need 4x4 help

--------------------------------------------------------------------------------

my problem for the last two years is my 4x4 lights come on and can hear it "click" but front wheels never spin "drive" if i go into low i can feel the gear ratio or whatever change but still doesnt light up the front tires now the both lights work properly and i reset the computer in the back behind the panel by unplugging the two connectos and pressing the reset button and the led flashed 4 times so i know thats good...i'm almost positive the shift motor is good because i have swapped it three times with the same problem...someone told me its probably the hubs and to turn the front shaft by hand and i did and the first two turns i can hear a "click" then the click stops but both shafts turn so it "should be working" can i just clean my hubs? i was told the springs wear out is that really true cuz a dudes trying to sell me his hubs off a bronco II i belive what are used hubs worth? new? any help would be greatly appreciated i only have time to fix it tomorrow otherwise could be a few weeks and its getting cold and NO GARAGE
!!! what do you think? am i safe getting the hubs if theyre known to be good and how do you know where to line them up when installing used ones since if this is the problem the old ones werent installed in the right position if that possible...sorry so long so whats up guys?

It's the auto hubs. Try cleaning them first, they may start working again. Search for a tutorial, it's around here somewhere.

Of course the ultimate fix is manual hubs, but you lost the convenience and a couple hundred bucks.

thanks man

how much do new ones go for? is it worth buying known good used hubs? whats a good price and i cant find that turtorial

 

[92xltcobrastatus]

anyone else have an opinion?

 

[MrShorty]

turn the front shaft by hand and i did and the first two turns i can hear a "click" then the click stops but both shafts turn

Assuming the wheels aren't turning with the axles, this is a dead ringer for bad hubs. You can try cleaning the hubs, as sometimes the buildup of grease and such is what prevents them from engaging.

Bronoc II's, except for a few in '90, used a Dana 28 front end, and the hubs off a D28 won't fit your D35.

I don't know what the going rate for new auto hubs is nowadays, but, when I replaced mine, it was about the same price for one auto hub as for both manual hubs.

If you can get a pair of known good used hubs for significanlty less than the price of new manual hubs, it might be worth it. Otherwise, I'd say get manual hubs.

hey thanks but another question...

will it be obvious when i try to install them that they dont "fit" or will they just not work...just wanna know before i get there throw them on and go home not fixing the problem...are they a different SIZE? And yeah i can continously turn the the front shafts but i'm doing it with the tires on the ground but it doesnt "lock" but for them to lock would the button need to be on and actually have them "engaged" any clarification would be great you guys are smart...i'm small youre BIG :THANKS FOR ANY HELP

does anyone know what years bronco II used the same front end?

 

[MrShorty]

Dana 28 is smaller, the hubs won't even physically fit. The only BII's that would have a D35 (from the factory), as I indicated above, would be a '90, and then it's unlikely (they still mostly got the D28). (Disclaimer: it's possible on any year BII that someone has replaced the D28 with a D35.) So, it will be obivous that they don't fit. Also, Dana 28 has a different number of bolts on the pumpkin (I think it's 12 where your D35 has 10, but can't remember for sure).

And yeah i can continously turn the the front shafts but i'm doing it with the tires on the ground but it doesnt "lock" but for them to lock would the button need to be on and actually have them "engaged"

No, the hubs are purely mechanical, they don't know what position the t-case is in. If the axleshafts spin, the hubs should lock. If the axleshaft spins without the hub locking, the hub is bad.

I fought with my auto hubs for two years, before I switched to manuals. Christmas is comming soon, ask for a set. You also have to get the conversion kit too. http://store.summitracing.com/egnsearch.asp?N=700+400059+4294908331+4294907830+115+4294924927

Pull, clean and inspect your autohubs. Lots of people skip this easy, obvious step and go straight to part-swapping, but 99% of the time the hubs are fine and are just sticking. Unless you're doing some serious off-roading, you don't need manual hubs.

When you pull the hubs, it should be obvious if there are broken parts. If not, just clean them out (use parts cleaner, toothbrush, and lots of TLC). Be sure to remove ALL grease. When clean, fill them with ATF and let them sit (at least overnight). While they are soaking, clean the spindle parts of all grease. After soaking, drain the ATF and reinstall the hubs.

EDIT: When you are cleaning the hubs, you can press in the mechanism and see if the spring returns properly. This Should be obvious when you have it apart. You may have to do a lot of cleaning before the mechanism will move in-and-out, depending on how bad the gunk is...

The number one culprit is grease, which attracts dirt, and gums up the works. The thin coating of ATF is all the lube you need.

Hope this helps.

so what parts need lube

so after i get all the old grease out what do i "lube" with the atf...so just tranny fluid lubricating what parts exactly man? i dont want it to go out again (i'm in wisconsin) and the explorer in snow without 4x4 driving 30 miles to work is a rough rough day when it snows...and i was told if you put them on in the wrong position you "break" the springs and whatnot...but thats coming from the guy who wants me to buy his auto hubs any help in this would be deeply appreciated and save me money

 

[mikeinri]

You should search this site. There is a pictorial on how to rebuild the autohubs (to replace the bearings, which is rarely needed). Anyway, that pictorial will answer all your questions about which parts move and why, etc.

The key thing is to get all the old grease out of the hubs and off of the spindle parts (cams, etc.). To lube a clean hub, all you need to do is put it on the floor and fill it up with ATF (you can depress the spring if you want to be sure the ATF is working through the gears). Don't worry about lubing anything on the spindle, just clean the parts.

sweet thanks man

Also, you might need to remove, clean and reinstall your hubs every few hundred miles if they are worn enough to not stay engaged. Your wheel bearings throw grease into the hub assy and this is why you need to clean them often once they are worn.

As others have mentioned above. Your hub assy. must be clean to ensure proper function.

Some people that do not understand auto hubs will pack them with grease, obviously, this is incorrect!
