I am running a stock front shaft on my minivan and even at 3 degrees of caster it is noisy, i have heard alot of guys running 5 plus with stock shafts and no problems. at 0 degrees it is quite but im back to flighty steering so i think its time to upgrade the front shaft then eventually the rear....

Any one have good luck with any certain maker

I just heard of a place called cornay.com were they make custom shafts, anyone have any luck with them...

 

Take a look at Tom Woods, iv used them more than once and even under extreme conditions they were the best.
