TheBlueWave said:In the 4th gen (automatic locking hubs) the truck has to be moving to engage 4wd. Make sure you are in 4wd high first, then shift to neutral, and apply the brakes (or make sure the vehicle is stopped), then switch to 4 lo. It should only take a few seconds to engage.
Falls said:The 4R does not have auto locking hubs on either the v6 or v8. They are always connected and turn with the wheels ( half shafts ) and the front drive shaft. The T case selector only engages or disengages the transfer case .
Either vehicle (v6 or v8) needs to be stopped and put in neutral , then switched to 4lo. Same procedure to disengage.
Methodical said:The T-Case selector engages the front driveshaft of the transfer case, and also engages the half-shafts to the front differential. The hubs are permanently locked and the front halfshafts always rotate, but they are NOT connected to the differential unless in 4h.

MrTom said:Once you register and sign in go to the "My Owners Manual" section . In the "search" block choose "owners manual" and put in a word or phrase for what you are looking for. It is configured for the vehicle you register. After a while you can see the format that brings up the various chapters of the manual in Adobe PDF format. I downloaded all the chapters and pieced them together with some shareware software. Just takes a little time and forethought..
TheBlueWave said:So if the hubs are permanently locked, why does the vehicle have to be moving to engage 4wd? Instead of locking the hubs, it connects the half shafts? Weird. I just learned something new on here again!
