I own a 98 Jeep Cherokee Classic and at 50mph and above while im driving if I hit a pot hole or even as light as making the transition onto or off a bridge my jeep flies into what ive heard called "The Death Wobble". The steering wheel starts shaking left to right and the only way to get it to stop is to slow down to 40~50 mph. If anyone has any idea as to what would cause this or has also had this problem and knows the resolution I would love to hear it. Thank you in advance.
