Jeep started extreme shaking while driving.
Twice my jeep started shaking severely while driving. First time I was slowing and merging into the left lane to turn off the freeway, the shaking lasted about 10 seconds. Last night I was driving 65-70 mph on the freeway when it started, it lasted about 20 seconds.
Prior to these events I had most of the suspension replaced, alignment and tires rotated and balanced. tires are in good condition.
