Rear Wheel Seal leak

[Stonewood]

I discovered a puddle of rear diff fluid on my garage floor. It appears my 2018 Sierra 1500 drivers side rear wheel seal is leaking. 

 

Why me. 

 

Truck has 78K on the odometer.

check your axle vent, i did my left seal and a month later it was leaking again. pulled the vent hose off and found that the steel nipple on the axle was plugged

My passenger rear seal starting seeping and I still have my powertrain warranty so I had even less miles when mine started failing. I’m fortunate that it was covered.

I will take a look at the vent nipple and line. I made an appointment to get the truck looked at but it's not until June 8. I'm confident I can do this work myself, but I just don't have the time.

I took the truck in to have the seals replaced. They were both leaking. My wallet is $1200 lighter.

Hummm....sounds pricey for 2 rear seals. Glad I'm a DIYer. Was this at a dealership?

Not to pour salt on the wound, a few years back I had my rear axle seals done for $350. Local shop.

I'm road tripping a 750 mile route this weekend. I have peace of mind.
