So the back story, mom mother bought this jeep new in 1997. I have always had sports cars. She gave me her jeep a year ago. The jeep was a daily driver and taken car of. Only 101,000 miles on it. Stock suspension on 31 x 10.5, 8 inch rims. My question is, when I drive around it feels very shaky when I hit bumps and just a general loose suspension. Do you think I need to get a new suspension? I plan on lifting it soon 4 inches to put bigger tires on it. But don't know if I should do it sooner than I plan or is this just how keeps feel to drive?
