Bending rear axle for negative camber

[R59]

I could point you at a car that has been very reliable, runs an English axle which is slightly "out of tolerance" (ie: neg/toe-in), and has won a certain championship a number of times, without breaking. And it's got a lot more horsepower & torque than your Cortina.....

You worry too much!!!
If its done properly, all you'll know is that it's ever soooo much better.

I don't know how to explain it fully (or indeed if it will be useful!), but V8Supercar axles have the splines "barrelled" to account for the camber.

I didn't think thay ran solid axles . . .the FOrd Falcon model I bought my son at Bathurst museum isn't!

I can understand the 'barrel' method though, it would allow a modicum of alignment, but must, if done incorrectly, considerably reduce the contact patch of the splines?

I am sure I read somewhere they do have solid axles Zef in the same way as NASCAR does.

Yeah, the do, generally the Road cars are not (there are exceptions, like the Utes)

As I think I said at start of thread, I ran a bent english axle for two seasons without diff or bearing problems. Had about 7mm off true at one end, and 5 at the other, so not a huge difference, but it was toeing out, so handling was badly affected (that's my excuse for crap driving)

alittle offtopic but instead of making a new topic I will ask here

I want to build the mumford linkage, but what do you use for the center pivot? a bushing? roller bearing? or any better idea's?

how big uniballs do I need for the rest? is 10mm big/strong enough? or should I go for 12mm?

Needle roller bearing. We keep trying the normal bearing and contact bearing and the keep breaking. Didn't have a problem with the needle roller type.

what dimension do you use? and how do you mount it? do you use a tube with correct internal diameter and press fit? or?

On which bearing type?

the needle roller bearing for chassis mounts

The needle roller bearing was about 32mm OD, 12mm deep and, with the supplied bush, about 10mm ID.

It was a light push fit and loctited into the bell crank. Then, because the bearing can just slide up and down the bush the whole lot was located with nylon spacers running.
