Did I damage the diffs?

2016 cascadia. I forgot to shut off the diff switch 1100 miles ago. I know it disengages after a certain speed. But thats all I know.

 

No you didn't. Way up north its common to have the power divider engaged all winter.

 

There is not a light, or a buzzer/beeper, that activates when you engage?

 

There is a light. But it's behind the qual com.
I was distracted by something ive never had to deal with before and it took all my attention. I did everything right. Other than forgetting to flip that switch back.
Face palm.

 

It can destroy them. If you turn a lot on clean dry pavement that causes damage. If your going straight down the road, there isn't much difference between tire rotation on either side of the axle, then it damage them slower. I have been told they will get loud and sound like grinding, if you hurt them.

 

Ok cool none of that, atlease at this time.

 

You could check the fill plug on the top. Put your finger and see if you have metal shavings. The plug is usually magnetic, at least the bottom one is, and shavings stick to it. They normally have some shavings in there any way after a couple 100k. I probably wouldn't worry about it, but I might dump the fluid in a couple in of weeks or a month. If the fluid has been in there for a year plus.

 

I will get on the fluid. Change soon I didn't know that was a thing.

 

I usually do it every 250k. I think you can got 400 or 500k.

I had a wheel seal go. They didn't tighten the hub nuts when they replaced the seal. So the hub was super hot, pumpkin was hot. Heavy oil dripping out, I didn't lose much oil. I tightened it down drove 400 miles and got it dumped. I was on long island when it got loose. Sapp brothers on 80 in Pa. It was $200 for one pumpkin, $400 for both and transmission. So I got them all changed. Probably more now fuel is 70% more now.

Anyway good luck. You probably didn't do much to it, unless you were driving 1100 miles local in Chicago or NYC.

 

Shut off the switch and resume life as normal. You didn't hurt **** and you wouldn't hurt ship for a very long time. Don't change the fluid or do any hocus pocus your fine
