cv joints for914/6 Options

[altitude411]

Can someone school me on axle shafts on a '70/6? Are they the same as the 911? Can I replace the CV's on my car or do I need to buy a complete axle shaft assembly.

914 PET 501-00 #(20) shows 914.332.009.03 drive shaft complete for 914-6. It doesn't break the assembly down to axle and CV joint.

911 PET 501-00 #12 shows 901.332.232.00 drive shaft (PET for for 73 911)
911 PET 501-00 #13 shows 911.332.033.08 drive shaft complete (doesn't specify yr or model)
911 PET 501-00 #- 911.332.032.02 joint (presumably the CV joint?)

That said, pelicanparts lists the CV joint and the complete 914-6 axle as NLA and to me, nothing in the parts references says 914-6 and 911 are same (by part #) although physically, they could be the same I have no experience with that.

GPR parts doesn't list CV's

Automobile Atlanta lists drive shaft complete in their catalog

autohausaz doesn't show much

The 914-6 axles are longer than 911 axles, but have the 911 spline-count. 914-6 CV's are the same diameter as 914-4 with a 911-splined inner race.

If you want to remain stock, a complete axle is a possibility, or you can use 914-4 CV's and an aftermarket, free-floating axle like SwayAway that's the right length and with 914-4 splines... which are the same as the 944 spline-count BTW.

Other's here will chime in with vendors and availability.

Good luck

911 axles are short than 914/6,
911 axles from 1965-1977 are larger in diameter than 914/6.
there is no single replacement CV from a 911 that will work without changing other components.

I don't have a /6, but I do have all the running gear from one. All I did was use /4 axles and cv's. I'm not sure if the axles are different lengths from a 4 to a 6, but I haven't had a problem since I've had the car on the road.

Someone correct me if I'm steering Keith in the wrong direction.

This is exactly what I did a few years ago. I had some old -4 axles
with junk CVs so I got new CVs from one of our members that modifies
the beetle ones. -4 and -6 axles are the same other than spline count.

Put the 914-6 axles/CVs in storage. Once installed no one will know anyway.
Of course you re-use your stub axles.

What are the differences between -4 axle assemblies and -6's? For those doing a conversion from -4 to -6, can you just use the -4 axles (assume a low hp -6 engine)?

[pcar916]

I used the 914-4 axles and CV's for several years with a 2.7L engine. Those axles worked with both the 914-4 and 914-6 stub axles in the trailing-arms.

If/when you convert to 5-lug in the rear, to stick with 914 running gear you'll have to get 914-6 stub axles in the trailing arms. Then both 4 and 6 axles/CV's are fine.

Frankly, it's often no more expensive to go with larger 100mm CV's and 911 output flange/stub-axle by the time you pay for 914-6 stub axles. There are several good links here on that mod. I ran the 914 gear even with my 3.6 until the CV's wore out. Then converted to 944 CV's on modified 914-4 axles.

All of that might be beyond your scope but it's all documented on this site, whichever option you choose.

Thanks to all for your input and information. I'm learning....

Complete axles are available from Porsche for under $300 per side depending on where you shop. They will bolt up to either the 4 or 6 stub axle. They are plug and play and have a Porsche warranty.
