more about the dana44 axle bearing mystery....

ok....4wd hardware swears up n down that the axle bearings they r sending me r for my dana(reference the bill of materials), so that part of my issue should turn out ok

anyways, after replacing all the bearings on the carrier and pinion, i figured id install those into the pumpkin while i wait for axle bearings......

install went ok, pattern look acceptable on the gears, and i understand it may be a bit hard to turn with little lubrication, but it seems to spin fairly freely about 1/2 a rev and the other half rev requires about twice as much effort

i havent put the dail indicator on it yet (i need to "borrow" one from work...lol) but i cant really "feel" any backlash....

the meat of the question is how easy shold the assembly turn by hand when spinning the yoke?

and...yes...i realise i should have done a full rebuild but murphy (read that "the State of New Hampshire inspection regs) mandated the axle seals be replaced now and as many Jeep owners know....Just Empty Every Pocket........ [img]images/graemlins/wink.gif[/img]

It shouldn't be binding up, that's for sure. You really need to check the backlash.

Re: more about the dana44 axle bearing mystery....

thanks for the diagram leve....its actually pretty darned close to that pic, spoke to another mechanic here at work, he says when tightening pinion i should gently spin the wheels as i torque it down, so i guess ill wait for the axle bearings and redo it again....

ill post how it goes...bearings should get here in the next couple days

thanks for the advice all......

Re: more about the dana44 axle bearing mystery....

It bothers me that there is a difference half way around. You didn't say whether it was a half turn of the pinion gear or a half turn of the ring gear, so I can't suggest what to look for. I fear that it won't last long if you run it that way.

Re: more about the dana44 axle bearing mystery....

yes, thats what really concerns me, hopefully when i put the axles in (after relieving any stress in the carrier) and carefully tourque things up it will turn out that the bearings needed a little more tlc on the install.....


so i continue my vigil for the UPS guy!

btw it seemed to be about half of the ring gear....

Re: more about the dana44 axle bearing mystery....

i rebuilt a D35 for a friend that had a similar problem.

backlash was OK half-way around...then it would tighten up so it took about twice the effort.

i checked the pattern and the pattern seemed to change too. i attributed to used (and abused) gears. i filled it up with lube while on the axle stand and it immediately started dripping about 1 drip every minute.

so, i thought i had the seal in crooked. i then started looking more closely at it and realized the pinion was bent. i then threw a dial-indicator on the sealing surface of the yoke and found it did have some excessive runout. then, i pulled the pinion back out, put it on a surface plate with some v-blocks and a dial-indicator and found it was bent about 0.020" in the center causing my problems. i decided it wasn't worth messing with and we bought some new gears.

If you had the ring gear off the carrier you might have gotten a burr or small piece of debris under it.

Re: more about the dana44 axle bearing mystery....

I have seen this happen, but it's always been due to little/no lubrication, as soon as I filled it and worked everything around, it was fine.

Did you find out what it was?
