: Which Performance Axle ?
02-07-2007, 04:59 PM
There are a lot of posts concerning the replacement of the stock clutch/flywheel combination with lightweight flywheels and various beefier clutch pressure plates.
Common stuff...and NEEDED in my opinion.
That said, with so much extra torque and grip, I was told by my repair shop that there is a real possibility that I could break the drive axles. This is especially true if the car is ever mated to slicks or DOT legal competition tires for autocross or drag racing.
I autocross and do big track events with this car. I certainly don't want to be halfway through a high speed corner and lose a half shaft.
Has anyone else heard of this? Does anyone have any recommendations for stronger/upgraded drive axles?
Any suggestions are appreciated.

A long time ago i came across uprated ones for the SVT, but I have no idea who made them.
Something like $700 each.
But Ford rate the SVTs shafts up to 200nm torque.

Thanks Man. $700 each is a little steep I imagine I could snap a lot of stock axles before I needed to think about dropping that kind of bank.
Still would be interested if anyone else knows something...

Enjo axle shafts are a pair for like 1500 bucks, but they are supposed to hold around 500 hp or somehting like that.

The stock axles is all you need , Not many if anyone is making more power then I am and im not breaking them
The SVT axles are already a lot larger than the standard models.
I could be wrong, but I don't believe I've heard of anyone breaking an axle, even with FI.
That is, not by overpowering, but maybe by abuse or an accident.
Well, there ya go WeeAsp. [;)]
I wouldn't have responded if I had seen Tom's reply, but I was still typing.

I recall a website that manufacturers performance axles having a slot for the Focus and instead of a product, there was a description saying "when you start breaking them we'll start making them." Apparently the drive axles are the only part Ford overengineered on the Focus.

i have done 1 burnout since i puchased my SVTF back in 08/04. during that one burnout, i screwed something up. when i went to turn right, it felt like it didnt want to turn, and the oh-so familiar halfshaft clunking was there. but with my experience with this issue on other cars, i kept driving. after a couple miles this symptom went away. what else besides halfshafts could have produced this issue?

Thanks guys !!
Based on your feedback, I'll hold off on seelling a small child to afford the axles.
I really appreciate it.
As for the last post. I sounds to me like you had a CV joint bind. Happens sometimes and sometimes you get lucky and they sort themselves out. If it ain't broke....don't fix it. [wrenchin]
As an FYI, I'll be starting another thread about performance driving events for 2007. Specifically, on the East Coast. I work a lot with SVTOA and they put on a decent event.
Thanks again guys!

only 1 burn out since 2004...damn i need more self control!

unfortanetly, my SVTF has not been ragged on very much. a few high speed "how fast does this thing go?" runs and a 60-ft here and there.
but does anyone have an answer to my previous post?

I have abused mine a few times, been on a BIG track, had several highway encounters and other forms of axel abuse and I've never had any problems.

I am inclined to think that it was a CV joint binding up on you. I would check to see if the boots are intact (on both sides). If they are, then you should be good to go.
