Hi again, I have a 78 Bronco with built 400, and rebuilt c6 tranny, swapping in the NP205 transfer case. The axles that are on this rig are shot. The front axle was under water for many months with the front pan off, and the rear had sludge in it when I checked the fluids.
My feeling is to replace both axles, and in doing so, I'd like to put the best ones on I could, within reason. The use for this rig will be mainly only for camping trips during the summer, and will not be off roading all that much. Will probably get into mud now and again, but nothing serious like rock crawling, or being hood deep in mud pits. I don't know much about gearing or anything, but when on the road I'd like the thing to be able to take off fairly quickly and have nice acceleration. The engine and tranny are built for it. I just don't wanna get something that will have me red lining top gear at like 65. lol.
From what I have read, the rear axle of choice is the 9", and the front a danna 60. But would like to hear it from someone.
if you plan on running a 35" tire and nothing to much larger just rebuild that front D44. its a great front diff and parts are easy to find not to mention much cheaper then going with a D60 front. a D60 front generally run $1000 and thats in stock form. you would then have to regear and get the proper brackets welded and such so you can continue to run coils up front.
since you have a C6 going with either 4.10's or 4.56 with 35's-37's. if the 400 is built right it should get you out of your own way just fine.
Lockers are great but honestly ive been running open both front/rear now for 2yrs in my bronco and havent had to many times being stuck. but then again i am generally smart about where i am going and i do have a winch in the event i get stuck. a selectable locker would be best if you can afford it like an Elocker or ARB.
So I guess I don't need a locker, but I have decided to install a doubler transfer case. As for the rear end, when I rebuild to 9", since I have the doubler that can give me very low gearing, should I go with a taller gear in the rear end? I know nothing about gearing in the rear end at all.
If you plan on running nothing larger then 35's i would go with 4.10's. a taller gear may help some on the hwy but would suck in town. remember the doubler only helps ya when your in the woods with the 4wd engaged.
When you decide on a lift & tire combination, then you pick your gear ratio. Don't do it backwards, you'll just waste your money.
If it were my '78 Bronco with a built 400, I would go no less than 35's.
Ok, guess I have no clue what the sizes are for tires. For 35's, are they 35 inches wide? What are the benefits of larger tires other than look and for use off road?
The sizing I'm used to is "LT235/85R-16/E1 120S" That's for my 92 F-350.
Now in righting this...... in "LT235" is that where 35's come from?
What would be considered too bid, or just plain ridiculous? lol
