No, the 7.5" designation means the ring gear is 7.5" in diameter, 8.8" would be, of course, 8.8" in diameter, so wouldn't fit inside the case.

Good read here on the 7.5": Ford Ranger/Bronco II 7.5-Inch Axle
Lots of ford vehicles came with 7.5", L/S(limited slip) will be the hard one I would think, pretty much all 4x4s came with L/S in the rear, and 3.73 was the most popular gear ratio.


Axle codes from door sticker are here: Ford 7.5 & 8.8 Inch Axle Tag & Door Codes

Ok so I'm looking into just replacing the entire axel assembly. I found a rear axel locally with the 3.73 but it's an 8.5 not a 7.5 like the one I just took out..

Im not wanting to fit an 8.8 into a 7.5. I'm wondering if I can swap the7.5 373 rearend and install an 8.8 373 rear end. Overall length is 56-1/2" in both.

My truck is a 4x4. will it matter if i go with the 8.8 373? instead of the 7.5 373?

thanks

No, that won't matter, as long as the front and rear have the same ratio ring gear size won't matter

That's odd, 3.73 is most popular ratio, and 7.5" most popular size.

Local or semi-local wrecking yard should be able to get one in for you.

All 1983-1992 Ford Rangers used them, '93 and up were wider, but internals were the same, all were 28 spline axles, 4.0l got 8.8" '90-'92, then wider in '93
Bronco IIs '84-'90, used same internals, 28-spline, but axle was longer on 1 side
Most 4x4's had L/S in the rear.

Aerostars('85 and up) and Mustangs('79 and up) also used 7.5", 28-spline although L/S would be harder to find
