Word on the street when was doing this swap is you didn't need to adjust the proportioning. 3 months later and I've yet to see any problems with my brakes. No sticking, dragging or grinding. And they stop quite well, not sure if I would call it an "upgrade" but they certainly stop the jeep fine.

I built an 8.8 for a '93 a year or so ago, and never had any problems with the disc brakes sticking. I didn't do anything with the proportioning valve, and had no problem stopping the Jeep on 33s.

Just be sure you bleed your brakes real good. Most end up with the mooshy brake syndrome. I did also, then I did a E350 master and after bleeding it real good I finally have good braking. I even removed the prop. o-ring and I didn't notice any change in how it brakes.

Yes the e350 master works b/c it has valves in it that are set up for front/rear disk breaks...

Finished sandblasting ^^

Now I need to make a fill plug of some sort for the ABS sensor hole, paint, install SYE and swap it in!

Waiting for the finale!

I am starting my 8.8 in the morning. Actually, I have been doing all the prep and its being installed in the morning.

Awesome write up, great to see someone put so much attention to detail into their work. Wish I had access to a sandblaster like you do.

Thanks for the kind words! Best of luck in your swap.

Been working on this thing as much as I can but I'm dealing with some serious time constraints as I'm working 50 hours a week and going away to school in two weeks. So much to do.

But anyways, got the second coat of paint on



Installed the shafts and cross pin, everything inside the diff is ready to go. Crappy pics, the humidity was killing me.



Installed the caliper mounting brackets





And the moment we've all been waiting for...







Ready to be swapped

Looks awesome! I definately didn't get that much into detail and prep. The 8.8 is in, minus the driveshaft since my adapter plate never showed up, shocks installed, brakes waiting on a $.99 fitting that the parts store was sold out of. Did the boomerangs on all 4 corners. Jeep sits awesome! Its a bit too high now, 36 1/2" to the bottom of the rockers. I gained about 3" when i fixed the PO screwed up suspension work. The shocks were topped out and actually holding about 2" of suspension.

I am seriously jealous of your 8.8. If you were closer I would pay you to prep mine!

The moment we've all (or at least I've) been waiting for...



I was getting frustrated and decided to just get it done.....apparently that meant staying up until 6 am working in the garage.

Prepare for picture overload....


Jeep in position Sunday morning



New transmission mount while I was down there



Transfer case out



And split



SYE install begins..



Punched holes in a piece of cardboard to remember which bolts go where on the T-case



Me "pressing" off the needle bearings of the drive sprocket thing. This is one of the points that I was worried about going into this project. It sounded confusing and I didn't have a press but once I saw what I had to work with it was very simple. Moral of the story, don't fear the SYE.



SYE mostly installed



Finished



Bolted back up (Sunday night)



The 35 coming out for the last time (Monday night)







(Yes I know my garage is a hideous mess. Its a crazy time in my life)

Springs bolted up to the 8.8





Tires on





Ready to roll under



My brake setup...I needed to extend the hard line so the soft line would come down centered on the axle. Welded a piece of angle and relocated the mounting plate for the hard/soft connection



And installed! (In the wee hours of Tuesday morning) Sorry for the crappy pics again, it was late and blah blah. I'll take better ones if anyone wants to see more detail







Pinion angle...I might shim it







Its what I get for guesstimating...what do ya'll think?
