I have a 2007 Silverado with the same problem. The "rear locking differential
" should automatically engage whenever one of the rear wheels spins considerably faster than the other. When the lock activates, the two rear wheels are locked together like an ATV.
What is wrong here is that as soon as this mechanism detects that the load on the two axles is back to normal, it should automatically disengage, but it does not.
That is the problem. The "rear locking differential
" does not disengage when back to normal. This can damage the rear differential or break one of the axles is the truck is sufficiently loaded.
It can also make you lose control of your truck by causing its rear to skid. This can be very dangerous
if you are taking a curve at high speed and the pavement is wet (like in the highway). The failure of "rear locking differential
" to disengage will cause one of the rear tires to lose its grip on the road loading all the centrifugal force on the other tire.
I still have to take my truck to the dealer to "try" to get this fixed, but I can see their answer already: "Your truck is within factory parameters".
Well, at least I want to set some precedent in case the worse happens.
If you took your truck to the dealer, could you let me know how it went?
