The 608.9
My Front 60/44 hybrid + some build begins:
Since i got a couple of PM's recommending i post a seperate thread regarding this I guess Im going to start one. there isnt a whole lot to cover and i was posting pictures in my jeep build thread but what the heck. heres my bonified full on polished turd for a front end.
As it comes together i'll post pictures, the same info will be post in my build but this seperates it for those looking for info on a 60/44 hybrid build.
wasnt sure what to call it there is nothing that rolls off the tongue like 609, or 60/44....but its not entirely a 60/44 hybrid its more imho with a jk44 R&P which is a different animal in many regards with the d60 sized pinion shaft, larger ring gear and deeper cut gears it deserves a little more consideration.
So Im going to call it a 608.9 since its a hybrid running a ring gear is 8.9" and its being matched to D60 outer parts
For my application i needed a low pinion front end, im doing a low slung sua build on my old cj and wanted a lp sua housing that would fit that part while looking clean and somewhat deceeiving.
I was eyeballing a 609 but for the money and parts that i already have this seemed like a fun alternative to try and build. My .02 is the RD147 is a little bigger than the RD99 air locker and they both have 35 spline side gears but the pocket bearing forces the RD99 case to be smaller but only marginally so. the dana 44 locker and the pinion offset of the D44 was a little better than the 9" for my passenger side front low pinion application .........the hypoid on the 9" is better for more tooth engagement and stength but the new cut on the jk gears seem to make up for alot of the old school dana 44's short comings in the pinion department.
Anyways a 3rd member drop out front end is so 2000...... if im going to be sticking to my old school build i got have it look the part and a dana 44 housing just looks like 1989 and therefore nothing special and a slightly modern upgrade with a tiny weenie run of the mill D44 girdled cover keeping it togehter and as a mask hiding the beefed up internals. Anyways I already have dana 44 housing so cost wise its a wash until you add the additional cost of a custom 9" housing and a high strength low pinion drop out, pinion supoport/skid.......
So this is the way the parts have fallen together:
So dug I up a J20 Dana 44 front housing (3" tubes with 1/2" walls) and low pinion
(YES I WANTED LOW PINION)
Picked up a new 4.88 JK Dana 44 8.9" ring in pinion (maybe not a ford 9" ring and pinion but close enough and an improvement over a 8.5" lp D44) and install kit. through Carl with Jana enterprises
I picked up a front dana 61 for cheap to steal most my parts from
Welded on the D61 king pin C's
chased down A 35 spline dana 44 ARB 3 series or also called a high speed carrier
Set it up so the short side shaft out of a chevy D60 can always be ordered or used and made the long side shaft the custom unit.
Axle seal for the 3" x 1/2" wall D44 tubes to 35 spline shafts is Napa #15292 its a double lip seal
did a little bit of shaving (grinding) to the bottom of the 44 housing
What i'm expecting this to end up being is Good clearance, lighter weight, stronger than a dana 44, close to a 609 in strength and in a package that is fairly decieving on the outside.
i'll have no doubts about running sticky 37's or 38's on this setup. granted ive picked my tire size and configuration just saying. sure the 609 would have a stronger R&P but the carrier is arguably weaker and a front 60 would have been ideal but would have hung down more and weighed more...... this way my setup keeps the rig a sleeper somewhat.
thats where things are at right now.......... the 608.9 is starting to come together.

I've gotten some PMs regarding this thread Sorry about the pictures webshots closed up and it'll take me awhile to remember what pictures used to be posted where, I'll be updating it as i have time
