My qualifications to answer have only to do with the number of years that I've owned Jeeps and the fact that most of them have been slightly to very well used. I tend to keep vehicles for a long time and therefore have amassed a lot of information and all of the repair books for older model Jeep Grand Cherokees. I'll be quick to recommend that a person take a certain repair job to a professional if, in my opinion, its something that requires specialized tools or if a botched repair job in the driveway will cause potential death out on the road.
I've been a single parent for most of my son's (John and Christopher) lives have found parenthood to be the most challenging and rewarding effort in my life. I live and work in a smallish town outside of St Louis, Missouri, USA. I spent 20 yrs in telecommunications with a Bell company and when downsized and out went to work at a local factory and am enjoying the change.
