WTH (Heck) Please help

[No Pvmt]

My kids said "Let's drive in the creek it will be fun" they said.....

Please help my D2 (`04) will ONLY drive in "Locked Mode." Everything looks ordinary under the truck (TC), what could I have done? I did hear a clunk sound that I attributed to a branch I drove over. How long can I drive in locked mode and is it going to mess other things up? My wifes going to flip because I just dropped a fortune on having the engine rebuilt three weeks ago....

Thank you for your help!

No, do NOT drive in locked on the road. Did you feel the linkage from under the truck? I know you said you looked but did you check the linkage?

What do you exactly when you say it only drives in Locked mode? Like you can't get the lever to disengage? The lever moves but nothing happens? ect? We need a little more, you didn't really tell us much. The more specific you can get about what you felt when it happened anything there after, every little bit helps.

If one of your driveshafts isn't flopping around under the truck you probably broke a diff or axle shaft.
Be thankful you have a Diff Lock or you'd be going nowhere at all.


Is it possible you just didn't shift the Diff Lock(or its stuck) all the way into unlocked? There is a Neutral position.

Thank you for the quick responds.

I can place it in gear as well as move in and out of lock Hi and Lo. When it's in normal drive it just revs, I don't see anything hanging down or lights flashing infact it beeps when it goes in and out of mode. My back tire are the ones that seem to only be working.

Sometimes you have to reverse for a short distance to unlock.

 

[fishEH]

Sounds like you broke something up front then. Either diff or axleshaft probably. All the power is going to the front end which is broken. When you lock the center diff it applies 50% of the power to the back and you can move.

 

[fishEH]

Have your wife sit in the drivers seat. You look under the truck. Unlock the CDL and place the truck in Drive. Look for the spinning driveshaft, that will tell you if the front or rear is broken.


*Don't get your head squashed under a tire, though.

 

[No Pvmt]

Great idea she just pulled in... damn

 

[No Pvmt]

Okay, the front drive just spins and the rear is not moving. When it was placed into park it sounded like a pin spinning against something, when I placed it in park in locked mode I don't hear anything out of the norm. It won't move in rvs or drv. When I was trying to climb uphill it was the rear that was turning.

So if the front spins something in the front is broken like the diff or front axle. drain some fluid from the front and see if you have part of your gears coming out with the fluid. If not pull the axles and see which one went snap.

How far can I drive in locked? I think the salvage yard has an `03 and it's 35 mins away.

Pull the front driveshaft out and drive it in locked.

Since your front is broken and not getting any power to the wheels, there really isn't anything wrong with driving around locked.

atriot: Thank you all for your help!

Unless more bits go boom in the diff or the axle starts to cause problems. In a DI you can do that if you pull the axles and the drive shaft. I would not risk it in a DII if you do not know what is broken, not 35 miles each way. If I am wrong someone can chime in.

 

[KyleT]

Ya wouldn't risk it in a d2.

You probably have a broken CV joint if I had to guess. You cannot drive with the axle removed as the axle holds the wheel bearing together. If you drove without the axle in place the hub would come apart. Jack up the front wheels and see if you can figure out which one is broken.

 

[No Pvmt]

Never thought about the CVs. Would it be possible to blow both out? It ran smooth on the way home, I didn't hear any grinding or popping.

 

[1MITCH1]

Only one needs to break to leave you stranded.

If one broke it would have a similar effect of that wheel being on ice. The differential will transfer the power to the wheel with the least traction.
