want to get a ford 8.8 for 99 xj
I found a ford 8.8 with 4.10 gears, and I was going to get the bracket kit for it, what else do need to put this on my jeep, like changeing my front gears(stock Dana 30) or anything with my driveshaft. The jeep has a 8" skyjacker lift.

Make sure you get the flange from the drive shaft that's on the 8.8 now. You XJ Drive shaft will fit in that flange to bolt to the axle. The shaft will be close the right length. I assume you have a SYE?
You'll need to re-gear the front axle to 4.10 as well.

The other things you will need besides brackets and flanges is brakes. two ways of doing brakes is to use two right 8.8 soft lines and use your stock distribution block with custom hard lines on the axle. or you can use the ford 8.8 distribution block and make sure to disconnect it from the chassis of the donor not cut it. that will replace your stock block and softline.
Emergency brakes have a few options. aftermarket cables, ZJ cables, or the way I did was use the stock cables and get a few of those cable clamp things form homedepot or lowes then just fold the line over the brake leaver and clamp it on.

depending on your driving style i would have the axle tubes welded to the differential housing instead of how they sit with the plug inserts holding your tubes in.. if your a gentle wheeler then don't worry about it.
ford 8.8's have been known to spin the plug that holds your axle tubes to the diff housing. Aggressive use can shear the plug, My 8.8 luckily had already been welded.
also some people who run the disc brakes in the rear find the rear brakes lock up more easily than desired so a adjustable proportioning valve at your brake booster may be a good idea also...

Ive been looking at kits myself . I like the one Serious put together ( it's got the necessities for getting it under the truck without any BS ) . As far as welding and how you wheel , I'd agree with the others weld the tubes and forget about it . I bought my 8.8 Sat. not putting another .10 in the thirty five !
