Differential flushing???

[Wowowee]

So I went for routine oil change my dealership,, I know was due for diff oil change and may be transfer case as well.
62,000kms. I know it’s an drain n fill, service rep says it has to be flushed, never heard of this procedure, ask em how it’s done, he says we run another oil thru it then flush it.. is this true? Says if I do it myself and problem arises it can void my warranty.
Any thoughts?
Thanks in advance?

Hopefully they will change the blinker fluid at the same time…transmission fluid flush maybe, not the differential however.

I've personally never heard of a flush. I think they're trying to scare you into paying extra by deterring you to do it yourself. Draining and filling is one of the easiest maintenance you can do on the Jeep.
