Here is a quick easy way to see which wheel is sticking. Jack the front end of the truck up. Start the engine and try to spin the front wheels by hand. If both are sticking check the brakes or the front wheel drive 4X4 assembly. I believe the hubs are vacuum assist to engage the 4WD. It's also possible the front hubs have seized.
I can try jack the front end again and see if I can spin these tires by hand. My driveway is kinda steep so I really don’t feel comfortable working on it. I did all 4 calipers on my driveway but man I was kinda scared of the Exp falling into my 2017 f-150. I can’t really park on the streets but I shouldn’t have taken any chances. I’ll park the f150 on my lawn if I have to.
Do the same for the rear but the truck will need to be in neutral. The rear wheels should spin freely. If they don't then check calipers and rear brake shoes. If those are OK then maybe the rear hubs are sticking.
I didn’t give the rear wheels a full rotation when doing the calipers but I did turn them a little back and forth by hand.
Have you ever removed the hubs and repacked them with grease? Is your SUV 4X4? The more info you can give us the more likely we can help narrow things down.
Nope, all that has been done to this truck in 6 years is the regular oil changes, coolant flush, spark plugs, a couple of coils brakes, rotors and recently all 4 calipers, rotors and pads all around. Truck is an 07 5.4l Eddie Bauer and yes it’s a 4x4 but we rarely use the 4x4. Most of the time is on 2WD.
One last one and this may sound silly but if your tires are at 20psi, they are less likely to roll than if they are at 35 psi. It's just a process of elimination.
Yes, wife is the primary driver and for some reason the tire pressure light comes on like every other week. We had new tires installed almost a year ago but I’m not sure if they replaced the valves. I’ve been meaning to take it back to town fair tire but haven’t had the time yet. I ended buying a compressor pretty much to fill up these tires instead of hunting down a working air pump at gas stations every time the tps light comes on.
