Has anyone experienced a popping noise from front axle during 4x4?
I took my truck offroading for the first time this past weekend. It is also the first time I engaged my 4 wheel drive. There were a few pops from the front axle. It felt like maybe the front axle slipped and popped back into place. I was in soft dirt at about 10 mph and it only did it a few times. It popped twice when I first engaged 4x4. Then later during a sharp turn. And again going down a steep hill. So, it did it about 5 or 6 times within an hour of offroading. What would cause this? Is this because it was the first time engaging 4 wheel drive? Thanks for any advice.

Another thing is that your truck is probably going on 3 years old and you've never engaged the 4wd. It's always a good idea to engage it every couple weeks just to keep eveything lubricated.
Look for tears in the cv boots on the front axleshafts. If the grease has leaked out then the axle is pretty much ruined. A bad cv joint will making popping noises that will progressively get worse as time goes on. If that is your problem, it's a pretty easy fix and shouldn't cost more than $75 or $80.

My understanding is the hubs are vacuum actuated. There are vacuum lines running into the hub for this purpose. The when you engage the transfer case a vacuum signal locks the hubs. I could be mistaken, but believe this to be correct. At least on the new body style 04 (not the classic, not sure what those have).
The driveshaft may rotate due to gear lube pushing it.
I have a Jeep YJ with a central axle disconnect - on that style system, one axle shaft disconnects, so 1 axle and the driveshaft are always driven... stupid set up.

The popping only happened on the drivers side. It happened mostly when I was turning. No popping when I was going straight up hill. I'm thinking maybe the accuator on the left side isn't fully engaging. Could this be the reason? It sounds like the popping came from the left cv not the transfer case. My cv angles are the same as factory, and the boots are perfect. I only have 17,000 miles on my truck and only 5,000 with my lift. Also, I was told to never engage my 4 wheel drive on the pavement. I live in Los Angeles, so it is difficult for me to engage my 4 wheel drive as often as I should. Thanks.

I may be wrong because all I have experience with are 97-03s, but I'm pretty sure the system works the same. On my truck, ther are no vaccuum lines going to the hub. The only lines going there are the brake line and the wires to the ABS sensor. I've replaced both my axleshaft and hub, and there is no way they can spin separately from eachother. The axleshafts spin whether the truck is in 2wd or 4wd.
