70K miles on the TourX.
Recently took it in for an oil change.
The tech showed me a tiny leak from the transfer case output shaft (going to the driveshaft towards the rear diff).
That seal was replaced. Few days later it started to leak again. I was told the seal has failed and was fixed at no cost.
Week goes by and I'm seeing a new leak on the ground.
I go under the car and notice a leak from multiple bolts on both sides of the unit.
I don't know if this is still the transmission or the transfer case.
The prior puddle on the ground smelled as I remember rear differential fluid from my RWD car days.
This fluid now has no smell, and is somewhat red in color.
I did have the transfer case and transmission fluid changed (I want to say last year). I keep all of my receipts and have a binder. The work was done at my local Chevy dealer.
What gives?
