general problems of the 1996 Nissan Pathfinder

The problem started about a month after we bought the vehicle back in 2009, at first it would only start to wobble at 60 mph so we took it in for inspection they told us it needed alignment so we had it done. It worked for a while but then it started all over again and now at just 30 mph so we took in again, this time they did tires and balancing but it is just getting worse. I feel like the steering wheel is loose when it starts to wobble and like my tires are going to fall off. I try not to drive that car so much any more specially when I have my granddaughters with me. I would really appreciate any feedback you may have concerning the problem I'm having with my 1996 Nissan Pathfinder 4x4 thank you.

My problem is that I have a 1996 Nissan Pathfinder and when riding over 60 mph I start to lose control of my car because it feels as my car wants to tilt over. I don't know if there has been other complains about this but this has been happening to me for the past 4 months here and there. . Not all the time. I have taken control on the car by slowly pressing on the break and starting up again. I will be taking my car next week to the Nissan dealership since it's starting to get worse. My father is a mechanic and has been trying to figure out what is wrong with my car for the past few months and he finally told me to just take it to the dealer and they should be know.
