My factory axle in my 2001 single cab 4.0sohc, 4x4 is an 8.8" 4:10 TracLok limited slip with drum brakes. It's a rare truck in a single cab 4x4 with the 4.0 and was special ordered. I've seen less than 8 or 9 of these trucks equipped this way and I've been in the Ranger community continuously for over 25 years. But lots of Rangers came with "small bearing" 8.8" (28 spline) with drum brakes.
"Ford Ranger 8.8-Inch Axle Usage:
Ford began using the 8.8-Inch axle in Rangers around 1986 on 'incomplete vehicles' aka 'chassis cabs', but the 8.8-Inch axles didn't become common in the Ford Rangers until the introduction of the 4.0L V6 in mid-1990. All 4.0L Ford Rangers are equipped with 8.8-Inch axles."
1998-2011 4—4 supercab Rangers regardless of powerplant are frequently equipped with 8.8-Inch axles. We've seen a 2001 Ford Ranger 3.0L with a 8.8-inch rear and 4.10 factory gears.
Ford 8.8-Inch Axle Shaft Splines:
Ford Ranger – The Ford Ranger 8.8-Inch axle used 28-spline shafts. The exception is the 2002 FX4 and 2003-2007 FX4 Level II models which had 31-spline shafts."
A lot of early V6 Rangers of various years also came factory with the 7.5" rear axle. My one owner 89 Ranger single cab has the 2.9L V6, 5spd, manual transfer case, and a 7.5" open diff rear end.
The FX4 LVLII Rangers came with the 31 spline "big bearing" 8.8" with a Torsen limited slip, and drum brakes, for at least two years (02-03) without a doubt. The 02-03 were also the years for the manual shift transfer case. Many other Rangers after 2003 also came with the 31 spline 8.8 axle.
I had a 2002 Ranger FX4 LVLII 31 spline 8.8" shipped to me for my 87 V8 swap Ranger. I wanted the Torsen L/S and 31 spline because I knew I'd be beating the crap out of my truck daily, and I do.
"Ford 8.8-Inch Axle Bearings:
2000 Ford Ranger 8.8-Inch 28-spline axle bearing ID= 1.399″, OD= 2.2948″ (1563 series bearing)
Ford Ranger FX4 8.8-Inch 31-spline axle bearing ID= 1.1618″, OD= 2.5333″ (1559 series bearing)"
"Ford 8.8-Inch Axle Disc brakes: The 2010-2011 Ford Ranger rear axles come with disc brakes."
"Ford 8.8-Inch Axle Width Differences:
1990-1992 Ford Ranger 8.8-Inch Axle – 56-1/2 inches
1993-2009 Ford Ranger 8.8-inch Axle – 58-1/2 inches"
