Engaged off-road at 45mph

[rockytj]

Did some searching and didn’t see any topics on this so hoping it’s not a duplicate.

I was driving and was changing from Normal to Sport mode, and accidentally bumped the off road option before switching to Sport. I was probably going about 45 mph, didn’t notice any changes in the drivetrain but know that the automatic engagement/disengagement of the diff happens at much lower speeds when the diff is locked.

Anything I should be worried about or watch for? Again I was going straight and quickly switched out but was just concerned as I was at speeds much higher than the normal limits for the locking diff.

Thanks all

I wouldn’t worry about it. The truck will protect itself.

If you were going straight I see no problem, just switch off the lock or get to another drive mode before making turns on solid pavement, all you might notice is a bit of tire chirp if the lock stay's on.

It was brief and when I was going in a straight line, so I think we’re good. Honestly I changed it so quickly it might not have engaged.

If memory serves me, entering off-road mode doesn't engage the rear diff lock.
You always have to explicitly turn it on regardless of drive mode.

How's the saying go? Ford wimpy? Ford soft? Ford namby-pamby?

NO! FORD TOUGH!

Correct. It was never turned on in this case. And, since OP was going straight, it would have caused no harm.

Edit - I was confusing my 2013 F-150 that I had for 10 years with the Lightning. Correct, the Lightning locker is automatically turned on in Off-Road mode.

My diff lock turns on when I enter off-road mode. I haven't tried to switch to off-road while driving, only from a stop. Either way, I would think off-road mode wouldn't engage above a certain speed, and if it did, the diff lock wouldn't engage immediately.

Note to self; no high-speed off-road getaways on extremely loose surfaces.
