I removed a hub to replace my CV shaft, one of the boots was cut. After I was done and had replaced the hub I no longer have front drive in 4X4. I think it may be something to do with the hub clocking...any ideas? I have autolocking hubs. Thanks

 

Yep, sounds like a hub problem - the open diff won't transfer power if one of the hubs is unlocked (all the "power" will go to the unlocked side).

 

take it off and check the order of installation, there could be a seating ring in the wrong location not allowing the spring to engage the internals.

Thanks leebee
I know the hub has to go on a certain way...but I can't figure how .
I'll have another look at the spring.

 

here is a link to the fsm i use:

http://personal.utulsa.edu/~nathan-b...fsm/index.html

look in the suspension and axle section, there is a detailed write-up for your manual locking hubs.

hope this helps.

Just make sure everthing is installed in the right order. I just replaced might left cv axle with auto hubs and the 4x4 works.

 

Thanks again! After I read your first reply it dawned on me that I should check the FSM

 

huntnfreak,
Care to stop by and give me a hand...I'm probably only a couple of thousand miles away. You have described just what happened. I changed my left CV with auto hubs but the 4X4 will not work.
I'm going thru the FSM with an eye on the spring. I think/thought I put everything back in order but obviously something is not right with my thinker. Thanks again everyone I owe you each a

 

Ok I've studied the FSM and I now have the hub body off the end of the CV. I haven't disassembled the hub and everything is moving around real well. So I'm going to rule out the spring for now. I'm still thinking it has something to do with the clocking/orientation of the hub body to where it mounts.

Can anyone give me additional information on this problem? Thanks in advance!

 

Transfer case problems?

 

i agree with the clocking suspicion but dont no the right way so im sure someone else will chime in, or you could read in to the fsm a little more..

 

I have manual hubs, so I'm not real familiar with how yours works.
I had the same problem when I bought my truck. I toyed around
with different things for a while. Long story short, during a recent front
brake job done by the PO, a gear was intalled backwards when reinstalling
the driver side hub assembly, causing it not to engage fully.

 

Well, I read and reread the FSM and put it all back together....still no front drive when in 4hi or 4lo. Any more ideas or suggestions are appreciated.

 

Do you have ADD on your front axle?

 

I have auto hubs not ADD.

 

NOW WERE TALKING I'll bet you're right on the money! I remember looking at it thinking something's not right there. I'm gonna start looking for those springs. Thanks again!
