Re: Kurrent "K" Kar Komitments
The axles may be too long and the limited travel is causing them to bottom out and stress the knuckle.
The way to know would be to jack the arm and watch the travel and limit the movement of the travel to stop prior to the binding of the axle. You may need someone to sit on the front to have full effect of the car cornering.
I looks to me that the left side boots tear. Both the inner & outer boots would not retain the "bellows" shape and were torn. It could be that the boots are expanding at higher speeds. The "trick" racing CVs are vented to release the air pressure as the CVs heat up and expand the air inside the boot. Another trick is to add zip ties to the valley of the CV boot bellows to keep them from expanding too much. If I get a chance I'll take a look to see if there is anything that can nick the boots if/when it expands.
Or the easy button - just get a new (free replacement) CV from O'Reillys before each race as the axle is very easy to install...
