I've been having problems with my axle seals leaking due to high lateral loads during autocross runs. I've been looking for a solution and found this company that makes seals that sit inside the axle tube to keep fluid from running to the end. They say that many oval track guys use them, but wondered if anybody has used them in a street car application. I run 20 - 25 autocross events a year and 3k - 5k street miles. Has anybody used them? Does it starve the outer bearing causing failure? http://sealsit.com/product-category/axle-seals/ edit: I called them and they told me I have to run a sealed bearing at the axle end in order to use these. Has anybody sourced sealed cylindrical roller bearings for a 8.5" 10-bolt?
