chipped gears

[KGsK5]

i want to rebuild my d44 and 14b before i swap them under my truck. havent had much thime but i did pull the diff cover... this is what i found. would it be ok swap in axle with the ring with those chips? the 2 in the pic are the only ones.

also, how can i find out what gears are in these?

I would'nt run it ,they look like some rather large chips.They would probably end up getting worse.Count the ring gear teeth then the pinion teeth and divide that'll be your ratio.45-11 should be 4.10

no way are you gonna be able to use those gears and expect them to last at all, I would be surprised if you would be able to back out of the driveway. Time for a new ring and pinion, hope you needed a new gear ratio.

4.09's, pretty bad teeth though. Run 'em till they blow, then replace them.

4.09's, pretty bad teeth though. Run 'em till they blow, and kill your carrier and housing, then wish you'd replaced them when they were all that was wrong.

fixed it for ya. anything worth doing is worth doing right.

I agree. And 44's aren't worth doing, and aren't worth doing right. All he needs is an excuse to get a 60. Even if he keeps the 44, carriers are a dime a dozen if you're resourceful, and I don't see the housings getting taken out by the gears that often. One things for sure, his current gears aren't trustworthy.

If you are going to beat on the truck at all, those gears are not going to last.

I assume from your post that the axles are not in the truck yet. If that is the case, it is easier to go through an axle with them off of the truck.

its still not on the truck... they are rather rusted so im going to pull them all apart and sandblast the entire outside. then replace brakes and now i guess the gearing. what do you guys think about 4.56 gears with a 6.2/700r?

 

[muddybuddy]

depends on tire size. what size are lookin to run? id say youd need at least 35/36s for 456

 

[pvfjr]

Well in a dana 44, 4.56's make the pinion pretty dang small. I think that'd just be asking for it in a full size.

6.2L diesel + Th 700r4:

4.10 gears with 33" tires
4.56 gears with 37" tires

Remember the sweet spot for the 6.2 is 1800 to 2200 rpms.

Use THIS to check any combos.

 

[KGsK5]

thanks for the help guys. and i am going for 36" tires... after i get my 6" lift. oh and i would LOVe a 60... but i can barely afford the lift and tires... the 44 came wiht the truck so imma go ahead and just swap it in.

 

[muddybuddy]

ive got 5.13s and im swappin in the 6.2 with overdrive and 39.5's (38.5" true) i think my rpms are gona be a lil high, but thats a good excuse for 42's

in your case id go with 4.56 so that if you want to go bigger later you can

the gears in my front 10 bolt looked like that, but instead was every tooth. it lasted almost 4 months from the time i noticed it. i was just rutienly changing the fluid. as far as i could tell it has been like that ever since i put the axles in, which was may/june 05. who knows how long it was like that before i bought them. thats not the part that actually completely killed them either, it was the pinion bearings that were destroyed by an unballanced/not perfectly straight driveshaft that ended up chewing the gears completely up.

my point is that they will last alot longer that you would think. i figured i would break them on the trip i was going on the day after i noticed it.

that said, if the axle is out, i would replace them before using it.

Exactly what I was thinking! I've got 2 teeth in my front D60 that look just like that and I'm beating the piss out of them. But keep in mind this is a trail only vehicle that never sees pavement.

highjack: What do you think would cause that? My pinion gear looks good and it's only 2 teeth that are one tooth apart.

im not in any big hurry to throw these axles in... gotta wait for the money for more lift and new 8 lug rims and 36" tires... so while i got em on the ground im gunna go ahead and put in new 4.56 gears. ill just keep beatin the piss outa those 10 bolts
