Did you drive in 4wd on the pavement, it will pop and grind.

I was on hard dirt about to cross a pipeline trench that had a spot where dirt filled the trench so I could cross.

Then yes sounds like they are bad. Look at the boots on them and see if the grease is coming out-thats a big sign they are toast.

Yea there is a little bit of grease left in them. I want to just replace them since I have new ones but I just dont know how.

get 2 floor jacks
one goes under the opposite side rear axle of the cv you are changing.
one goes under the a arm the closest you can get it to the outside of the truck...
unbolt end of axle from hub..
unbolt 6 bolts on diff side of cv..
then you can wiggle slide it out.. i didnt need to undo anything eles and changed the cv in about an hour first time.. it was passenger side

How do you change CV angles? Cake, you just crank em torsion bars. You did say change em for worse right?

I need to change the axles not the angles.

when you're in 4x4, you hear a popping and a deep rumble that sounds like its coming from the front, huh? yeah, CV would be my guess. mine do the same thing, as soon as i get the money to replace em, i am. but how sure r u that your hubs are ok?

the bolt & the c-clip on the axle end (might not be a bolt,some don't have it) & the bolts around the axle flange (under the truck). The rest is holding your mouth right while you wiggle & cuss & try to line them up with the cut out's on the flange & wiggle some more.

Personally I just popped out the studs with a c-clamp & ground off the splines, now my cv replacement only takes a few minutes for both sides to be done; still a pita but not nearly as bad as before.

Yea the popping and rumbles comes from when I turn in 4x4. Sometimes it even pops and rumbles when the wheel is all the way to the right or left in 2 wheel drive. I have 2 new cv's to put in and I'm gonna give it a shot today hopefully.

I got the new axles in and it turns smooth in 2 and 4 wheel drive. Thank you guys for your help.
