I have a 8 cylinder 7.4L suburban. A friend had vehicle in drive but not moving and engaged 4wd. What kinds of problems could result from doing this? The shop said I needed rear axle housing 3/4 ton w/9.5" ring gear, transmission, and a transfer case to be replaced with used parts. I am wondering what could have occurred by just pressing the 4wd button while the vehicle was not moving but in drive. Please let me know if this sounds right.

It'll probably be fix when they replace the transfer and transmission-

Is it possible to cause those types of damage just by attempting to engage 4wd while in drive at a standstill?

Could be a problem with the transfer case switch

Would the transfer case switch being bad cause damages to the rear axle housing ring gear and transmission?

No it won't, just for the 2wd/4wd engagement
