Rear axle I.D. - Pirate4x4.Com : 4x4 and Off-Road Forum

Were there any other rearends, besides the 9.25, that have the 5x4.5 bolt pattern? I need one to match the 44 front i have since the 9.25 is limited to 4.56

Thanks for any help

5 on 4.5 on a 44? its not full time is it? if so run now. the wheelbearing set-up is weak and the bearings go out often when used hard. you'd be better off finding ford d44 stuff from (and including) the knuckles out (5 on 5.5") and just use a ford 9 rear from a truck ( 5 on 5.5"- look for 31 spline axles). hope that helps.

All 2wd before the 94 models had 5X4 1/2 pattern but you will probably need an 8 3/4 from a 74 or older.. not sure what ratio you need but I think you can get 4.56 for the 8 3/4.. you might call one of the gear dealers an see if they go lower..

Speaking 1/2 tons only, the 4.5" pattern was used on all Dodge trucks (2wd and 4wd) during the full-time 4wd era ('74-'79), they all used either the 8 3/8" or 9 1/4" rear. All pre-'74 (8 3/4" rear) and '80-'02 (9 1/4" and 8 3/8" rear) use a 5.5" pattern, including 2wds.

Better do more research newbie

.. I have an 85 2wd that I used for parts for my 86 4X4 it has the small pattern and I had a 74 2wd that I drove many miles before selling it to my brotherwho still has it that has the small pattern..

so go back to your Toys and let the real Moparmen answer this one..

I don't know when they started the 4 1/2" in the 2 wheel drives but all the 2wd 1/2 ton dodge pickups I have looked at from the 60s and 70s were 4 1/2" pattern. I had an 85 2wd that had the 5 1/2" pattern, I think they did a running change during the 85 MY to the 5 1/2"BC in the 2wd trucks. I have a couple 83 2wd parts trucks and they are 4 1/2" BC

Ok, you've played with a truck that had a 4.5" pattern, good for you. I've worked on many more 2wd "toys" than that that had a 5.5" pattern. Its nice that you know everything, good for you, you're such a "real" moparman. LMAO!

the Chrysler 8 3/4" rear end will go lower.. the 489 casting will go down to 5.38:1, and the 742 casting will go down to 5.57:1. I am guessing you want something in that range. As for 5 on 4.5, I have seen SOME early 75 dodge trucks with a 8 3/4", but I think you would be much better off looking for a 74 and older 2wd dodge rear end.

Hope I helped ya out. Garrett
