Hey guys. I know there is a lot of FAQ and other material on this, I'm looking for another opinion. The Stealership is saying that it looks like there is grease in my front diff, indicating a leaking seal. First, I thought a leaking seal usually went the other way. Does it go both ways?? NTTAWWT! Second, Stealership (no offense CDan) wants $800 shinolas for the job. I'm a kind of guy with NO GARAGE (Utah, I have snow right now) and I always seem to screw up brake jobs. With those facts in mind, is it better to just fork over the cash, or is this something a guy without a garage can get through and up his banana rating? Thanks!
