Started having problems with my 02 CC. More specifically, in 4 lo when turning either directions, i would hear a popping ( like a baseball card on your bicycle spokes ) Took out of 4 lo and into 4 hi still same sounds. Tried 2 hi only and same thing.
It does it only when 35% or more power is applied and turning. When going stright, you can give it as much as you dare and no popping. It will still change into all 3 4x4 modes, but still not right. I am unsure it it is actually going into either 4hi or 4 lo. I am fearing it may be something in the transmission or transfer case. I am not that good with transmissions or T- cases. Fluids all good.
Wondering what i can look for to figure out what is wrong.
T-case?
Transmission?
Differentials?
Please guys send me in the right direction if at all possible.
Before this started happening, i was towing some water tanks ( 2- 275 gallon tanks on a tandem axle trailer { close to 4700 lbs}). I would use the 4 lo to hold back when descending a small hill. Later i started just riding the brakes and not going into 4 lo. Have not towed since this started or driven hardly at all.
If, this was me, I would start checking the front end components and not worry about the TC, Tranny or diff yet. Make sure the TBs and front end components are good.
