D60 VS 10.25

[NapaBavarian]

I'm considering finding a 10.25 to rebuild for my rear end, from the looks of it they are beefier than the D60, is this acurate? Any important differences?

Unless someone conducted a swap, or your dualie setup isn't factory, I would imagine you have a Dana 70. Actually, it's an early '85, right? ...late '85's have the 10.25" already.

If it's a Dana 70, the ring gear is 10.5" (instead of 10.25" on the Ford)...which IMHO means it's stronger. I don't recall anyone having problems with a Dana 70; OTOH, I don't think anyone has had problems with the 10.25" either (except D_C's parking brake issues ). Also, the 10.25" is easier to service (don't have to pull the axleshafts to do the rear brakes).

IMHO, unless you really do have a Dana 60 or you really want the easier-to-service brakes, I would stick with what you have...

Just my $.02

I don't plan to rebuild what I have since that means pulling it out and not having a drivable truck, I also plan to change my final drive ratio and want to keep the 4.10 axle in case I need it for some reason in the future, an axle at pick'n'pull is less than $100

My initial comparison D70 vs 10.25 was similar to yours, I didn't realize untill now that the D60 and D70 look almost identical, however the pinion diameter of the D70 is 1.750" and the Ford 10.25 is 1.940", I believe this is the shaft diameter, not the diameter of the geared, so I'd like to compare that as well to see what axle has the larger contact patch. GOt that info from the "motive gear" page in summit racing.

dont waste your time with a 10.25 rear.if your gonna swap rears either get a dana 60 or 70.but if your truck is a true dually make sure you measure you rear and the rear you want to buy.measure from backing plate to backing plate at the same spots.and measure spring perch to spring perch on the same spots.a rear end out of a single wheel truck or a cab/chassis dual wheel truck will not fit a true dually truck,they are too short

Um, any particular reason?

Um, any particular reason?

axle seals tend to melt out from guys with a heavy braking foot.(most f350 towtruck drivers)
imho...the 10.25 is right in the middle of the d60 and d70. stronger than the d60 but not as strong as the d70. the contours in the pics are similiar but that's where it ends. the d70 is physically bigger than the d60. there's no mistake over it when seen in reality. the d60 is good for the front side but too light for the rear.

One plus for the D60 is internal parts are alot cheaper than for the 10.25, but I personally prefer the 10.25, if for no other reason, just because I can easily remove the drums to inspect the shoes. I don't have any experience with the D70.

Why not just do it right and throw a Dana 80 underneath it. Is there a way to get a an 80 to fit underneath a ford? Thats what the 450s have right? I know dodges use the 80. That way you know you have a good strong rear.

I think an 80 is overkill for a less than 10,000 GVRW truck. If you want to put one under there though, I don't see any reason why you couldn't. There may be some fab work needed if the purches don't line up.

here we go again.it can be done but you need the f450s tranny/parking brake,and if its a 4WD truck you cant use the ebrake and keep the 4WD at the same time,its gotta be one or the other.the aftermarket brake locks(mico lok)are not legal to use as a parking brake and will fail inspection.plus the rear axle from the f450 is also narrower than a pickups axle includeing a true DRW truck

 

[NapaBavarian]

I took another peek from the back and it does look large, funnt, when looking from the front it looks puney, still looks smaller on the outside than the 10.25 so I'm off to find a van axle :draw :Sly

 

[94f450sd]

carefull on the van axle.i put one from an e350 mini bus in my 95.i had to cut the spring perches off and move themin about 2"

 

[94n/a7.34x4]

i don't know much about the d60 or d70, but i have a 10.25" in my 94 4x4 and i've towed more than i should have with no problems. it also has 200'000 miles on it and it's never been replaced.

 

[Ironman03R]

Why are the chassis cab dual rears narower than the pickup dual rears? I would think that a wider rear stance on a box truck would be more stable.

 

[93turbo_animal]

Ironman with no truck bed to get in the way they could make the axle narrower not as much distance to span makes it stronger and I was thinking the frame itself is narrower from making it straighter for easier mounting of flat beds and boxes
