Blackedout07 please keep us updated on this issue.
I just changed my front left CV axle today because of the same problem.
Mines an 04 with 112k and last winter it started popping in 4wd only, i thought for sure it was the axle, cause it seems to pop most when turning right,left, and turning in reverse etc.
I checked the teeth/splines on the axle,actuator,hub and they all look brand new, and full of grease.
I put a vacuum gauge to the vacuum hose going to the iwe and its holding steady at 20psi, does anybody know what psi should read????
I the only problem i found with the IWE was one of the bolts that hold it on was already stripped,was any of yours stripped?
The beginning of spring i replaced the fluid in the front diff,it had some water mixed in there, I'm assuming from the snow cause the vent tube was pulled out, so i put fresh fluid in and checked all the gears and mine seemed fine, no binding or anything.
So i can only come to the conclusion that the IWE has to be at fault, cause i don't see a wheel bearing making a popping noise.
But i could be wrong, and if i find out the problem I'll report back.
