8.8 Install

First just gotta say thanks for all the info there is so much knowledge on here its amazing. Just a couple questions all all who have done this swap:

  1. Did you install new master cylinder or proportioning valve or remove existing proportioning valve spring ?? How are the brakes ???
  2. Do I need a slip yoke & CV drive shaft ??

Any additional info is always appreciated.

Thanks,

jeff

I have an 03 TJ. I hooked up the rear brake line hose/t-connection to the 8.8, bled the brakes with a vacuum bleeder and that was it. Brakes work fine. Swapped out the two e-brake cables with ZJ cables, and the e-brake works pissah! Not sure how much your master cylinder differs from mine.

You can confirm with Jay (Freejeep) or AJ (Streetglide) I believe both have done 8.8 swaps on their YJ’s

As far as the SYE and driveshaft, that will depend on the amount of lift you have relative to the pinion angle needed to keep the rear driveline from vibrating.

Can anybody identify this as an 8.8. In was in a 99 ford explorer 2 door. The weight on the housing is throwing me off.

Check the Bolt Pattern on the cover. Scroll down there is an Identification chart near the middle of that page.

The weight is on there for a vibration damper. It can be removed and thrown away

looks like the right one. there should be a tag under one of the cover bolts. unbolt it to check the numbers. you will need a conversion flange ($50ish) or a conversion ujoint- 1310/1330 ($27)

supposedly the flange of a ranger works
or crown has them it just takes Jeff a couple days to get them to canton
good luck, ill be doing the swap soon

unfortunately I could not reach or see the tag. I have already picked up the M.O.R.E install kit (perched & shock mounts), e-brake cables & conversion flange. Can this be done without a SYE ?? I know if i don’t install it now then ill have to readjust the pinion angle later (re-weld or shims). Id like to do a SYE now as well a get rid of the t-case drop but this project keeps growing and funding is minimal.

i think you can get away with it for now.
