Rear end queston
Can you help me figure out was the size
gears in my truck diff ; its a tahoe 2000 5.3
round body style 4×4
I can narrow it down, either 3.73 or 3.55 to 1 ratio. There might be a tag on the rear end differential with some numbers, or it may be in the vin number, that you would have to check with the dealer with.
Take the VIN number to the dealership service department and ask them to look it up.
