Yesterday I put an Aussie locker in my D30. Everything went smoothly, and having a buddy over made the install go very quickly. So at the very end I put some gasket sealant on the diff cover, bolted 'er up and said, "Ok, let it dry and I'll fill it up tomorrow." My friend was supposed to come over the next day with his Jeep so we could replace his ring and pinion (missing teeth on ring, however the hell that happened).
The following day my friend and I get together over my house after work, I fill the diff and say, "Lets test it out."
We go in my back yard, over the creek through the woods to this one hill that my Jeep always had a hard time climbing with open diffs. I put it in 4WD and think, "This is going to be awesome. Should crawl right up."
To my surprise I couldn't climb up it. My friend gets out, we check the vac lines on the disconnect, etc. ----- Nothing. ----- He watches as I try to climb the hill several more times. Only have traction with one tire.
So we head back to my garage, all the while discussing about what could possibly be wrong.
We jack up the front end again and I spin the driver's side tire. Yup, the driveshaft spins. So what the heck is going on? Why isn't it locking?
At this point my mind is racing. Although sometimes wrenching on your Jeep is fun, re-doing this project isn't what I would consider fun. Plus I'm starting to worry about what is wrong and WHY it's wrong.
And then I had an epiphany. "Wait, let me check the vacuum disconnect a minute."
So I pop off the vac disconnect plate and..... yup..... you guessed it. I put the collar on the shaft, but I didn't put the shift fork on the collar
. Talk about an idiotic moment.
Long story short, Aussie works fantastic now.
But I'm still a simpleton.
