Can a non working four wheel drive affect the rest of the vehicle
I have a 2000 Yukon Denali and the four wheel drive does not work at all. Can that have
an impact on the transmission or engine even if I don't use the four wheel drive?
Engine or tranny won't be bothered by a nonfunctional 4X4 however the front differential may start to have problems if the unit is not engaged from time to time. I am assuming that the transfer case has the problem and not the front differential.
