hey guys, just joined the forum here after reading for about a year now. love the info, keep it up. alright, for the question, i have an 1986 w250 360/4-speed i am rebuilding/driving. i know scary! i am looking for a complete rear axle assembly, new or used, with either 4.10 or 4.56 ratio. as you know this is an eight-lug pattern and all the junk yards around here have either 5 lug, or they are worn out. this is a 60 diff. i am getting ready to lift 6" and get 35's so i plan to swap axles when doing so. also, comments on suggested gear ratio for those of you who have similar setups would be helpful. thanks ahead. -mike :dtrocks:

I got one, but I ain't parting w/ it :D 4.56 is a bit steep unless you're running 38's or bigger. I'd go w/ 4.10's, that's what mine is and I'm gonna run 35's.

BTW, what are you gonna do w/ the front?

What ratio do you have currently? Can you have the axles on your truck rebuilt, regeared and locker or anti-slip added for whatever you want?

my axles, bearings, everything inside is done. i rebuilt it once already, but the truck had pulled hi-lifts and dozers for 140,000 miles. i'm just ready to replace. i currently have 4.78's that were put in. looking to change to 4.10 as speed dragon was saying. i figure that's probably the gear it'll have when i find one being the common gear in the truck, if it's too fast i'll change the ring/pinion. nothing new there! advise to everyone out there, if you are experienced in diff. work, do not tell your 4-wheelin buddies, you WILL stay busy! lol!

Honestly, if I were you I'd just buy a ring and pinion set and have a good shop install it for you. Probably cost the same or less.

BTW, you do know you'll have to change the front to match right?

yeah, i'm aware i'll have to swap the front. my only reasoning for replacing is this is my daily driver, and the bearings, axle shafts, the whole nine yards is trashed. if i just replace the ring and pinion, then i still have 1/4" lateral play in the axle shafts. the front i don't mind just swapping the gears, but i need a fesh, or at least newer start for the rear.

Have you priced a used Dana? I am unsure what they sell for so I may be wrong on this, I would do like speed said and rebuild it if the housing isn't bent, then you would have a almost a new axle assembly. If you bought a used rear then most likely it would have been used for heavy towing as was yours. Anyway I think the money is better spent rebuilding your old unit just my two cents though. I have a link listed for a rebuild kit that replaces everything but the gears.

most junkyard are selling used rear end (80-100k) miles for about 400, it's just the 200 dollar shipping that's killing me! and i have to have the truck ready to drive to work when it comes time since this is my only vehicle. i just question spending the money involved to replace both axle shafts, axle bearings, ring and pinion, pinion bearings, axle seals, and pinion seals due to the price of everything. i priced the pinion bearings at a local parts store to find a price tag of nearly $60 a piece! that's a whole lot of money to put into an axle for bearings. i'm almost considering a 14-bolt corporate rearend and welding new spring perches on it. what do you guys think?

The kit in the link that I posted was a complete rebuild kit less the gears for $87. I also posted a link for gears thats another $160. Thats $247 less shipping. I don't see the reason why you would want to replace the axles they aren't a consumable part. I would hate to buy a 100k rear for $400 and still have a wore axle. When you could spend $250 less labor and have a fresh axle assembly.

the axles thereself are spun, although i'm liking these prices you've got. for that type of price it's sounding more probable. sorry, my comp. wouldn't open those links.
