Rear Diff getting replaced at 14.5k

'24 with 14,500 miles. So today I was leaving a stop and the vsc, abs, blah blah, warning lights came up. I was due for 15k anyway so I scheduled and went in. On the way I noticed the rear diff red symbol in upper right was flashing. The other warnings were randomly turning on and off. Ends up I need to leave it with them Monday to dig into it. I watched a couple vids and appears to me it's a switch malfuction. Tech said he had seen before the rear diff was full of goo from the factory causing such a thing. It's not locked in for sure and light is just flashing causing the others to cycle on and off. We shall see what happens Monday. No loaner until they determine the cause of course.

Oh, it all happened just after I had one of those poo your pants hesitations trying to cross traffic. That was supposedly fixed the last time as well.

 

Dealer just called. Truck is getting a new rear differential. Metal came out when they were doing a fluid exchange. Claims my throttle hesitations are due to it locking up everytime I leave from a stop. Maybe just a reasonable guess since the diff is f'd but don't think everyone with the hesitation has rear diffs locking up. Better than a motor I guess but time will tell on that as well. Getting loaner truck for the week.

 

Interesting…

Bummer to hear about the issue but glad they are taking care of it. I had no idea there was a rear differential monitoring system of some sort and a dash light.

 

So, just a regular Tuesday?

 

I'm thinking OP means a diff lock indicator light

 

That would make more sense.

 

no kidding. I got a '24 SR5 for a loaner and I swear it is a ton more responsive on the throttle than my truck. All I can do is wait to get mine back and see if that's the case.

 

If they are going to have it for a day...
FYI.

 

He mentioned he was getting a loaner.

 

Thanks man,I kinda missed this thread from the start,and after I had posted it I had then realized I was a little late to the party

 

My diff has been replaced 3x by local dealer within 12k miles. It started with a noticeable howl / whine between 40-50mph and again at ~80mph, when foot is on the gas, take foot off the gas it stops. I am unloading the truck at this point.
