Had new tires put on my vehicle listed above they did not do alignment tires wore on inside had two new tires put on but different tires not the same. Now service all wheel light is on and noise from front passenger side and backing turning feels like brakes dragging.

Hi,

The first thing to confirm is that the correct size tires were used. They must be the same size as the two you kept.

If they put two different size tires on the vehicle, that certainly will cause 4wd problems. Also, there is a chance that the wheel speed sensor may have been damaged or disconnected when the tires were removed and replaced. That will turn the light on for you.

I attached a pic below showing the wheel speed sensor's location behind the wheel. Check that wire I highlighted and make sure it is connected and not damaged.

Let me know what you find or if you have other questions.

Take care and God Bless,

Joe
