when under power or turning sharply in 4wd my jeep makes a continuous popping sound. in 2wd there is no noise. anybody had this before? is it the chain?
The quadra trac is installed on Jeeps with continuous four wheel drive and cannot be disengaged to two week drive.
I would suggest that the front U-joints many be failing and unloaded they make little to no noise.
Other possibility are the front U- joints on the drive shaft which again are unloaded in two wheel drive.
Good Luck
