Hey guys I'm currently trying to plan out an 8.8 swap into my YJ and am hoping to get some input/direction on what to look for. My plan is to find an 8.8 with disk brakes and 4.10 gears, in addition I will grab a Dana 30 from a 4banger and swap that upfront so I don't have to re-gear. I guess my question is what 8.8 have you guys used? where did you find it? and will anyone be able to help me out with the build seeing as I do not have a welder and am a complete novice when it comes to axles. I am in no rush but would like to try and get the swap done before summer. Will provide beer and pizza when the time come to do the swap. Thanks in advance.

Hey there, I am in the process of doing the same. I do have a 4.10 dana 30 for the swap and I am hoping to pick up the 8.8 4.10 LSD this weekend, as long he dug it out of the snow by then. Do you have an SYE and CV driveshaft yet? So you need a diff from a 95-01 explorer. They make kits for the "hardware", ruff stuff, M.O.R.E., advance adapters. Rock has done the swap and wheels his rig HARD, and the YJ just takes it running 36 inch tires. I do know there was a guy on a Facebook post selling a 4.10 rear for $300. I'll check if he still has it.

Thanks for the reply chuck, I currently do not have a SYE and plan on doing the SYE along with a new tom woods driveshaft when I do the axle swap. If he still has the 4.10 for sale I'd definitely be interested. As far as the Dana 30 did you go HP30? I would also like to do lockers in the front when I put the new 30 in.
-
Yes sir, HP30 from a 4 banger. He said that he has a buyer, but Iit is buried under 3.5 foot of snow. If his buyer flakes I will have him let me know. There is also a junk yard in Higginum that sometimes has them, and Tom's in Worcester always has them.

So I purchased the more conversion kit along with the adapter to go from the 8.8 to the driveshaft ($200 shipped). I guess in addition to leads on an 8.8 if anyone knows about a Dana HP30 with 4.10 let me know. Besides the adaptor and new mounts is there naything else I need for the swap? my ebrake doesn't work so i'll worry about the cable once the new axle is in. Thanks in advance

Here is my two cents...
Do not get the LSD, it is great on paved roads but useless on the trails! it's also a different carrier so if you ever want to add an auto locker you will have to change out the carrier, if you plan on going with a selectable locker then you will be changing out the carrier anyway... but an auto locker in the rear is fine!
Installing one in a YJ is pretty easy you will need to cut/grind off the ford leaf spring perch, install an aftermarket one and bolt it on your springs, adjust the pinion angle before tacking welding it on the axle tube then remove it and weld it on for good. As the 8.8 is a flanged yoke, you also need to get a 1310 flanged adapter that will match your drive-shaft u-joints. You also have to weld the tubes to the center diff section as the factory plug welds are weak and you could spin them. make sure you get a disc brake one from a 99 or newer explorer, it is almost the correct width, (1" shorter), no changes to the brake system and it is easy to connect your existing emg brake cables.
Like Chuck said, I wheel mine hard, with 36/13.5/15's and I am still running stock shafts!
Yes any 4 cyl. JY axle will be 4.10 gears, it is a great axle but you should lose the axle disconnect and upgrade to a solid shafts out of an XJ (bigger u-joints) or if you want to drive like me than you need chromoly shafts!
-
Thanks rock. Going to pickup a locked Dana 30 with 4.10s tomorrow so just need to find an 8.8 now. I'm going to start calling junkyards tomorrow. After I pick one up I'll definitely need some help welding seeing as I don't have a welder. Anyone have a setup to set pinion angles and weld? I will also be doing a SYE and new Tom woods driveshaft
-
So I think I have sourced both axles, going to hopefully grab them after work. Getting the 8.8 from a salvage yard, came out of a running explorer so hopefully won't need anything other then the perches burned on. Grabbing a Dana 30 with lockers and 4.10s from a guy parting his jeep out. The plan was to do this slowly but luck would have it I've managed to find both is a few days.... now I just need to make some friends with a welder ;D hint hint
-
Do you have a 220 outlet in your garage?
-
I do not, I figured I'd have to go to someone house, I do have 220 for my dryer but would need a 220 cord to run to the garage
-
Success!!!! Picked up a clean complete 8.8 ($175) then went to pick up the Dana 30 with 4.10s and a locker ($175) the best part is I was able to pick up a brand new bf mud terrain 33x12.5 and a new black steel rim, TJ fender flares, ss front brake lines, Radiator support, tcase shift boot, prop valve all for $125!!!! Best day ever

Rock and I have a very similar set up, too bad my Jeep has been in storage for a year and a half....
If you haven't ordered the drive shaft yet, I high;y recommend going with a 1330 U-joint on the axle end. Explorers use a 1330 so you can use a stock Explorer yoke adapter and if you ever break the ears off you can pick one up a junk yard or from a Ford dealer. If you go with the 1310 adapter and you break it you will have to order it online and they are a lot more expensive. The 1330 is marginally stronger too.
I broke my 1310 U-joint, broke my adapter and the ears off the end of my drive shaft. I went to drive shaft shop in Montville, purchased a new end for the drive shaft for a 1330, bought a 1330 U-joint from them, went to the Ford Dealer right there on RT 32 and for ~$100 I was fixed and back on the road.
When I did my 8.8 my biggest problem was shock alignment. I ended up going with the Tera-Flex bar which tilted the shocks inboard and it flexes very well. Don't forget to factor a diff cover into the costs because the Ford diff cover is about as thick as aluminum foil. IMO Solid is the best bang for the buck.
-
Thanks for the reply Kurk! I have not ordered the driveshaft but I already purchased the adaptor so I will end up running the jeep driveshaft. The plan is to do a SYE the same time as I install the 8.8, I plan on getting the SYE and new driveshaft together from tom woods. As far as all the alignment issues I'm really hoping to get some help with this and would like to take measurements off of some1 that has already built the 8.8 and I know I will reply heavily on the group to help me out. Also I already purchased SOLID diff covers for the front and rear ($150 shipped)
-
Alright need some advice... technically there is zero rush to get the axles installed seeing as my current setup works fine. I have an issue where I tend to rush things and I really don't want to do that with this build seeing as it will be in the jeep for as long as I own it. So below is my plan, let me know if there is anything I should add to the list, I don't mind spending money on good parts... my wallet isn't a bottomless pit but I do have money set aside for this jeep.
Ford 8.8 out of a '98 explorer (not sure if it's LSD or not yet, has 4.10s)
MOORE hardware (purchased)
Splicer adaptor (purchased
CV Driveshaft from Tom Woods Driveshaft, with this I plan on doing a SYE
New brake pads, lines ect
POR 15?
Now stuff I'm not sure about:
Should I just replace the rotors/calipers? they seem to be in good shape but for $200 is it worth just getting new
I do not plan on touching any internals other than changing fluid and adding a SOLID dif cover. Should I be changing anything?
Finally should I just wait till summer when it's warmer out to do this or struggle in the cold? I do have a garage but its a little crowded with the jeep and misc parts and no heat :'(
Any help is appreciated!!!! thanks!
On another note I need a bigger garage.....

Since you're not in a hurry I'd wait for the actually install until it's a little warmer. You can start prepping by cutting off spring perches, sanding/painting the axles if you want to, adding the diff covers, putting on the flange adapter, etc. If you decide to get new brake parts you can go ahead and do the brakes ahead of time also. It will save you all the little stuff at the end.
I just got my axles in last Saturday and now it's time for plumbing the brakes, tightening everything up and remembering to tighten everything as I go since we stuck everything in loose for now just to put it on wheels.
-
like Kirk, I also changed to the 1330 ujoints after breaking the 1310 adapter so be prepared.
Like Roger said start prepping the axle now and when the weather breakes you'll be ahead of the game.
as for the brakes, if they are decent I would run them, they are easy to change out later and you can focus your money on needed things.
pick up the Lube Locker gaskets, they are worth it, I have opened my diff's too many times to count and the gaskets are still good!
don't bother with POR15 on the axles they will never rot out! a good rattle can paint job is easier to touch up as well!
-
I'm going with the 1330 8.8 adapter flange right off the bat with mine.
-
I just purchased the lube locker gaskets. Yea i'll probably just rattlecan the axle, the dana 30 looks like it has a rubber undercoating on it so I'll probably just leave that one alone for now. When you guys did the swap did you do any additional upgrades (i.e steering)
-
The stock JY steering is pretty strong, unlike the TJ or XJ steering which are notorious weak. If you are leaving it spring under than you should be good. if you where going to go spring over, then there is a lot that needs to be done!
When I when through my axle I added axle tube seals, chromoly shafts, blank off plate on the axle disconnect, new internal seals and new ball joints. the brake were decent and they are a wear item so I left them along and waited to replace the pads when they got low. I also left the unit bearings alone and waited for them to fail before changing them out. I have bigger tires so I wear them out faster, I would say I get about a year and a half out of one.

Or 500 miles. Witch ever comes first LOL

I am going to pick up my Open 4.10 8.8 Explorer rear from a 99 Exlploder sport tomorrow morning at the scrap yard in Higganum. I ordered Lube locker gaskets for the 8.8 and the D30 that I picked up with 4.11 gears. Ordered the 1330 flange adapter, bought an SYE installed in a case that I have to swap into mine and Tom Woods Driveshaft from Roger. I am also picking up a TJ one piece passenger axle shaft and will make a block off plate. Anybody have a Dana 30 locker or 8.8 locker?

I did the tie rod flip when I did mine. It was a little scary drilling through the knuckle and finding the right drill bit wasn't easy....but the end result is worth it. Tie rod sits ~3" higher (doesn't hit rocks as often) and better steering geometry (less bump steer).

Just wanted to post up and let everybody know that I picked up an 8.8 today with ford racing 4.56's, LSD with ford racing kevlar clutch's and brand new brake shoes for $180 from a scrap yard in terryville. And no it's not for my samurai.

Nice score, what is it out of? Mustang?

Nope mustangs are 28 spline (eeeeek no good) It was in a 4x2 1985 f150
-
I was thinking Mustang due to the racing clutches. Now that we know what it came out of I think I know what it's going into. ;D

You would be correct in assuming that lol. On thursday during lunch I was on my way back to work and I noticed my abs light flashing and my speedo was bouncing around like crazy, which I just figured the speed sensor was failing.... Nope I was wrong about a half mile from the shop, I left a stop sign and when I let the clutch out in 2nd and I heard probably the most unpleasant sound you can here from a vehicle (other than a rod knock). The passenger side carrier bearing race had actually been pushed a 1/4" out and the carrier was just moving around as it pleased in the housing. I never heard any noise from it because the boggers are so loud going down the road. But anyway the truck it came out of (which I wish a saw) was probably a project truck for drag racing I see a built 302 or 351 with a c6 behind it thinking about the gears and LSD thats in this axle.

I did this as well! I also did a steering pump mod to increase flow (I did not increase pressure) and added a cooler, power steering works much better!

I changed over to the 2001 XJ power steering pump when I did the intake manifold swap and added a power steering cooler from a late 90's ZJ. I also added a brake booster from a 2004 TJ and the braking became much better as well.
