Well they agreed to repair it under warranty but the parts are taking a long time to get here. I guess they are being shipped via boat ??
It's supposed to the seals or something like that. I have no noise or anything yet - I've been keeping a close eye on the fluid level. The worst thing is the gear oil smell now since it's sprayed all underneath it now.
When I originally took it in for a look the mechanic came out and talked to me - was told that I had oversized tire on it and that could void the warranty but he couldn't see any way of that effecting the seal section of the rear differential.
I'm going to give a call tomorrow to see what's up.
