Ive been pondering the idea of making a HP9" front axle. I have set of complete axles from a 78 ronco. I havent done any measurements yet but have been wondering if it is even plausible. I was thinking of extracting the axle tubes, c's, knuckles, and hubs from the d44 and mounting them on the 9" pumpkin and centersection. The only issue I could foresee is the axleshafts would have to be custom made. And also buying the hp center section. Lemme kno what you think.

 

sounds like you got it pretty much figured out....

what are/would you put this in? maybe a small crawler or somthing...b/c if your gonna spend that much money you might as well buy a d60....right?

 

thanks for the response.
the reason i would go this route is to save money since i have the parts. a d60 to mount in a 79 150 would be very costly. but considering the cost of hi9, it would make it a toss up. but the truck is already front heavy, and putting a d60 in it would be adding more lbs. the 9" is alot stronger than the stock d44 and almost as strong a d60. I could keep it low pinion to save costs, though. I have the parts laying around for the last 5 yrs and was looking for another project as i did my rear disc conversion to the rear 9" last week. I was curious if i can re-spline the d44 axles to 31 spline to fit the 9" carrier or modify the spider gears to accomodate the the d44 axles. but im thinkin of a custom made set.

 

sounds like a very cool project....somthing id like to do anyways....

currie high 9=$$$$ plus custom axleshafts=$$$ which would be more than putting a d60 in it...

ive never heard of re-splining a shaft from 30 to 31 spline......

for you to put that much money in it....especially in a full size, a 9" might not be strong enough depending on the tires...

it would be a perfect buggy axle though....

 

yea, i just thought of it....the carrier for the 9" is 28 spline. but perhaps it can be cut/splined down...if i was going to do it, id get a set of reversed cut gears and keep it hi pinion, just for strength. I think it would hold up better than the d44 i have in there. although im not runnin it with 38 boggers anymore and use it on the street more than anything(except racin quads in the sandpits.). I think the ony diff with a hi9 center and regular is a oil slinger/passage thing. the ring gear may not be able to bring enough oil to the spiders/pinion bearings w/o it.

yea i already checked them out to see how much the gears will cost me. I would have to contact them to see if they sell the slinger seperate. Im sure they could build a whole axle for me, but i would like to take a swing at it. I just dont have the 3g's++ to throw at my truck and i were to spend that much, i might as well spend the extra 2g's for the dynatrac d60. *Im not cheap, just resourceful.*
and i do see where they state that can take 400 horses and 37" tires. i run slightly smaller tires and my engine puts out 365 hp and 485 ft/lbs stock.
