2004 Cadillac Escalade Ext V8 All Wheel Drive Automatic 70000 miles
My battery recently died. After jump starting the truck the tachometer stopped working properly and the truck rides like the front wheels are engaged in four wheel drive and there is a whining from the fron. They both started at the same time which makes me believe I roasted something, but what. I checked all fuses and found nothing blown. Is there something I could check/test or do I have to go back to the dealer? Please help!

As far as the whining and front axle issues, you could have bearings failing in the front axle. It is just a matter of how far gone they are. I have seen minor scoring, and I have seen complete seizure. You can pull the front axle drain plug and check for metal, but first pull the fill plug and check that it was(is) at the proper level. You will get metal on the drain plug magnet, it is just a matter of how much. If it is exhibiting a condition known as 'crow hop', when you are turning the wheel and it feeds back through the steering wheel and scrubs tires, you could also have a condition in the transfer case that is causing it to drive the front/rear at same speeds.

I will take my truck in for the gauge cluster. Thank you for the information. I dont, however, think the bearings would just go all of a sudden like that. It usually has some signs first. One day it was fine, next day, whining! Is it possible the tach is the cause of that too? I figured maybe the computer is screwing it up by leaving the four wheel engaged. Make sense? Again, thank you for the help!

There are no computer influences on your transfer case, or axle. It is a single speed, 60/40 split, all wheel drive system. If it is whining with vehicle speed, something has happened mechanically.
