2019 Freightliner Day Cab Diff Lock

i have never seen an axle with diff lock inside...

 

men this is real 4WD truck.... good for offroading )))))

 

Lot of owner operators spec trucks with full lockers.

 

A truck without full lockers is useless around here.

 

It’s been 5 years since I sold my 2015 T680 but I think I had something like that.
One switch was for the power divider.
The other switch disabled the traction control. But you had to hold the switch up or maybe down to temporarily disable it.
I’m not sure what I had for lunch, so don’t hold me to my memory from 5 years ago.

 

These trucks run Houston to Edmonton and Alaska all the time,you need to lock everything up sometimes,either get yourself unstuck or dig in deeper.With these don't ever hit a diff lock if you're spinning,or drive with everything locked on the highway,it will overpower the steering.On older trucks hauling gravel in belly dumps we would lock in the interaxle and rear diff,almost never get stuck dumping.

 

These trucks would be ok with more hp.
