Trying to determine if this is normal for a 4wd or if I have an issue.
Yukon AT4. 6.2L. 2023. 18K miles.
Frequently I park in front of my house pulled up next to the sidewalk. Because of how I leave the neighborhood one of the first things I do when i start up the truck is to initiate a left K-Turn almost immediately (I might roll forward a few feet or back a few feet (if my daughter has once again parked in front of me too closely)). When making this turn, after i've pulled across and backed up and now pulling forward again, making the top part of the "K", there is a sizeable thump/slip/jolt that occurs. It occurs twice. Almost as if it's the front wheels and then the rear wheels doing this. It almost feels like i've run over a tennis ball (twice).
it's not tire related. They are relatively new and have been consistently rotated and are inflated properly.
I've checked many times to ensure that I have the trans selector on 2WD and Normal drive mode.
I've also put the vehicle into 4WD and driven a tenth of a mile to make sure it engaged and then back to 2WD and drove another tenth of a mile to make sure 4WD disengaged, and I still got this same thump next time I did that turn.
I have noticed that if I roll down the street for 30-40 feet BEFORE i do the K Turn i get this much less frequently. I did this test as i wondered if this was somehow related to the drive train needing to "engage" before putting it through the turn. Preliminary research has suggested this could be a number of things that seem far more common with older vehicles. This AT4 is 2 years old and has less than 20K miles and has never done anything that could have damaged any control arms or bushings or things of that nature.
Is this just normal for a 4wd making a low speed turn right after starting without having driven forward for a bit?
