very much for the information.Did you use v8 4 bolt flex discs? I need to go back through the thread.
The outer axle shafts apparently fail at the splines with serious tires. I am looking for a usable factory hub with larger splines to have some custom half shafts made with the larger knuckle and splines on both ends.

How serious do the tires have to be to cause the spline failure? Are we talking Pilot street tires on the street, or Hoosier drag radials at the track with VHT?The outer axle shafts apparently fail at the splines with serious tires.

Serious enough to provide any traction before 3rd gear at 60mph. Which practically speaking means Hoosier drag radials, like a 265 rear.How serious do the tires have to be to cause the spline failure? Are we talking Pilot street tires on the street, or Hoosier drag radials at the track with VHT?
Also, does the failure tend to be at initial launch (zero mph), or at speed at the power peak during a shift, etc?

That dude in Norway had one fail in 3rd gear during a pull with street tires.Although I believe they have failed on street cars also.

Where do you buy your sanitary tubing? Regular rolled 300d fenders work fine; mine rubs only on the liner right front on deep compression.Got the vented 036 fender back from the custom metal shop, looking very good
It is going in for the rear 1/4 panels this week then finally off to the bodyshop, who will have their hands full making everything just right with all these trash angel 036 parts![]()
Standard fenders may clear most larger wheels, but they are not widebody, and also have a different shape on the wheel arch. Blair is installing a complete 500E front end, plus 500E rear flared fenders too... complete widebody treatment.Regular rolled 300d fenders work fine; mine rubs only on the liner right front on deep compression.

Oh I see. I recall Russell doing something similar in seattle but I am wondering if doing so would actually solve any problems or is just to win the parking lot wars.Standard fenders may clear most larger wheels, but they are not widebody, and also have a different shape on the wheel arch.

It allows fitting MUCH wider wheels/tires in the rear, and moderately wider up front. And IMO, it looks soooo much better than non-widebody, but as always looks are in the eye of the beer holder...Oh I see.

On a standard 124, pretty much the reasonable limit is an 8.5" wheel on all four corners, with significant fender massaging & spacers required (AMG doc here). Note AMG also specs a travel-limiting strut shaft spacer up front as well to avoid rubbing under compression. Also, AMG specs a 235 tire, and a 245 is probably the max that would work, with a higher numerical offset wheel. At the risk of pissing off a lot of people, I'm going on record that I don't consider stretching a 205-section tire over a 9+ inch wheel as "fitting" on the car.Ok so what size tire do you figure fits the rear on an 036 that wont fit an e420? And are the inner fender liners on the front really that different?
Im not sure the front fender flare on the 036 is any bigger than what rolling a stock fender can produce. Seems like there are some body spacers involved, but those could be added to stock fenders, could they not?
I guess without knowing what the goals are it is hard to say what sort of effort is justified.

Did you swap the radiator support also? Thanks.Electric cutout demonstration, for the prius enthusiasts![]()

I'm guessing he means the lower radiator support, which is totally different on the .036 chassis.I must be missing something, why would I swap the radiator support?

I have never seen a 500e, so it is all a bit mysterious. Above, someone said you were swapping the whole front end, but I'm not sure what that includes, to wit:I must be missing something, why would I swap the radiator support?

Are you the owner or the builder?Quick update; The Wagon goes in to the custom rod shop in the next two weeks for the 500E rear flare widebody addition. I have been utterly buried with health issues & the building of my animal rescue etc et al, and am looking forward to its completion. Updates & dyno runs will be forthcoming (as well as the long-delayed 500E partout), so stay tuned to witness the unmitigated genius of UberKarl. This car can literally tie your stomach in knots (and the diesel plumes can blot out the sun........![]()

I’d throw the Jordinator in there as a pretty good builder too. Though I realize he’s got his own project and isn’t involved with this one.
Baviking1 = Owner and evil overlord, S70/2/UberKarl = builder extraordinaire, GSXR = King Kahuna.
Stay tuned for the fun.....![]()

V8 on left - M104 on right

V8 outer - M104 inner - V8 Inner

So upgrading to the V8 inners may be a moot point if the outers can't take the torque.
Did you actually use these shafts, have them rebuilt, or use new stuff? I bought some with the 500sl diff, but they are over 100k and a bit sticky.
Diff size is determined by the engine. In the 124 chassis, all M119 and M104 have a 210mm diff. All M103 and diesels had the smaller 185mm diff.I guess I didn't know that the gas wagons had the 210mm diff. The diesel had the smaller one.

1993 was the first year of the M104 in wagons, except the 1993 4Matic which was the last year of the M103 in the 124. Check the EPC first. Don't forget to verify the flex disc / flange diameters too.In that case it is possible a rear driveshaft from an m104 car would bolt up. What year did the wagons switch over?
The link in post #95 above has the flange & flex disc comparison info, which should get you started. The EPC would let you figure out which driveshaft part numbers are the same between different models, which may let you figure out what is the same and what is not. But nope, the EPC will not give you any specifications or dimensions.Thanks. I would check epc, but they switched to that Daimler site now and it wont reset my password without me calling them.
How would you look up driveshaft characteristics in epc? I dont think they have that info. Of course it will tell whether a given car has m104 or not.

Yeah. The best flex discs for the car are the thicker 6 bolt 100mm bcd ones from the w210. The hardware is a bit too long for the w124 flanges, but the discs are about 3/16" thicker than stock. Of course this means the stock driveshaft is a bit long, but with the slip joint it will be OK. I found a shaft on LKQ and it will be here in a few days, so I will hope for the best and if no luck then it is time for a custom dual cv shaft.The link in post #95 above has the flange & flex disc comparison info, which should get you started.
