Dealer Says: Leaking Front Axle Seals

[mwrbunny]

Took my H2 in for 90,000 service this morning. (local dealer doesn't sell new Hummers anymore, but they still service them.) Service rep called me and said Front Axle Seals we leaking (just wet around backing plates at wheel-end of axle...no major dripping) My mind went numb when he wanted close to $900 to fix.

Is this guy single-handedly trying to turn his dealership profits around?

I'm wondering how common this problem is, or if I'm just getting "up-sold" by rep.
