How to fix a Leaking Front Axle Output Shaft Seal for 2008 and newer Chevy and GMC 4X4 trucks.

Don’t Follow the older YouTube videos showing early 2000 trucks. There are 2 key differences, and one key difference that will cause you big problems. The older trucks you could just hammer out the shaft, the new trucks have a retaining clip that must be removed before the axle will come out!

I will show you step by step how to replace the front right or passengers side axle output shaft seal. It took me 5 hours to do in my garage. It required limited tools and best of all saved me over $470 by doing it myself vs taking it to the dealer. The dealer wanted 3.3 hours of labour plus tax and I’m sure shop fees etc. on top of that.

Tools required:
3/8″ and 1/2″ Ratchet
1/2″ swivel joint for sockets / ratchet
1/2″ extensions
22mm and 15mm sockets both shallow and deep
7/8″ Socket if you are taking off your tire
Breaker Bar
Lock ring pliers with 90 degree tips
Chisel
Hammer
Brake Clean
Paper towel

Other nice to have tools:
Impact Wrench
Pry Bars
Trolley Jack
Oil Transfer Tool to fill differential
Ratchet Strap

Parts Required:
Seal – Part number 23196678
75W90 Gear Oil 2 Liters (A little more if you spill like me)
