Clunking/jerks while in 4x4
Evening everyone. Been a while. My issue is with my 2013 f150 5.0l 4x4 with 127k
Drove into work yesterday in 4x4 all hwy without issues. When I then slowed down to make a right turn and proceeded on mine road with a slight incline it started to clunk/jerk, ( like pretty hard and loud too)if I let off the gas it stopped and as soon I would hit the gas again it would clunk/jerk again. I switched back to 2x4 and all is good.
My first thought is transfer case? But I dunno. Any help would be greatly appreciated. tks again

you should not be driving in 4 x 4 unless the conditions are REAL BAD... If it jerks and bucks when you turn, the road is TOO HARD / not slippery.

Ok...finally got around to playing with this issue while close to home. Road conditions are completely snow packed. Stop...put it in 4x4 and accelerate moderately....between 20 and 40kph I get a "clunk" like gears engaging or something. Straight road no curves. It doesn't do this while in 2 wheel drive only in 4x4. Put in in 4 low....backup for a bit. Tranny is in neutral prior to shifting from 4high to low and vise versa. When back in 4high it still does it....one time I got the jerky clunk at 30 and at 40 so it hit twice. Feels like it's under my seat. Wife was also in the truck so I'm not crazy....I'm at a loss here. Any more ideas folks?

Sounds like your transfer case might have some issues with the gears. Also, I'm sure you know this already but you should never make full lock to lock turns while in 4WD. Might want to do a transfer case fluid inspection just to make triple sure that you don't have gears starting to strip.

Continue driving on HARD PACKED ROADS until you eventually tear it up..... DONT use 4 x 4 especially on corners.

Maybe check front driveline ujoints for play? A seized ujoint/cup could cause a clunk. The hubs not engaging would be a grinding not a clunk, so I think we can rule that out. Especially if you can feel it.

All this nonsense of not turning while in 4x4....pffft! You guys are too hard on him! OP, look at this a little differently: if you get slippery-er tires so they can slide in the turns your clunking should go away.

I'm not sure what the heck everyone is on about driving in corners in 4x4. What I said was I slowed down to make a right turn then proceeded down the mine road....is when I heard the noise. It was a snow storm and was not driving on pavement or asphalt. Sheesh. And tks guys I will check the front u joint and drive shaft
should the drive shaft be tight or is there some play in it ?
