Bravada rear axle problems

I noticed a humming in the Bravada the other day, it sounded like a low tire, NOT! I was on the way to another town, about 12 mile out, the rear axle went out on me. The axle cover seal went bad and let all the axle grease leak out, so now I need to replace the whole axle......$350 for used, or $500 for a rebuilt unit. either way, I will need to be working before I can replace it.
I really like this old Bravada, even with 145,000 miles on it, I enjoy driving it during the winter. I'll keep you updates when I replace it! For now, it must set.
Have a great one all!
