Here we go with some parts and info I have been gathering for the 8.8 swap.... Some replacemnt parts/adapter style parts....
---------------------------------------------------------------------------------------------------
Replacement brake pads (P/N 6674, AutoZone) =$39.99
Replacement Calipers (P/N's C576 &C577, AutoZone)
Replacement Guide pins (2 - H15068, AutoZone)
Replacement Banjo bolts (Ford P/N 385116-S2)
Replacement Hoses (2 - NAPA P/N 380376 & 380528 )=$51.79 E-brake cables (Mopar P/N's 52008904 & 05)
Replacement "T" Hose (P/N 380889, NAPA)
Replacement 2 - Hard Brake Lines(NAPA P/N 813-1208 & 813-1204 )=$6.73
Yoke Adapter (Spicer P/N 2-2-1379, NAPA) I SUSPECT THIS IS CHEAPER THAN @ THE ONLINE SOURCES....
You can also get the 1310 ujoint yoke for the ranger 8.8 (bolt to the explorer 8.8) from a ford dealership for around $28. I had a friend check on this yesterday.
There is also a 1310/1330 combo ujoint floating around out there. Neapco # 1-0134. It is available from rubicon outfitters for $21.95 RE1823
(does anyone happen to have a napa part number for this?)
Replacement Yoke bolts (Ford P/N N800594-S100) I belieft these are 12mm 1.5" grade 5 bolts..... not certain though :rolleyes:
Now I figure that the yoke adapter from ford and napa are probably the same part number and will make the 8.8 as close to bolt in as it can get.
The explorer 8.8 will have the 1330 ujoint yoke on it. same as on the cryco 8.25 rear found on the xj's. You could use the 1310/1330 adapter joint to just mate the factory yj shaft to the 8.8 then....
Here is stuff I found in the google cashe of the tj section of JU.
Ford 8.8 specs:
Weight (complete assembly w/ brakes etc.): 174 lb.
Drivers side Ford brake hose #: F5TZ-2282-A

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). (this measurement is 2.5" more offset to the P/S then a TJ Dana 35).

L - Limited Slip Differential
C - Conventional Differential
Thanks Chris Overacker for the specs and measurements! see his website link below.
How many splines are the axle shafts? Standard axle shaft for drivers side is 31 spline for 97 & up Mountaineer, 95 & up Explorer, 30-1/2 inch length - 5 X 4.5 inch lug pattern.
Standard axle shaft for passenger side is 31 spline for 97 & up Mountaineer, 95 & up Explorer, 27-5/8 inch length - 5 X 4.5 inch lug pattern
Can I get 35 spline shafts? Yes
Do I need a slip yoke eliminator? In my opinion, yes
Can I use my drive shaft that I bought for my SYE/Dana 35 set-up? Yes
Is the 8.8 narrower than a Dana 35? Yes but not enough to make a difference when running most aftermarket wheels.1.5" shorter or so. It doesn't matter unless you try running stock rims w/12.5 or wider tires.
Are the 8.8 shafts stronger than Dana 44 shafts? Yes, also the bearings, pinion and ring gear are also much larger.
Will I need that brake proportioning valve "thingey" from a Rubicon? Maybe
Does the 8.8 offer more ground clearance over the Dana 35 and 44? Not under the differential but the bigger axle tubes lift the rig about 5/8 ".
Is there welding involved? Yes, but the new brackets you put on are much stronger than stock Dana’s.
Where do I get brackets? TeraFlex, M.O.R.E., Rubicon Express (to name a few).
Should I weld the axle tubes to the cast housing? I would if it had been salvaged from a wrecked rig. If it is new on a crate (in my opinion) don’t bother.
Will my stock sway bar work? Yes, with a minor modification to a pinion gusset.
Do all 8.8s come with a limited slip? No, read the tag on the housing or remove the cover.
Where is the gear break for lockers? There is no break. Same locker for 3.73 to 6.14
Do I need a notched cross pin? Yes for 4.56-5.13 to clear ring gear (unsure about lower gears)
What year ford explorers do I look for as a donor for 31 spline and disc brakes? 1995 to 2001.
What is so great about 8.8? Parts are everywhere, as in axle shafts, covers, brake parts etc..
What's not so great about the 8.8? Weak stock carrier, replace with a carrier type locker like ARB or Detroit (not a lunch box type) this will cure the problem.
Spun axle tubes: Simply weld the tubes into the diff housing before they spin. You are welding to cast steel so now would be the time to ask for a professional's opinion. I have heard of guys tossing the works in a oven before welding, some just go at it cold. Both say their way is right.
Thin stock diff cover: Get some armor.
(my axle was new surplus and had not been in a collision, i know exactly where it has been from mile one and it is not welded. I dont believe my wheeling style will cause me problems, however i do keep a close eye on the plug welds.)
What kind of locker can I get? Anything like a spool, mini spool, Detroit, ARB, Eaton limited slip….
What is the bolt pattern? 5 on 4.5” just like stock TJ/YJ wheels.
Will my Jeep lug nuts fit the 8.8? In most cases, yes.
What do I do with the speed sensor? leave it in place.
Where to buy? Car-part.com www.ok4wd.com wallysheata, Ariel Performance, www.alljeep.com www.rockequipment.com to name a few.
How much do they cost? Free to $1500.00 but you can find them new for around $500.00 in their stock form complete disc to disc.
