what kind of gear oil does it use etc.??? I keep adjusting my steering box, but it comes out of adjustment withing about 10 miles. the steering is so loose in the front end I think the thing is almost dangerous to drive. I adjusted it in my other k5 right after I bought it, and haven't had a drop of trouble since. I've got a wrecked k5 here, and I'm wondering if there is anything I have to be concerned with as I remove it. I think this would be the easiest way to solve it.
