Topic: Question on 4WD not working all the time

[Plowking]

Hey guys. Quick question. I was out in the woods recently and lost the front axle it quit pulling only seemed like it quit working in 4 LOW Could this be the front detroit true trac acting up? or the transfer case. I am running detroit true trac w 4.88s stock V6 chain transfer case on the axle in question. As I said the truck pulls in 4 h but front rear seemed to quit in 4 L
Thanks
Joe

i would imagine its something in the front axle... do you have stock birfields? you may have cracked or broke one


i would take the front axle apart and get to the bottom of it

[Plowking [OP]]

Nothing to suggest that. I had a hub problem at one time where one wouldnt engage but it was due to tire pressure differences and a hang up in the hub. The thing that got me was 20 mins before I got stuck in crick without 4WD I had crawled up a pretty serious hill.
Berfs redone 2 years ago.

   jack the truck up  4 jack stands   put her in 4l / 4h   and see whats turning    if the front shaft turns but not the tires its in the axle or hubs  and vise versa.

[toyotanner]

well if you dont think its the axle then its the tcase really only 2 options here haha

[Plowking [OP]]

Why would the back tires pull and the front ones not dosent make any sense for it to be the transfer case.

[toyotanner]

so your saying its the axle haha... just do what unclej said to determine where the problem lies....

still IFS??   do you have ADD??  possible one of the vacuum hoses got pulled off

my suburban has 4wd in 4hi but only 2wd in low range,

I bet the add actuator is toast. I cant remember what said it is but hook a vacuum line up to one of them until it locks up. THen just get manual hubs

How in the heck could NOT KNOW whether it's the transfer case or not??
It's as simple as sticking your head out the door and LOOKING at the front drive line - does it move or not???

If it's moving, then I would go straight for the locking hubs.  Pull them apart.

[Plowking [OP]]

I dont use the truck alot. I am hoping it is a hub. Have yet to tackle it. Will let you know

[unclejpl4x4]
