Custom Length CV shafts.....

Matt · Post by **Matt** » Fri Oct 27, 2006 2:15 pm

Does anyone know where you get some? And a ball park figure? I want them about 20mm longer then Standard MY/Brumby.

Cheers

All I know is that custom driveshafts are VERY expensive. It's probably a better prospect hunting down one from a different car which has the extra length and the correct splines etc. I beleive L series ones are longer than MY...perhaps that is a solution?

talk to bratgeebah.he has a supplier who can match subie stuff up.

L series ons are approx. 50mm longer, so way to long. I went to our local CV specailist here in tvl but had no luck matching splines and lengths

So put L series control arms on as well.
And hubs,
and brakes.
Voila -fixed.

If the L ones are too long, what's the difficulty i getting them shortened? Easier than trying to lengthen.

Good call wagonist, i have found a temporary fix, in the mean time. I have put a 5 mm wider bearing in the front inner, thus psuhing the CV 5 mm more into the inner cup (CV).
BRUMBERTY i like it but, engineering tht i thought was a problem, plus i think is something in the car so io would need, longer then L series ones. But i will look into it...
Thanks for the advice everyone.

Are we allowed to ask why you want longer ones? Top Secret project?

Yeah top secret project!! No seriously my passengers side is to short and is popping out. I think it mainly caused by the camber kit. However if i can find one, i might push out the camber some more....

I only recently went down this path to see the possibilities of making my own shafts. The steel isn't too expensive, the heat treatment is only $50, but getting the splines cut is the worst bit. I'm a fitter and turner and with the equipment I have, it would take hours to do. If you paid a shop to do the lot, your looking at $400~$500 for the shafts alone. Unless you can find someone already set up for spline cutting, but even Driveline Services said they would be that much if they did them.

But how would you go cutting and welding a "L" series one making it shorter? Would you get enough penetration into it, to make it strong enough? Another idea i was going to look at...

Does anyone know if they would last if i was to cut down some L series ones and get a pro to weld and heat treat them?

there is some guy in the states who has cut and welded driveshafts .They have a sleeve fitted over the top of the join.He reckons they're pretty strong as thats what he has used in a offroad racing buggy.

I am a welder as well. I know what happens if you do a backyard job on high carbon steel. Before you cut and shut a drive shaft, think of the possibilities when that shaft comes apart at 100Kph. I am not saying it cant be done, far from it. But unless you follow strict pre-heat and post heat the weld will crack.
To build up some L shafts would be more costly than making them from scratch. If you can find someone to spline cut, I can supply you blank shafts. But my turn around time is crap.

Sorry Cameron, i wasn't talking backyard welding, i was taking professional welding, doing all the right hardening/heating technique. I total agree with your point of worse case i wouldn't play around in that area the consequence could be fatal.....
the_postie you don't have a contact number/website/email for him by any chance?
