Jaxon1023 Threw on a riddler diff cover

O_M_Jeep If you read the thread there are a few answers to this question.

hoprocket Thanks will stay with 80/90 w and change at 500 miles

Jaxon1023 GEAR OIL: THESE AXLES ARE SHIPPED WITH ASSEMBLY LUBE ONLY. FAILURE TO ADD GEAR OIL WILL CAUSE IMMEDIATE FAILURE AND BE VERY EVIDENT. ALWAYS FILL FROM FACTORY FILL HOLE NOT AFTERMARKET COVER FILL HOLE. We recommend Lucas 85w/140 gear oil, Lucas 80w/90 gear oil is also acceptable. We do not recommend synthetic fluids. IF you have a factory limited slip or any clutch style limited slip a limited slip additive will need to be added. TRANS-X makes a good additive that is available at any auto parts store and we also have it available for purchase.

Jaxon1023 500 miles and I read on ECGS that synthetic gets to thin with heat

Thanks! I'm actually heading home now to take another stab at it.

hoprocket Just finish install of my 8.8 and love it . Went in so easy and braking is better . One question how long or how many miles should I let it go before first oil change in rear end ?? I thought I read 500 miles and is it worth it to go with synthetic oil ??

Ryan Angela Hoping someone can help me out here. I'm getting ready to install my ZJ parking brake cables, and I cant seem to find the route. Does anyone have a pic of their completed set up showing the cable route?
10-03-2014 09:31 AM
Ryan Angela Absolutely. Just about all the information you'll need starts on the first page of this very thread. It's a lot to take in, don't rush through.
10-03-2014 09:22 AM
8505jeeper Is there anything you should look for when considering buying an 8.8 axle? I've found some pretty cheap but I'm new to this so I'm not exactly sure what to look for.
09-30-2014 06:11 AM
Martin_N After a lot of work mine is ready to go under the Jeep

After purchase:

And how it looks now:

Hope to pick it up in few days with the new axle installed and all checks needed for road legal use done.

Can't wait

Stephen Taylor Awesome thanks. I'll be starting this project shortly and I'll have pics of the build and the finished project.
09-27-2014 08:29 PM
Ryan Angela That's the same set up I recently finished. Fits well. The 8.8 is slightly narrower than the d35 it replaced, but I already had wheel spacers. The only questionable area on mine, in terms of fitment, is the Ruffstuff diff cover. At full or near full bump, it rubs my gas tank skid very slightly. It's only enough to rub the dirt off, but I haven't got serious with it yet either.
My e-brake cables, that's what I'm struggling with right now. I have ordered a set of ZJ cables, I'll see what I can make of it when they show up.

Stephen Taylor I now have my ford 8.8 and I'm looking into a truss kit with all the needed brackets. I am currently using the RC 2" lift and my goal
Is to run a 33" tire with my existing lift an flat tubed steel fenders. With the 8.8 with the truss kit fit with only a 2" lift?
09-17-2014 05:28 AM
Jaxon1023 Mine worked perfect
09-14-2014 08:56 PM
GoldenSahara00 They are pretty darn long. I had no issues with 3"
09-14-2014 08:51 PM
O_M_Jeep I'm curious if the e-brake cables will work with a 4"+ lift
09-14-2014 08:25 PM
Jaxon1023 Yep that's it

The kit I'm linking and posting the site pic of is Artec truss specific.

Jaxon1023 Got mine all welded up with 4.88 Yukon gears and spartan locker.

Sheklikak I guess I didn't know the answer
08-06-2014 10:25 PM
GoldenSahara00 Plug the stock hole with weld. Drill and tap a hole on top of the diff and screw the old breather plug in.

Yes you will notice it. Add a taller coil or spacer to the front or add some weight to the rear in the form of a bumper or tool box. Or lighten the front somehow to help.
08-06-2014 03:17 PM
Sheklikak I already know how I sound, spazzy, but I'll ask anyway. Just some background; I wheeled with a D30/35 set up on 31's. A rougher trail than anticipated resulted in my TJ being towed home. It was just a bent main in the TC, but one thing lead to another and about 8k later I have several mods including the Ford 8.8. One special thing that I noticed is that the jeep sits like a 70's hot rod, all jacked up in the back.

Now I know that the 8.8 sits the frame about 5/8" to 3/4" higher (depending on who you talk to) but I feel my 6yr old RC budget lift springs are sagging. I was thinking 3.5" MC dual rate springs for it's smooth ride and I don't want to add a coil spacer to equal the jeep out.

My question is (and I think I already know the answer) will I really notice the slightly higher back end?
08-06-2014 03:14 PM
obidya Probably a dumb question but.... I've been lurking here but am finally starting to fully assemble my own 8.8 for the install.
When lining up the truss kit we had to block the stock breather. Is there a preferred size or location for that or is it just as simple as a hole I can run a tube to? What about some of the "not used by a TJ" bolt holes on the top of the pumpkin, can I just drill that out and run a 1/4"npt there?

Wondertwin1 Are there any brake kits out there to replace the old junkyard lines and hoses with? The old line doesn't mesh up well with my artec truss.
07-24-2014 04:56 AM
GoldenSahara00 Zero issues for me... But my exhaust dumps out under the pass door. Ran a new cat and high clearance muffler (hush power II) for the tummy tuck and gave me a ton of room. I feel confident however that I could have run it to the stock location.

I wouldn't change diameter but run a smaller muffler if you still have the stock one. The diff offset is very little and honestly I don't think you'll have an issue.

O_M_Jeep Wow, about 75 minutes to read this whole thread, I'm surprised at how many people ask questions that are answered several times in preceding pages, anyway, I just got my 8.8, out of a '99 Exploder, and it was clean and and a nice axle to start with.

I have wheeled my Š-35c very hard over the years, alloy shafts, Superior truss, Tru-Trac, 4.88s, and 33"s. It's worked so well for years, never an issue, but lately I find myself, late at night, to my shame, on TireRack and 4WD and other sites stealing looks and pricing 35"s and 37"s. So the Š-35c has to go, a sad day, but I'll sell all but the housing and brakes to someone who is making a trail capable DD.

I'm planning to do a ton of work on this install, Tru-Trac again (I love it where I live, snow & ice 9 months a year), truss, triangulated 4-link, air-shocks (coil-less coil-overs), fuel cell and back half.

I'm curious about just one thing (to start with anyway), I'm reading the off-set is not a huge deal, Stu Olsen covers it very well, a brazillion thanks to Stu and his contributers, but I'm wondering if I should relocate the exhaust and maybe change to a smaller diameter muffler to avoid any interference, I only saw one person post in here that the u-joint was rubbing the muffler, but I hate to find out at the last minute.

I am planning long arms and a small stretch, maybe out to 100", so I think that will solve the proximity issue (if any). Has anyone noticed any problems with the 8.8 housing being off-center?

Thanks for the input.

This is what I found delivered to my house one day, $250 for a complete assembly.
