I just recently bought a 99 4.7L 8cyl.Quadra-Drive Jeep Grand Cherokee that just rolled over 200060 miles. In the morning the oil pressure gauge comes on along with the air bag & low coolant.. I'm posting because there is a horrible popping noise and we're not sure what's the cause, we've replaced one cv axle joint on the front driver's side it stopped the noise for a little while but then came back, just kinda hoping I'm not the only person who's had this issue and someone might be able to help me before I start throwing money into it I don't want purchase unnecessary items if possible. Thank you for reading my post and all opinions & help is appreciated
