So this has only happened maybe 10 times. And I have only noticed it when I am in my parking garage making a left turn. I hear a wheel being dragged. I will have that dragging sound from the rear till I get going straight again. Rear end is definitely locking up. Anyone else have this issue? Oh and truck only has 17,000 miles.

 

Some differentials require a special lubricant. If your vehicle has a posi-rear/ limited slip ,rear, it may need to have the special lube (with additive) checked and maybe some added.

 

are you in 4wd w hen this happens?

 

I don’t have 4wd. Went cheap when I bought it.

 

I've had this happen a couple times over the course of 70k miles on my Trailboss LT2. For me it seems to happen if I'm rolling up to stop sign and turning at the same time....seems to depend on what speed I'm slowing down from (i.e. what the transmission is trying to achieve)......just my observation

 

so they replaced my TCM. They told me it had a fault.
