with all the research that speedy and i have done on a one piece driveshaft using regular u-joints. cost around $500.
I am going to stay with the factory set up.(1 )the flex-disc must take up some of the torque from my V8 (2) it if is in great shape it takes up a lot of the vibration. (3) with the amount of runs i have on my car and the driveshaft from the srt6 has not failed i am staying with it. thanks speedy for saving me money. (4) i'm getting too old to keep making changes on my car that cost money,,it runs great the way it is ,, one of these days i will want to sell it, anyone wanta go fast call,,pm or email me. jim

 

Jim, where is your mechanic located?

Also does anyone know if the Mercedes version driveshaft is interchangeable with a NA version. And the part number if known. I assume it has a pinned u-joint also.

 

just finished testing the replaced u-joint, after 5 tries, that is 5 different times we replaced or moved the u joint, we welded it , we pined it, machined it, very hard to center and then secure it , we I don't think any local shop in any city can replace the u joint with out the tool that centers and pins it at the same time., the shaft i was using is now garbage . i do have another idea and it will work but now i have to wait until i get another drive shaft. the limited yoke is smaller (3" bolt circle) the srt (3 1/4 bolt circle)and the limited is thinner (metal thickness) so no they do interchange, and no the mercedes shaft will not interchange the length and the support bearing location ,so far has not been matched up but only checked 7 of them,,all the small size mercedes cars. still working on it. jim

 

Too bad the yoke ears can't be machined to accept a snap ring. There is plenty of room outboard of the u-joint caps to put in a groove.

I am definitely interested in your future findings on compatibility with a Mercedes shaft. Good hunting.

 

I am the mechanic using miamimatt's shop and of course his knowledge and help

 

Cut off and weld new tube yoke and shaft yoke on?

Or take the 2 piece driveshaft out of a newer camaro or other, and cut and weld on the 3 arm props ???


I glad I don't have to worry about that center u joint anymore

 

ROB, do you have a source for the u-joint in this discussion?? With a ujoint, I know that I could change my own. Enjoy Woody

 

Old thread, but I thought someone might use this info:
I just replaced the u-joint on original driveshaft. Is costs $31 and it was used on many MB cars throughout the years.
GMB 220-7284 Universal Joint

 

The hard problem was finding a place that had the mercedes pin tool to install a new u joint

 

first, how did you center the u joint ? and then how did you secure it? this u joint with the center hole is used on older jeeps and is too week for the torque in our cars.

 

Not sure about old Jeeps, but here`s the list of applications from manufacturer:
BMW: 750iL 1997-88
MERCEDES BENZ: 190 SERIES 1996-81
MERCEDES BENZ: 230 SERIES 1984-74
MERCEDES BENZ: 240D 1984-73
MERCEDES BENZ: 260E 1993-86
MERCEDES BENZ: 280 SERIES 1981-68
MERCEDES BENZ: 300 SERIES 1993-86 1986-73
MERCEDES BENZ: 300SEB 1981-68
MERCEDES BENZ: 350SL 1981-68
MERCEDES BENZ: 380 SERIES 1984-82
MERCEDES BENZ: S CLASS 1996-83

I centered it by pressing the caps in at same depth on all ends (2.5mm exactly). I secured it by tack welding 24mm washers. I can take a picture.

 

is this in a srt 6 yes a pic would be nice... I would make 4 spacers 2.55 mm press them in (which) should center the u joint then ping,, or tack weld that way you save the drive shaft for future use

 

This is on a 2004 limited.
The washers I used are 2.5 mm thick and I machined them to be just below 24 mm in diameter (u-joint caps are 24 mm). I will take a picture tonight.

 

 

good job,, thanks for the pic. your washers are the perfect spacers to center the u joint . i see you used one spot weld on one side and two spot welds on the other . did you reblance the shaft. ? if i had seen one weld on each cap i would not have ask that question,,,and that question was ask because of the speed on the track that i do in my car.

 

There are two spot welds, but one spot is just fusing (no filler rod added), and other has a bit of filler rod.

 

So as I under stand the GMB 220-7284 WILL FIT THE 04 COUPE? I have the specs and plan to use them to get one without the center hole......want to be sure this will fit mine prior to getting one and pulling the shaft.
