I have had this problem for a while (like a few years). When i have my truck in 4 wheel drive, i usually only notice it in 4low it makes a popping in the front end. It seems to do it every time i take off from a stop with the wheels turned or when switching from forward to reverse. everything still works fine it is just kind of annoying.

 

I believe it is from something binding up. But I could be wrong, but thats what it sounds like

 

i thought it said pooping. ha!

 

Thats what im thinking too but im not sure what it is. I didnt know if anybody else had this problem or had an idea what could be binding

 

just bhad the same problem with my truck, turned out to be the cv joint

 

how did you fix it? just replace the cv axle?

 

my dads 02 has done that since it was brand new the ford garage said its normal? beats me

 

mine started popping in 4wd, it did that for about 2yrs,finally the cv axle went out all together, went to advanced auto bought a new one for around 80

 

mine has been doing that exact same thing....and its weird cause it did it before i snapped my driver side cv, and after i replaced it..and a couple days ago i broke my driver side one again....i think this time i might do both of them...lol

 

wow mine does it too...I thought it was the superlift! Like it kinda "clunks", whenever i noticeably speed up or slow down in 4wd. I didn't know if the ABS was ****ing up or some weird bolt was loose. But it's noticeable and just feels like a part is shifting slightly when i speed up or slow down.

 

bump, i need confirmation that i prolly need to replace cv joints or some ****

 

these threads are floating around a lot.

 

My truck was and still is making a popping/clunking noise in 4wd mostly while turning. I can really feel it in the steering wheel. It seems to start when I'm turning tight and continues until I straighten the wheel out. Even then it doesn't let up sometimes.

When I re-did the front I got new cv's and still have that popping. Not sure what is going on. I'm not sure if I have the coilovers cranked too tall and they're over extending or they're binding up somehow. But I need the height clear my tires.

I know my situation is different but I would start with cv's and u-joints.

 

Mine has been popping for awhile too, mine will pop sometimes when turning in 2wd. I have spares but it hasn't broke yet

 

The binding is completely normal of a 4x4 truck operating in 4x4 on high traction surfaces. The only time you are supposed to use 4x4 is when you have limited traction situations. The binding occurs in the transfer case. The case locks the front to the rear there making them spin at the same rate. Now when you turn the steering wheel and attempt to make a turn on high traction ground, the wheels do not want to slip. The front tires turn a different rate than the rears do when you turn. The only thing left to make up for the different speeds is the transfer case/ cv joints in your guy's case. If it were snow or dirt, you probably wouldn't notice anything because in this case, the tires would slip.

 

Thats when i use 4 wheel drive is in the snow and "dirt" and it happens. im not going to start replacing parts because something is popping. my truck isnt a DD so if it breaks while im out messing around then ohh well

 

ya mine does it when im going slow and straight...i notice it a lot in the sand and when im really pushing the drivetrain going up hill climbs and stuff....i hate it tho...lol

 

does it feel like a chain is skipping on a sprocket??? i was reading on TRS and the ranger's are known for the chain in the transfer case to stretch and start skipping on the sprocket. if its more like a "clicking" sound when in 4wd and 2wd then its the automatic hubs.

my 93' clicked and skipped so bad even in 2wd that i couldnt get above 70km/hr and i just replaced the u-joint and the cv joint was fine, it ended up being the auto hubs were shot, took them off and everything was fine.

 

My truck does this too, it is my wheeler and my Dailey driver so I want to fix this problem as soon as I can. I have replaced my cv joints.Any one have any more tips?
