Center Diff Lock while in Reverse

[Weave]

So last week I'm in reverse with a trailer and reach down to extinguish the back-up warning alarm, but unwittingly hit the center diff lock instead. This is followed by a loud "BANG", and I thought I had hit another car.

After confirming that I had not hit anything, I drive away and immediately notice a significant change in handling, along with an illuminated diff light (my first indication that I had hit the wrong switch). I disengage the lock, and it resumes normal operations after driving forward approximately 150 yards.

However...since that incident I notices a slight vibration through the accelerator, along with a small cavitation when driving at highway speeds. It does not impact overall performance, but it's not the same as before.

I'm a bit hesitant to perform diagnostics, so I'm curious if anyone is familiar with this situation. If engaging the diff lock while in reverse can damage the drivetrain, I'm a bit surprised that some sort of override does not exist. In any case, any comments & suggestions on next steps would be appreciated.

Center diff lock while in reverse should be fine... Center diff lock while on dry pavement and not backing up in a straight line??? Not so good.

No, have never heard of anything like that before and I've been reading here a long time. Also, I've used the diff lock so many times under so many circumstances, I've experienced plenty of loud bang moments with no issues. The transfer case is very robust. Give it a little time to let your heightened senses get back to normal. I'd guess it's all good.

I think JB is right on and you're noticing somthing that was there before but due to the 'bang' you're noticing it as something new. I find it hard to believe you did any harm though.
