Thanks we were going to stop in the city of Florence for a 10-100 just b4 the trail and air down spot . Only choice is a speedway gasoline station ,I was going to top up on fuel my wife was going to pickup a winning lottery ticket. But we never made it . Pick one up today . So sad to see a fully built Jeep destroyed . Something weird I noticed looking at the rear tire part of the wheel and the axel out I the desert 50 feet from the Jeep no diff oil on any part of it . So I then looked at the busted axel housing leaning on the ground passenger rear tire intact and noticed that there was no oil leaking out . Like the diff was dry . None on the street either.
Thank God no one was seriously hurt, if the Jeep had been over just a few inches or a foot more the outcome would have been horribly worse. Don't know what the distraction was that caused this crash but it is a reminder keep the distractions to a minimum and concentrate on our beautiful roadways and enjoy the scenery!
On another note Earl brings up an interesting point about the outer wheel bearing on our Dana 44 FF's, the outer bearing has a small hole that leads back into the tube that is responsible for lubricating the outer bearing. Many of us change our differential fluid regularly which is a good thing but it's important to consider the outer bearing when doing the process.
Here is what I do to make sure the fluid gets all the way to the bearing an to make sure the bearing is fully lubricated.
1. Change the oil as you normally would (ie, drain oil, remove cover, use brake clean, make sure to allow for full evaporation if you have a compressor blow out the nooks a crannies well. Now replacing the cover and refill to the fill hole with the differential fluid of your choice depending on your needs.
2. Jack up the drivers side or passenger side as high as you can (steep angle) and let it sit that way for at least 40 minutes. This will allow lube to travel down the tube through that small hole and saturate the outer wheel bearing on that side. Don't forget the jack stands, if you don't have them stay out of harms way in case your jack fails.
3. Now let that side down and do the same to the other side again waiting 40 minutes or so.
4. Remove the jack, let rear sit completely level, remove rear fill plug and top off oil level as needed.
Done, and you can be sure your rear diff outer bearing are fully lubricated!
It takes a bit longer to do it this way but trust me it's worth it. Happy trails!
