Re: Lube leak from front axle

He said I'm looking at $850 for the replacement of the seals. I said I'd keep my eye on it and get back to him.
Question, when checking the level of the oil in the front differential, how do I know it's full? In the old days, one used to just unscrew the nut on the diff, and if a little lub oozed out, it was full. And has anyone one else had a problem with the SMB front axle leaking?
I think you use the finger test if you have a diff fluid drain plug..to see if it's just at the right level from spilling out.
Mine leaks a tiny bit from the front axle seals when it's not level. I saw minor drops on the driveway. My Buddy said it's most likely due to it sitting unleveled for a while which explains the one sided extra fluid pressure load when it's not level.
I keep it level now and the leaks have stopped. It probably needs a new seal but I'm stretching it out till it starts to leak alot or leaks when it's level.
I'm assuming that $850 quote for seals was for both sides?
