300zx CV's

[Riceburner]

Hey guys, I have some 300zx CV shafts from a Z31 Californian model. Are these of any use?

Too long for use in a 240z/260z good for a z31 mind.

Thanks Mike

You could shorten the shaft and have the splines lengthened at one end then refit the cv joint then they will work. The z31 turbo and r31 cv shafts with the 4 bolts at the hub end are shorter and do work (however most flip the cv cage to shorten by a little, we made a new custom axle for the short side then use the standard shorter axle on the long side. You do have to strip the axles completely to do this but you want to rebuild the cv anyway they will be 30 years old and all)

When I did my CV swap, I simply flipped the cages and ground down the end of the shafts so there was just enough lip to hold the clip on. 4 years or so later still doing fine. Turbo CV axles were used in my case. The passenger side is slightly tighter than the driver side, but I can still get the axle in and out without disassembling any other part of the suspension, unlike what some people have claimed in the past.

They look like my 280zx R200 shafts. How much? If someone can confirm they are the same.

look the same but very different. Longer and the bolt pattern is the same but on a much large pcd. So will not work.

With the cage flip/grind off end, process on stock units,

These get fitted when car is up on a houst, ie lower control arms are drooped down.

And the shafts "just" fit, ie a tight fit.

As the lower control arm when car sits on ground, or when suspension movement occurs, ie bump,

What happens when the cv shafts " bottom" out?

The wheel hub moves in a slight arc, not straight up and down, and at one point, the shaft needs to shorten.

The shortest distance between the diff and the hub is at full droop. It gets longer at ride height, and at it's widest point is about 3/8" longer than at full droop.
