A Crazy Idea


Recommended Posts

So I was thinking a lot about axles for some reason lol, and I had this weird idea! What if you we're to take for say a rear Ford 8.8 and get tubes made for it to fit as a front axle and had C's at the ends and a custom setup! So basically turning a rear axle into a front axle! I for one have no where near the money to have this done but I thought It would be a cool thread to start up! What do you guys think?

I'd have to say if your going to all work and expense to weld on knuckles then why not just flip the hog head over then it runs the other way? I mean if your having axles cut your not worried about a little overfilled oil level are you??

if I remember right from reading past questions about this, flipping a rear axle over to make a front axle leads to oiling issues and burned up bearings.  though it might work if you never go faster than 10 mph or farther than 1/4 mile at a time (ala what incommando said).

This is not unheard of in hardcore wheeling. 9" ford and 14 bolt GM center sections are popular options.

I didn't think about reverse gears at all! That would be a problem. Oiling would be too, it would be a cool project though, although not worth it.

The axle does not need flipped. If you run it upside down, the wheels would spin backwards. Trust me on this. If you don't believe me, take a spare rear axle, spin it around 180 degrees (WITHOUT FLIPPING IT OVER), and turn the driveshaft in forward direction with regards to the direction the truck is facing (which would be in reverse relative to the axle), and the wheels turn the correct direction.

 

If you want to flip it upside down you'd need reverse cut gears and you'll have oiling problems.

But doesn't the fact that the axles are now pulling instead pushing correct that? They do not make separate gear sets for front/rear if the axle is identical. If the cut on the pinion and ring are the same front to rear then the rotation is the same.   Usually "flipping" is just for changing the dropped side of the diff.? The pinion does not decide the direction the input from the drive shaft does. Doesn't the drive shafts theoretically change that as changing the direction that they face means in function they are spinning the gears set in the opposite direction?  If you check those links, especially the various videos on the 'net, they do not change anything to make a front axle out of a rear axle center section. Just asking.

 

The down side to this in L/P axles is that the gears now ride on the weaker "coast" side of the gears. That is why H/P axles are desirable in the front: it makes them stronger by changing where the pinion puts the pressure on the ring.

 

Again: Just asking. I am not insisting I am right or anything.

What I do know.........

 

For tractor guys who home build articulating tractors......

 

They take a rear dif and FLIP the carrier from one side of the housing to the other side, revering the rotation of the axles. Now they have two rear difs opposing each other, one for the front and one at the rear.

 

I have no idea if that is possible with auto difs..........doubtful, but that is what I was referring to.

 

 

 

 

Find the front dif you want to use and take it to a drive line fab shop and have them build you one for $3K.

 

Or buy a crate D44 for $2K

you're are correct.  I must have been remembering an article on flipping a rear axle to make it a high pinion rear axle. :thumbsup:

I actually put my Comanches 2wd. front and rear end back under my XJ doner after swapping axles just so I can move it around if necesary,and because I still have to pull the tranny and T.C. My wife didn't like the way I had it on jack stands.(I really didn't either)I just flipped the spring under rear end and forced the spring over to fit.When I scrap the XJ I'll just pull the rear out.
