when i put my truck in 4wd it makes like a grinding/popping noise. the front wheels will spin a little then stop and spin some more, does anyone know what this might be

 

Wow man! This sounds like you have a different gear ratio in the front than in the back. But I dont know. lol

 

nah it's all the same gear ratio i had it for about 3years before it started making that noise and doin that the last time i really needed 4wd the front wheels didnt spin at all but the 4wd light in the dash came on needless to say i spent about 4hours digging with a shovel that day haha

 

Sounds like you have a blown diff or a broken CV.

 

yeah the cv boot did come off and the bearings started falling out last week so i know i do need a cv axle but when the bearing did come while i was driving it did make that same noise, i would have never thought about that might be making a noise, thanks man

 

sounds like your transfercase shift motor isnt engaging all the way, with your truck up on jackstands in 4x4, can you narrow down the source of the noise?

 

my cv axle messed up the other week so i went ahead and took it all the out and today i put it in 4wheel drive and held down the brake and gave it a little bit of gas and it went forward but it didnt make that noise anymore so i'm guessing it was the an pass side cv axle making that noise

 

Have you ever heard a Honda or other FWD car clicking while it turns? Dry CV joints which are on their way out. Same thing can happen to live axle Rangers.

 

nah i've never heard that noise on any other cars or trucks i'm pretty dumb when it comes too working on trucks, so i didnt know it was the cv axle i thought it was the tcase screwed up, thanks to everyone who helped me out on this

 

You have IFS. That is the only way to get power to the wheels with an IFS. Good luck man.
