Explorer rear axle swap

**doghows** · December 1st, 2016, 08:34 AM

I didn't even think to take a pic before I cut it but yes it was definitely offset from the explorer.
I'll stuff it in this weekend for mock up and click a couple pics.

Doesn't the explorer use a CV joint type of coupler on both ends of the driveshaft rather than U Joints? I would think the CV type is more forgiving with multiple offsets. If so, maybe keep the explorer driveshaft and see if you can get a CV type crankshaft for the transmission.

Of maybe do nothing if it's isn't a big deal.

You got it right Jeff the explorer used a CV on both ends. My local driveshaft shop said well simply put a CV on the axle and and keep the slip yoke on the trans end.
This swap came out sounding way to involved. It's actually a very simple swap and everything lines up just as stock would. All the measurements were the same as the stock axle that came out. There are tons of falcon guys running these rear axles with no issues at all. I got the idea from the guys over at FFOG on Facebook. Some of them are running these with high HP engines and some like me just for the gear ratio and posi.
I'm going to put it under the delivery today or tomorrow and I'll post up some pics. Should have it all buttoned up and ready in about a week or two depending on parts deliverys.
This should really wake up the car going from a 3:00 gear to the 3:73 posi!!

Well it's under there. Sorry for the bad picture but it was getting late and cold. Initial measurements put it dead on compared to the eight I took out.
My new axle should be here any day now so I can put it together and put the wheels on. That will tell for sure if this is fitting or just looking real close. More to follow.

So it looks like you have everything all loosy goosy (nothing welded yet) so you can shift things around, mark it, and then weld everything into place?

Looks like fun. So the center of the pinion seems to be heading down the tunnel OK?

Also, meant to ask. Jeff mentioned CV, but this isn't really CV is it? CV stands for constant velocity:

It's a flange-style yoke instead of a U-bolt style at the pinion end. 4 bolts hold the flange at the pinion yoke and the u-joint is normal on both ends?

Yes the second picture is what is on it.
It is all loose for now roughly measured in. I'm waiting on my axle shaft. Should be here tomorrow. Got all the other parts so if it's not too damn cold I'll get it finish mocked up and tacked in. Looks good so far!!
