My sons uncle gave him a 92 bronco that he bought new and it needs a few things done and we want to do it ourselves as a project. He just got his license and this is his first vehicle. Neither of us are mechanics but are mechanically inclined and know just enough to really screw something up, just don't know what we can do or shouldn't do. So we will have some basic stupid questions. It has 229K milkes and is running OK but needs to have the rear end fixed. It sometimes pops when you go around a corner from a stop(ford dealer told his uncle the spider gear needed replaced) It also slips sometimes when you go from a stop if you get on the pedal a little. It sat for 1 1/2 years before we got it so i don't know if the slipping could be helped by flushing the transmission since it sat so long. I have a 93 f-150 in the barn that has been there for several years and we can use it for parts?? Rear end in the bronco is H9(3.55 limited slip) and the truck is 19(3.55 locking) can the rear end from the truck be put in the bronco or does the limited slip in the bronco have something to do with the 4x4. Also, both trannys are type E (E4OD). Can they be swapped straight out or are there other factors that would make them different? Both have a 302. Any help or suggestions would be appreciated.

 

You can swap all of that around if you want. However I don't think the truck is locked. Factory didn't use lockers just limited slip. You can switch rear ends easily since they are both 3.55s.

 

The trans slipping could be from low fluid or a worn flexplate, and the knock sound could be a worn out U-join on the drive line. I would get under and start shaking stuff like your trying to choke somebody to see if the drive line moves. If it does turn out to be the spider gears it might be worth it to swap with the f-150 but you would want to do a flush on that rear end since it sat for so long. I have never done it personally but i helped a friend replace the gears in his suburban once and it really didn't seem that hard it was just a PITA to tighten the nut on the u-joint receiver. It called for something like 200 foot pounds or something, it took 2 larger guys on the homemade breaker bar and 2-3 guys to sit on the axle itself (it was on jack stands) To keep the sucker from moving.

 

Thanks guys, i'll check it all out, spent yesterday replacing manifold that was cracked completely in half. That's fun to get to!

 

Rear end isnt that difficult it took me and my uncle all day to do mine the first time the second time we changed the pinion bearings which didnt take as long but I could tear apart my rear end blind folded now... I would recommend getting a chitons or haynes repair manual, theres alot of useful information there
