No, but lets just say he was more than a little pissed.

Definitely check the axle with trans in park. If it's an open, the carrier will stay put and the spiders will make the tires spin opposite direction. If it has any traction device, the carrier will stay put and the torque management system will keep the axleshafts engaged to the carrier, which means nothing will move.

See if you can pinpoint the noise source. Maybe have somebody get out when it makes noise while stopped. Or you get out. Maybe it goes away in park/neutral? I can tell you my trans makes a racket in neutral, but park is fine. I think it's just a shave out of adjustment.

 

Just freaking bizzaro. I don't know if it's loud enough to capture on video or not..... May try it. IF I can find the time.

That's why I didn't do the gear oil change myself....that and the $20 Off coupon at the shop.

 

10-4. Hopefully, I can get to it tomorrow.

 

Ok, just got back in after jacking the rear end/rear tires off the ground.

Transmission in Park. Could not in anyway, shape or form turn either rear wheel by hand. Natta.

Transmission in Neutral. Turning either wheel by hand made the other wheel turn in the SAME direction. No hint of a wheel attempt to turn in the opposite direction.

Conclusion ??

I know it's a Chrysler 8.25". Is it made for Chrysler by Dana Corp ? If so, which Dana model is it ?

 

no, chrysler 8.25 is the actual axle name.

Sounds like you definitely have a LSD then. Dodge does not use dana axles until you get to the ram 2500. The dakotas use the 8.25 and 9.25, ram 1500 uses the 9.25

 

Unless there is a problem with the spider gears that is preventing them from moving freely. In that case both wheels will move in the same direction.

I know I've said it before, pull the cover.

 

The older D2500's- the newer ones (since '09 for sure) use AAM axles.

Pull the cover and take a pic.

Only way to know for sure.

I have had the center pin break, and make it act like a locked diff.

A broken tooth from any of the gears could be wedged in the spiders.

Very possible someone made a 'Lincoln Locker'* out of it prior to you getting it.

*(Welded the spiders to the side gears)

Most older LSD's are worn out, and will not lock up as solid as yours seems to be.

If it is an LSD, the clutch pak may have disinegrated, causing problems.

Only way to tell is to pull the cover and inspect it.

 

Ok. Thanks

 

Roger that.

I will visually inspect it soon. First of all, I want the shop to redo the job and refill in using Friction Modifier.

If they claim it is an OPEN rear end then I seriously doubt they added ANY Friction Modifier. That "could" be part of this whole problem. ??

I will stay and visually inspect it for myself and yes, I most definitely will take/post up pics.

 

Roger that. Good points as well.

Will post pics ASAP.
