Any body no what damage can result from the inter axle lock out being ingaged for prolonged amount of time with high speeds driven.
Basically I engaged it to help get out of a hell hole down by the lake where my customer moved into. The red light was burned out so I forgot to disengage it and drove mucho miles at highway speed before i noticed it.

When the differential is locked, the rigid connection between the rear wheels has a rubbing effect on the tire when cornering. This leads to increased tire wear and also to "jerking motion" when the vehicle is being steered.

Basically what a differential lock does is make all the wheels power at the same speed, while when it is not locked, only one side is powering the unit. When you are going around corners or curves, the side that is traveling farther will tend to want to rub or slide, as it will want to go the same speed as the side that is traveling shorter.

There's a difference between a Inter-axle Lock and a Differential Lock.

Inter-axle Lock (power divider) = Locks both drive axles together so both of them provide additional traction in adverse conditions like mud, snow, sand.

Differential Lock (cross lock) = Locks both sides of each axle together. Unless specifically ordered, trucks come with 'open differentials'. This means that the set of wheels with the LEAST amount of traction gets the power. 'Limited slip or locking differentials' have clutch packs in the ring gear carrier inside the axle housing. Any slippage of one side makes the clutch pack lock up and provide power to the other side of the axle.

Unless you were doing a lot of stop & go driving with the inter-axle lock engaged, it should be ok.

One time I hit about 500 miles of slick roads and locked mine in and rolled the entire distance before unlocking them. Never noticed any harm done to the power divider.

You're both right.

Running with the power divider(interaxle lock) engaged will cause no harm.Extended running like this could cause increased tire wear but nothing else.

Peew thanks guys. I was not sure if i could have damaged something inside one of the pumpkins or not. Of course now it seems like i have loud noises coming from that area and the shifter seems to be ratling more than ever. I guess if your listening for a problem to happen your gonna hear something.

Check the ride height on the air suspension on your drive axles- if it's out of adjustment (either too high, or too low), it will send some awful sounding noises to your cab through the driveline.
