I bought a 1983 bronco with 4 or 6" lift and 33" tires. on the test drive the clutch slipped then dumped the full load at 4500 rmp and was it ever a scary ride as the rear spider gers left the rear cover to spill out on the ground. well the i found a set of 4.56s to replace the 3.55 and need to help the center section i heard of welding the spider gears and both good and bad but mine are in a million or more pieces so that is out. i seen the lockers and thier high price. i look at spools in the past for another car but i just read son on the mini spools. so if you had to drive this lifted bronco with its 6 cylinder motor to work and weekend play which is better or longer lasting or stronger? I am hoping to get this beast on the road and off the jack stands--the blazer guy laughs at me every night when he drives past.

if it's your dd a locker might be a better idea than a spool. it'll save tire wear at least, and should work just as well off-road

best damn thing you can do with a 8.8 is weld the spiders to the case.
I've seen a half dozen do exactly what you described, with stock tires and motors..
The spiders and cross pins are a huge weak link in them.

or... what you should do.. is spend the $100 on a 9" and bolt it in.
then spend $30 on a mini spool, or $120 on a full spool..

I looked and could not find a complete drum-drum under $300 I was able to find the housing but i would need the whole thing and do not have the extra money. I found a set of 4.56 gears for the front and rear at a great price. I may look for an open rear end this weekend and try welding it gears and swapping them in but if i am going in the ring gear i want to do it right once and not keep going back.

All you need is backing plate to backing plate. the brakes off the 8.8 go right on the 9". The truck in my sig is a DD and the ONLY downside to running a spool is tire wear. If you do go for a spool, the first time it rains go to an empty parking lot and do a couple practice runs, find out exactly when the rear end starts to slide and you'll be golden.

If you keep the 8.8, don't use a minispool since the carrier and crosspin are a liability. Either go full spool or a full case locker like the detroit.

yep, full spool is the way to go. Lockers can be unpredictable and that makes them more scary than a spool to me. A spool is a lot cheaper than a locker, so the money you save will give you enough to buy another set of rear tires. I agree with J-rod and Hoxviii, a 9" would be the best way to go. But if you dont have the funds, then you dont have the funds.

That blazer guy probably has a 10-bolt anyway
