Blew up another CV joint..., What to do? Options

[yarin]

So I need some advice on this one:

2 years ago a CV went on me during an autocross, drivers inside (tranny side). The bearing race cracked and well, u know what happens then, no power transmitted means flatbed tow truck home. Replaced all 4 CVs with the kit from PMB performance.

All was well.... fast forward to today, the exact same joint blew. I haven't dissasembled for a post mortem but it isn't pretty. Luckily i flat tow the car to events now so getting home wasn't a problem. The car definitely took a beating today, put about 45 total runs (autox school x 2 drivers) on the car before it let go on Avon Tech RA tires, a few areas of the course induced some slip/grip stress.

Motor is relatively stock, probably putting out about 100-110hp crank. AutoX definitely put exess wear and tear on the part, running semi-sticky tires.

So what should I do, replace with another kit? OEM? Beef it up with 944 or heavy duty CVs? Any of you fellow autoxers have a solution that won't cost me a fortune?

Thanks!

Like HAM I think there is something specific to your car.

I have never broken a CV (yes, I'm knocking wood) and God only knows how many miles are on them. If they were inherently weak I think I would have broken one considering the use I put then to.

I check for slop often by just grabbing the axle and turning back & forth...feeling /listening for movement. There should be at worst a minute amount of slop...none is preferable. To remove them from the splines takes a couple light taps with a punch & hammer.....no slop there. Moly grease, of course.

Not much help here, eh? (IMG:style_emoticons/default/confused24.gif)
