im getting real pissed off right now. i think ive found something that i cant do. im trying to put my 4.56 gears in a front dana 44.i have the pinion in,,but when i try to put the carrier in,it wont go. even with me trying to turn the pinion,it wont fall in place. it will fit though if i take the pinion out. what am i doing wrong here? the axle is a 74 ford f100 dana 44 ive tried putting in shims,taking out shims,,,everything i can think of,,,,,someone please help!!!!!!

Case spreader is the easiest and correct way. Dead blow hammer will work.

A friend once told me he would freeze the carrier and ring gear before installing. He said it was just enough to make a differance.

but the thing of it is,,,,,the carrier will fit when the pinion is not in the case. the carrier had reverse cut 4.10s on it. it should still work on a standard rotation diff,,,right?

You guys miss read him. He can get it in the case with the pinion out. So, it's not the case needing spreading.

My guess would be you have standard cut gears but you need reverse cut gears or vice-versa.

Heat and cold work wonders.
For many fits like this i place the tight part on the Furnace and the fitted part outside in the cold...
If it's not winter:) I use the frig....

I would say nope. You need the right gears for the right carrier.

Guess I wasn't reading close enough :(

I'm with you .

the guys at drivetrain direct said that the carrier wont matter if its rc or standard rotation. just as its the carrier for the lower gears.

But it doesn't seem to be working ;)

Can you send a pic of that guy? I haven't seen a pic of a guy that can get his head up his own arse. :flipoff2:

RC gears in RC housing.

RC gears in RC housing, yes. DD guy with head up arse... no. Carrier's a carrier and it doesn't give a crap which way the teeth point on the ring and pinion. It's just a high ratio or low ratio thing, maybe you don't understand.
I agree with the few above that read closely before replying. Wrong ring and pinion.

Are you sure that you are putting the carrier in with the ring gear on the correct side of the pinion and not flipped 180 degrees?

Isnt the case break at 4.1:1 in the 44? 4.56 is a different case that is interfering with the pinion?

Tired so I may be forgetting everything.

Get GearMan or River City Diff. a call

Carrier break on a D44 is 3.93. Sounds like that to me, you have the wrong carrier.

It is the wrong carrier the dana ' s all of them break at 3.92 you will never get it in there unless you blanchard grind about .165 of off the back of the ring gear

A 44 carrier is a 44 carrier. The break is at 3.92 and up or 3.54 and down. Sounds like they sent you a rev. cut gear set. Does it look the same, as in, the gear teeth flow in the same direction as the old 4.10's? If you gave them info off the rr 4.10, that may be what happened.

I think this is him....and your right, RC housings use different gears than Standard housings


:usa:

Is there a carrier break on the RC 44's. I know on the RC 60's there is not they just use a thicker ring gear on the lower gears. The RC carrier is the same as the high ratio (3.54 and up) standard carrier.

Your Ford axle, if it's from an F-100 or F-150 will use a REVERSE CUT gear set.

Carrier break is 3.92 and up. You need this carrier for your 4.56's.

I think your gear set is wrong.

ANDY

if everything is correct, ie... gears/carrier/bearings

maybe you have the pinion depth set incorrect.
when the carrier will go in no further, and the ring gears hitting the pinion? are the teeth starting to mesh or just not even close?

maybe you got the wrong inner pinion bearing or race, i've seen the wrong ones come in kits before.

also, are you sure the inner race is seated good
