I did this with my TE-37
Ford 8.8 Conversion
- 95 & Up Ford Explorer
-Spare Passenger side axle to replace driver side axle in order to center the differential.
*4L10 - 4.10 Limited Slip
*3L73 - 3.73 Limited Slip
Explorer 8.8 Measurements:
Weight (complete assembly w/ brakes etc.): 174 lb.
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).
(The F-150 8.8 is drum brake and width WMS to WMS is 65.5”.)
Hole diameter for ABS sensor in top of housing: .811".
Bolt size (U-joint flange to yoke) is: 12 x 1.75 x 30 mm
Centerline of housing to C/L of pinion difference is 3.875" toward the P/S.
Pinion offset: P/S to C/L of Pinion, 27-3/4" (no rotor on axle), D/S to C/L of Pinion, 31-5/8" (no rotor on axle)
The axle shaft strength tested by Warn Ind:
F8.8= 6,500 (lb. ft.)
Cost breakdown:
JY Explorer 8.8 with posi 3.73 rear and disk brakes: $150 including calipers.
Spare passenger side axle: $15
The shop has done the following work: $600+/-
Narrowed the driver side to accommodate the spare passenger side axle. Doing so centers the diff.
Converted the wheel bolt pattern to 4x4.5 on both axles. Bought Lexus LS400 wheel studs for replacement. (axles can be custom ordered of course)
Re-drilled rotors to 4x4.5.
Welded the leaf mounts to the 8.8 from the stock rear.
Now of course it'll be different if your car doesn't have a leafspring setup like mine, you can check out this thread in http://forums.club4ag.com/zerothread?id=12379
Mind you, I got this done over 5 years ago.
