i need a little guidance, ive searched the threads,but really didnt see my problem. i went to use my 4wd yest, it shifted right in to 4 hi normaly, light came on, and nuthing, no 4wd, no noises. my running gear is all 1986. im going out to drain the oil and general inspect it this morning before we get nailed by the tropical storm. i'll check back in if i find anything, thanks in advance. p.s. not having 4wd is kinda like leaving home without your wallet........ it just doesnt feel right

 

How do you know if it wasn't in 4WD?

You have Hubs that are manual or auto? Is the front drive shaft turning?

 

rear wheels were spinning, front were doing nothing, i have manual hubs, they were locked in, ill go out right now and try it again in the yard to see if drive shaft is turning. are these chain driven?

 

ok, just put it in 4wd, hubs locked in.... driveshaft turns... i shut off truck and reached under there and there doesnt have any funky slop or anything. also with truck shut off, if i turn drive shaft i can see it moving out to my cv joints

 

Hubs are locked, the T-case is in 4wd (hi or lo), on flat ground with no tires in the air and its still spinning the CV axles?
Sounds like your hubs are not locking in.

 

locking hubs are no longer locking... would be my best guess... that's why it's always diagnose it like that... shows ya right where your driveline to wheel connection stops."problem spot"

i would take off yer hubs and check it all out.

 

ill check em out, but both at the same time arent lockin in? that would be a incredible if both stopped at same time..

 

not free sppining, but thier moving back and forth with the with the drive shaft bein moved

 

How long since you used 4WD and you know it was working?
Maintenance since then?
Something isn't adding up.

Oh well thats normal. That will happen regardless of whether the hubs are locked or not, and if its in 2wd or 4wd.

Put the entire truck on jack stands ( or remove the rear driveshaft and put the front on stands), lock the hubs, put it in 4wd, put it in gear and see if the front driveline is spinning....

 

was workin fine before i had it down to rebuild motor, was plannin to change the oil in it this weeknd, thinkin ill hold off for now

 

ill throw her up on jack stands later today, ill check in with results later today
