4WD feels a bit rough
I used 4WD the other day for the first time because everything was glare ice. I was slipping trying to get out of my driveway and decided to put it in 4WD. When it was in 4WD, I tried to backup again and BOOM!!! It engaged violently, but got me out of there. My wife thought we got hit by a car. I used 4WD a few times since then during some wet snow and have not experienced the violent engagement.
The 4WD does seem jerky. Would worn u-joints cause this? I'm not even sure what model transfer case these trucks have. Are they all gears or do they have a chain in them?

I assume you have the shift on the fly system. Sounds like you started to spin before the 4wd was engaged. On the ESOF systems, sometimes the vehicle needs to move a little before everything lines up and engages. The vacuum style hubs also need several seconds to complete the lock sequence.
Which truck did this happen on? What 4wd system do you have?

ok, on the ford hubs i assume you have a ttb 44, i ran into the same problem, have you serviced your hubs recently? if they are set up wrong or have to much grease in them they will slip and give you a nice boom and a jolt. this can also happen if a hup slips into the free space between locked and free.

I had that same issue with my Blazer, turns out someone had packed the locking hubs nearly solid full of what I was told was wheel bearing grease. It is my understanding that there is supposed to be very little grease there, and that it is good to use synthetic grease instead of regular grease because it does not get sticky when it gets cold outside?

Sounds like a quick job now. Will spray-on white lithium grease work? I've got a can of it in the garage.

I have never used the spray on type on the hubs, but I don't see why it wouldn't work. I have a 2 lb. tub that I use. I have also got it in the squeeze bottle,which works good to install in the hubs.

I haven't had a chance to address the grease still. I notice there seems to be significantly more resistance when in 4WD than when not in 4WD. I can let off the brake pedal at a stop light and it won't move. If it was in 2WD, it would roll free. What would cause this? Are my lockouts just be worn out?
