My '05 3.0 is now a rear wheel drive.

[X5goldie]

I totally lost the front drive. The last thing I did was replaced both front CV axles and found out later when it snowed that I don't have AWD. I bought the Axles from Napa auto parts and everything installed fine. I do however, get a clicking/ticking noise when turning the wheel, say getting in and out of parking. My question is, could it be that I installed the wrong/incorrect axles? could either axle be short? (unlikely)

I checked the transfer case actuator gear so see if it's bad although I am or was getting the 4X4, ABS signs flashing at the time I noticed losing the front drive.

The history on this car is it towed small trailer for some time.

Could it be a bad transfer case? Anyone having this issue? thoughts?

Thank you for any input you can provide.
