Driving down the highway at 60+ mph and sometimes even lower, my jeep will shake. It doesn't seem like a large bump in the road is needed to start it, but if there is one it will shake horribly for sure.
I've already loosened the track bar and lower control arms and shook the jeep and then re-tightened them. I've also gone through and made sure that no bolts were loose but I still can't seem to find the problem.
This is just one of the many issues I'm currently having with the jeep, but it's the biggest one and I would like to get it fixed as soon as possible.

 

Could be your tires need balanced or air

mine was tight too but it flexed bends , sorta id replace the stock one and use 9 /16 grade 8 bolts go from there

 

Try rebalancing the tires at a place with road force balancing

 

My tires weren't balanced properly by the place where I bought them. I had shaking at 45 and 60 mph. The manager said he would have had to use a ton of weights to get my Fierce Attitude 35's balanced.
Eventually, I got fed up with the shakes and went to 4wp and they balanced them without any problems, using a ton of weights.
So happy now and I was able to take the Jeep on a 10 hour trip without worrying about the effects of the shakes.
