I have a slow leak at the output shaft on my np231. I was going to just replace the seal, but I've heard that with almost 200k miles, I should also install a speedy sleeve b/c of the wear on my drive shaft. Problem is, the knuckle-heads at auto zone have no clue what I'm talking about, and I refuse to enter a Pep-boys. Where would you find one of these gizmos without having to order it online?
