Can anyone give me the lengths of the shorter M2 shafts please?

 

 

I'm going to get a set made but I need to know what length to get them made.

I measured the m2 shaft for the driver's side at 14 13/16". As for the passenger side, I don't have the m2 shaft. I'm using the stock 300zxt driver's side shaft on the passenger side now, which measure's 15 3/8".

Thanks. I didn't atually realise they were different lengths, I thought it was only the input shafts that were different lengths.

 

 

I guess they are both shorter than the originals by the same length, so if I measure that against my original I should be able to work it out. But hopefully someone can confirm the length for me before then.

 

 

 

 

 

It may be that it works ok on mine with just the cages reversed, but do they work aswell reversed?

This is how it is stock:

I just took apart my stock 300zxt axles yesterday. Driver side 15 3/8". Passenger side 15 13/16". Longer input shaft goes to longer passenger axle. Shorter input shaft goes to shorter driver side axle.

 

Per M2 instructions:

I'm to use M2 axle measured at 14 13/16" with short input shaft on the driver side. Then use 15 3/8" axle with longer input shaft on the passenger side.

 

 

As for reversing the cage, I don't have much to say about that. I've seen people do it and grind down the end of the axle. But that's as far as I've read about it.

If you have the right length axles, reversing the cage doesn't do anything for you. Lengths are correct as I recall. Don't have a set of shafts to measure. Should be in one of the group buy threads.

I'm confused, my stock 300ZXT axles are probably not the correct size, thats why people suggest reversing the cages?  If I had the M2 axles for example then I definitly wouldn't reverse the cages.

 

I'll have a look in the group buy thread.

Stock 300ZX axles are too long. Flipping cages gains you next to nothing. You need shorter axles. I think the Driveshaft Shop is the go to place at this point.

Thanks for confirming that. I'll definitly not flip the cages and will go with shorter axles, I think theres a place in the uk that can make me custom ones as long as I can give them the correct length,

Getting the inner CV off; this can be accomplish in a few manors. Using a pipe, and placing the axle in the pipe, and slamming the CV assembly down into the pipe OR using a dead blow hammer. Using the dead blow hammer, took 4-8 hits to get the inner snap right to give. Mind you I am 145 lbs, so with me holding shaft and hammering, I think this method works great. When taking off the inner CV, be sure to hit the inner portion. Otherwise, the outer cage will shift, and you will never get the snap ring to give.

 

I beat up and destroyed a Pathfinder CV and axle using both of these methods.  Sometimes the inner CV simply will not come off.

 

Rebuilders use a special tool for this chore.  It is a heavy punch that is angled away from the shaft and has a foot designed to fit around both the inner and out race.  The design guarantees that the force of each hammer blow is delivered precisely to the inner race.   They work well, store easily in the tool box, and are, relatively speaking,  affordable,    I purchased mine from Rockford Driveline in Rockford, Illinois for a little over $50.00 shipped to me. Here's their website: http://rockforddriveline.com

 

This is called a cv inner race driver.  They have a number of heavy duty components.  Well worth looking at their catalogue.

 

Obligatory disclamer:  I have no relationship with this folks, other than dropping $ on them for their driver.

Life is a matter of simple logic:

If "some" is good; then it follows that "more" is better; and "too much" is just about right.

I just took off the outer CV assembly but the cage retaining clip got bent in the process. Its the clip thats just inside the lip of the outer housing. Does anyone know where I can find a possible replacement. I looked on courtesy nissan, but it's hard to tell in the parts image if they are talking about the clip I need or the spring clip that is on the axle shaft itself. If anyone has any information it would be really appreciated.

Sounds good, too late for me, but if I ever need a replacement setup I know where to go.

They are black zinc coated to prevent rusting and are made by the same shop that makes the stub axles and companion flanges.  The are $ 350.00 shipped in the US. 

 

Thanks  Joe

I have these shafts that were purchased a few years ago. On Sunday I broke the drivers side (RHD) inner shaft as I tried to start a burnout. I'm have broken 280zxt shafts before and had hoped these would be stronger. To clarify which one, it's the new one I was sent when other had reported breakages. Looks like I'll be putting the original unused one back on.

I am now considering an upgrade to those and looking for recommendations.

The strongest set up you can get with the stock longnose R200 is Chequered Flag's 930 deal. Chromoly stubs for the diff, chromoly companion flanges, 930 CVs with chromoly races, and chromoly shafts. The limiting factor with that setup is the 1.25" diameter of the stub axle.

That's what I've been looking at Jon and my friend has just fitted. I have those outer stubs so only need the axle kit with inner stub and companion flanges. Will those axles be stronger than the one I snapped though?
