Hey guys as usual I got the 2 common problems of the envoy. The first is the dreaded air bag leak. Originally my truck would only hit the bump stops every other week then it went to every night it was cold then every night now every couple hours. I know there are a couple options but I want to get some opinions. The first is I guess there are two options for air bags from arnott I think it is. How do these stand up over time and quality wise? My next question is if I go with the springs do I need to get mounts for the top or do they just slide Ito place of the coils and that's it. My next major problem is my rear end. The g 80 is cooked and locked solid. I do not care so much now but in the winter months this will get pretty dangerous and it drags around corners and makes the vehicle jerk and chatter. So I know there is a true trac or I have found and axle out. 2006 tb ext it is going to cost about the same either way which do you think is a better option this is just a daily driver not trail rig or real heavy tow rig
