Jeep prop shaft.

[DFC1943Fl.Lt.]

Hi all, can someone please tell me what the measurement for a front GPW prop shaft is as the one I have will not fit between the front axle and transfer box. The measurement from centre to centre of the UJ circlips on each end of the shaft is 59.5cm. This is in the fully closed position. will have to try and get a photo uploaded. Not sure what the one I have is off of.

 Looks as though it is longer than the one in your picture Seamus.

Hi Steve 

I’ve measured the one on my gpw in situ, the measurement is taken off the end of the prop in the picture below

Thanks Nick I did think that, its about 20mm to long when I offered it up to the vehicle. 

Next question is has anyone got a spare front prop shaft for sale. 

Cheers Steve.

Thanks Seamus I'll measure the prop tomorrow with regards to your picture.

20mm difference, that’s a bugger, apologies Steve that’s what the Jeep came with, I’ll check my spares to see if I have one.

Hi all again. Looking like I have a post war Cj2 front prop shaft which is 20mm to long. Has anyone out there got a spare one for sale please and how much you would want fir it.

Thanks Steve.

If the long one bolts to the flanges and is in good condition, it might be cheaper to get it shortened than to replace it. There are plenty of companies that can do prop shaft rebuilds out there. I have done a couple myself but had to take great care to get the alignment right as I couldn't balance them. They were fine though.

Yes David had thought about going down that route. I've a couple of companies who I could ask if they feel confident enough to take on the job. I can buy a brand spanking new one but it's £208 + P&P.

Hi all and thanks for all the input info. Managed to get the front shaft from Gavin at jeeparts uk. Think now the rear is to bloody short, would they be a set from a CJ2. Looking to me like there is too much spine showing. Any thoughts would be a help.

[Richard Farrant]

That rear propshaft is definitely wrong, there should never be any splines showing.

Alas looks like you have another CJ Propshaft, their rear props are shorter than an MB/GPW owing to the larger diff housing,.. look in the link below for prop lengths

Bloody just my luck but had a cunning plan. Not sure if it will work but I've taken the yoke off the front cj2 shaft and matched it up with  the rear length of rear shaft. Offered it up and it seems ok, there is play on the slider so fingers crossed. I did notice that the difference between the war time and cj2 front shaft was only the yoke. The actual shaft lengths are the same. So the yoke from the front cj2 shaft takes up the shortfall in the rear shaft. Job done, hopefully. 😬

Make sure the two yokes are exactly in line with each other, else you will have problems.
