Yesterday while driving to work, I heard a terrible grinding noise in my front axle. I parked it immediately and got out to do some investigating. The driver side hub was cool to the tough. The passenger side was pretty hot. I stepped back and saw the wheel was leaning in quite a bit (positive camber). I didn't want to cause more damage than necessary so I got it towed home. I replaced the bearing four years ago and I noticed the spindle on that side was pretty chewed up but not really bad enough to get a new one. Now that I am going to be rebuilding that side anyway, I will be replacing it. So my question is, are the 1/2 ton and 3/4 ton Dana 44 spindle the same or not? I have a friend that has a brand new spindle for a 3/4 ton and he said I can have it.
That sucks, it could have been a lot worse. Sorry I can,t help you with your ? but is that a yellow lab? cause I have a yellow and they are awesome pets, lives to go swimming on the weekends.
Too much grease, over greased the wheel bearings!!
But it has been running fine for over four years now, when I replaced all the front bearings. I did take it apart just now. The outer bearing's gone. The locking hub is all kind of fudged up, probably from the loose roller bearings eating it. The spindle is also chewed up even more. So my question still remains, is a Dana 44 11/2 ton and 3/4 ton spindle the same? I was hoping NumbersDummy would chime in on this one.
As I understood, the 3/4 ton was a larger spindle and bearing. I think I recall a couple people here adapting them over the 1/2 ton, but you end up with 8 lug in the process.
I pretty much did that. I took my spindle over to my friends house and they are different. Wish I snapped a pic of them side by side, but I didn't. Thanks for all the replies.
That's some scary lean you got going on there! Glad you saw it before the wheel and the truck parted ways on the road.
Even though you've had it apart and back together before, are you familiar with the "by the book" bearing adjustment procedure for these axles?
Can make a big difference doing it right or wrong.
And what lockouts are you running? Stock Dana/Spicer or aftermarket?
If the aftermarket type, make sure you're not leaving that big factory coil spring inside the hub. Not compatible at all.
Good luck. Glad it's going to be good as new again.
Nothing like unplanned work on your truck in this kind of weather!
WOW guys, 4 years? The maintenance schedule spec is repack the wheel bearings every 12000 miles or once a year. Did yo do this?? Over greased is a term from the farming community if something goes out prematurely it is often a question "did you over grease it?" Often implying that it ran dry and failed. I have a 1978 with original bearings and races and spindles. Persumably 300000-400000 miles on those, I repack my front bearings once a year.
