This is just a Ford 8.8 tech dump off my lap top. DJ had some questions yesterday. I have a lot more information on these axles I dug through it to find the most relevant stuff. Post up any questions
What year ford explorers do I look for as a donor for 31 spline and disc brakes?
1995 to 2001.
These are the codes you will need when out shopping for your 8.8
Axle tag codes:
3L73 = 3.73 LS
4 10 = 4.10 open
4L10 = 4.10 LS
and so on
Door codes:
43 Open 3200 3.08
41 Open 3200 3.27
42 Open 4.10
46 Open 3.73
45 Open 3200 3.55
D4 Limited Slip 3200 3.73
D2 Limited Slip 4.10
L73 Limited Slip 3.73
Here's all the specs, measurements, and misc crap about the 8.8 you'll ever want to know.
Ford 8.8 specs:
Weight (complete assembly w/ brakes etc.): 174 lb.
Axle shaft strength: 6,500 (lb. ft.)
Drivers side Ford brake hose #:F5TZ-2282-A
Passenger side brake hose #: XL2Z-2282-AA
Bolt size (U-joint flange to yoke) is: 12 x 1.75 x 30 mm
Driveshaft Flange: Spicer Part Number 2-2-1379
Measurements:
O.D. of tubes: 3.250".
Tube thickness: .250" (some are .188”!)
Ring gear diameter: 8.800".
Ring gear bolts: 7/16" dia. (qty. 10).
Pinion diameter/splines: 1.625 / 30.
Axle shaft/splines: 1.320 / 31.
Rotor thickness (where it mounts to axle is .250").
Overall width 59.625" (the F8.8 is .950" narrower then a TJ Dana 35).
Hole diameter for ABS sensor in top of housing: .811".
Centerline of housing to C/L of pinion difference is 3.875" toward the P/S.
The axle shaft strength tested by Warn Ind:
F8.8= 6,500 (lb. ft.)
D44= 4,600-5,000 (lb. ft.)
D35C= 4,000-4,300 (lb. ft.)
COT: Continuous output torque rating
MOT: Maximum output torque rating
(Numbers from January edition of Fourwheeler, page 60.)
Dana 35 rear axle COT: 870 MOT: 3480
Dana 44 rear axle COT: 1100 MOT: 4460
Ford 8.8 28spline COT: 1250 MOT: 4600
Ford 8.8 31spline COT: 1360 MOT: 5100
Dana60 semifloat COT: 1500 MOT: 5500]
One thing to note is that the 8.8 uses a pinion flange instead of a pinion yoke like most Dana axles. Spicer makes adapters (called "flange yokes") that connect this flange to larger 1330-style U-joints (1994-95 YJ's) or smaller 1310-style U-joints (most other XJ/YJ/TJ's). The 1310 yoke is Spicer part number 2-2-1379. The 1330 yoke is P/N 2-2-1369. I'm told that the stock Explorer driveshaft uses a 1330 joint, so you can grab the adapter from your axle donor if that's the size you need. These adapters bolt to the pinion flange with 12mm x 1.75 thread bolts. The 12-point factory bolts are Ford P/N N800594-S100. I picked up four 25mm-long, grade-5 bolts & lock washers from the corner hardware store.
