Hi Crawlers,
I have been doing some reading on Bob is the oil guy, and I'm wondering if I can use a oil in the steering knuckle?
The problem is you would leak the crap everywhere, and leave your stuff dry. The seals are not designed for it. Yes it would be sufficient and possibly better. You have many other considerations, top bearing lube, and a sealing surface. We use this type of lubrication every day, not in this application.
