broken uni (universal joint) / CV conversion

name this sound "Bang, thud, thud, thud, thud, thud"

No its not a head board on a Saturday night.....Although that would have been much more pleasant

Yes, you guessed it......A broken uni. Just took the car down to supercheap for some globes. Not driving too radically and bang etc etc. I think the damage must have actually occured last weekend during the motorkhana. Here is a photo of the damage:

So, upgrading to CVs?

I got a set of Wolf Creek Racing CVs that I have yet to install in my car if you wanted to have a look at the quality/construction.

No you cannot have mine  but if you wanted to see what they were like your more then willing to drop around and have a look.

After all I am only 15/20mins down the road.

Sounds exactly the same as when my right rear stub axle sheared off leaving the half shaft flopping around, scary sound and you must be happy it wasn't while you were doing 100kph!  Did it do much damage? I was able to sop straight away so nothing else got wrecked.

I had mine explode, I mean literally explode, at the drags. Twice. In two trips....

Both times they lodged in the suspension and bound up, so to find the positives of a bad situation at least it didn't lock up as you were driving along!

I second the wolf creek cv's, but make sure you put nyloc nuts on the outside of them and lockwire EVERYTHING as they come loose all the time otherwise. Here is what I've done to keep mine tight:

I just swapped some stock Z31 CV axles into my 240 recently, just to prevent me from ever needing to make a thread like this. LOL

So far, they are ok, I haven't been to the track, though I have beat on them a bit, so far no problems.

I never broek a stock axle, but I have seen enough of these threads and have yet to see anyone break a Z31 CV axle at the power levels I'll be at while using them.

Hey Whittie looks like you pumped a fair bit of heat into housing to get the old pin out, looks good i did the same works well

Cheers Dazzed, I absolutely love the new arms, everything is just super tight now, no play, knocks, bangs or movement anywhere in the rear end now. Makes a nice solid 'wheels loosing traction' noise when dropping the clutch instead of a 'about to leave the rear-end behind' noise

I'm not sure what they did exactly to get the pin out but it does look that way. I know it was REALLY stuck and took quite a bit of force. I think they may have sanded/tidied up a bit after pushing the pin out so that would have taken a bit of paint off too. It's a pretty solid bit of metal so I'm not worried about it.

I'll be powder coating it all soon so it stays as it is for now.

Hi Galderdi,

The CV's mount to the original zed stub axles on the diff end so you would need to either get stub axles with the same bolt pattern or still buy the custom axles you talk about.

If you want a cheaper option than a CV converion try Hardie Spicer heavy duty uni joints.  The previous owner of my car busted a couple of standard unis when the car was making around 170rwkw.  It's now making 265rwkw and has 9" semi slicks and I haven't busted one of the Hardie Spicer ones.  I do check them before every race meeting though.

Great work guys.  Can someone please change the thread name to something like 'CV conversaions' or similar so that it will come up in a search when I'm ready to look at it?
