88 bronco rebuilding rear
#18
a 9" on your 88 is not problem since the speed is picked up from a gear in the transfer case. If it was newer like early-mid 90's then it would be a different story. But in your case it is a direct bolt in.
For your front, since you are pulling it all down anyways and looking at a 6" lift, then might as well do a solid axle swap and be done with it. The TTB will never stay in alignment with the lift and larger tires so might as well get rid of that aggrivation now. Do a search on here as there are numerous threads about doing the swap. It's fairly straight forward, and if you have any mechanical skills, then you will have no problem getting it done. Worst case, if you run into problems, just ask.

thanks i'll look in to both options i'm not a fan of IFS 44 as far as strength and sevicablity having trouble finding a LSD rebuilt kit w/ gears can't find the gear set anywhere is this a uncommon problem? does anyone know where to get? if not looks like i'm going to the salv yard anyhow so i'll see what kind of rears i can find. If anyone knows where to find rear codes for various bronco/f-series that wound be awesome

If you geta carrier from a salvage yard, the tag on the diff will read something like this:
"3L55" which means 3.55:1 gear and a LS diff. if it says "3 55" then it's just an open diff with the 3.55 gears. the other option is to go directly to Ford forthe side and spiders. It's where I got mine when Ishattered a set.
For the solid front, look for something from a 76-79 F-150/Bronco. The 76-77 diff will be solid tube from center to knuckle and is more desirable, but for normal abuse the 78-79 with the cast in sections will work. Just make sure you get everything from the donor truck, meaning not only the axle but the radius arms and brackets but the track bar and bracket. Your 88 upper coil bucket/shock mount will work just fine.

So if you are thinking of a 6" lift and will be in the axles anyways. What gears are you looking to go with? Might as well do that while you are in there. Any idea of what size tire you want to run? I know that with the 6" lift on my 95, I can clear 38.5.x11's but if they were any wider I would need to trim the front fenders. 36's however fit no problem.

So in other words, it's mostly a street pounder with occassional offroad. In that case go with the 4.10's for a 35-36" tire. As long as you put it in low range it will do fine. If it were more toward the mainly offroad side, then I would say 4.56 or maybe even 4.88's. But it would kill your street mpg and your aod would hate you for cruising rpms.
