Hey guys, first post but I've been reading and picking stuff up for a long time. This truly is the best resource for info on my Blazer I have found. Anyway, i'm young, 17, and my first vehicle ever was my '87 K5 Blazer. I love the thing and i wouldn't trade it for the world. The motor's weak and the rockers are a bit rusty but I love it! It has a TBI 305 which is super weak but that's soon being replaced... For now it has a 3" lift and 35's, which rub like nuts....that's gonna get fixed too. Anyway, my problem: My truck has automatic hubs, the drivers side is leaking all kinds of grease, i don't know what this means, but i'm sure you guys will tell me.
