I have a 2004 Jeep Wrangler with a 4.0. So the best way I can describe it is that when you’re driving and let off the gas the Jeep will kind of kick sometimes it’s soft and sometimes it’s a really hard kick and sometimes it won’t do it all. Any ideas? I also am having a problem that when I turn or go over a bump slowly you can hear the front end pop and sometimes you can fill. Any ideas on what either problem would be would be greatly appreciated!
