8.8 questions

ok so i got an 8.8 rearend and started disasembling it. ive emailed a site named knowhowtojeep or something like that and am getting everything i need for around 430. so what i need to know is do i need that speed sensor thing on the top of the diff, cause all it is is the plug, the wires were cut at the junk yard, what should i do with that. also there is a tube type thing coming out of one of the axel tubes, wtf is it. 95 explorer rearend btw.

welcom to 8.8 world. I have a 1999 TJ and I dunno what that speed sensor thing was all about either. I just left it.

The tube dealio coming out of the axle (drivers side right there outboard of the bracket location) is your axle vent hole. If you take it out you will see it has a itty bitty hole in it about the size of a 6d nail. Some folks relocate it I did not. I just pushed my vent hose down over it. Your current axle has the same thing..it is tied together where the hose goes over the dealio at your brake line splitter.

Is yours disc brakes or drum? 95 Ithink was the changeover year.... Good luck man it is a fun conversion. get your angles right!

Yes I can: How much lift do you have on your jeep? That's the first thing you need to look at. Best way is if you already have your jeep lifted to your desired height... Look at your existing axle. If you need 15 degree pinion angle then set up your new axle pointing up that far...weld on your spring perches at 0 degrees.... and if I am not mistaken my brackets a -5 degrees off from my perches....

I have a 4" rough country lift and my pinion angle is perfect at 15 degrees.. You should be similar with similar lift.... BUT EVERY ONE CAN BE DIFFERENT! - - The truest way is to get it in there and adjust the pa equal to the driveshaft angle.

Yep, 4inch lift. So, should i just use my old axle as a refrence as to how to set the brackets an such on the 8.8. 15 degrees was exactly what i was thinking, negative is down and positive is up right. the only thing i dont understand is, do i need to know the pinion angle ima usebefore i weld the brackets, cause what if i want to get a bigger lift, would i have to unweld them then reweld to change it, or is it based on the length and setup of the control arms.and im prob making it more complicated than it really is

Check this link out...when I did my swap, this guy's measurements were on dead nuts. There are always a chance that things will vary, but this will give you a base.

Make sure to tack everything into place, slide the axle back under the jeep and make sure everything lines up well before burning them into place.
