why you shaking

ok, so this is my first XJ well jeep period and im still learning about it.
im not a big mechanic and was looking for advice on how to get my xj to stop shaking at 50 mph ive been told bad shocks and or brakes and rotors. When doing 50-55mph and I go on the brake the shaking is twice as bad. its not the rotors because i've already replaced them along with the pads. i just put new shocks on and the shaking got worse. i have already rebalance the tires which made it better but after the shocks it was back to where i started. ANY SUGGESTIONS WILL BE HELPFUL. i've already put well over a k in parts because the previous owner was clueless about taking care of the jeep.

My xj did this when I had mis matched, un evenly worn tires. I have a 3 in lift and running 31s. I tried putting the most squared off ones up front, and still, awful death wobble between 46-48 mph. Started off as a sometimes thing and eventually it happened every time. Funny, but the more muddy the tires and rims were, the less wobble I got. Finally got a set of evenly worn tires and had an alignment done, and of course, balanced the tires as best as humanly possible... No more shaking to the point of a full on wobble, but it still has a small 'shimmy' that doesn't bother me at all.

Ps, When I took the old tires off, I hosed down my rims and got several pounds of mud off that was caked on, too.

ya i got some uneven ware to the front tires but thats how they were when i got it,didnt know if that would be a factor since i balanced them to their current condition. ill check it out im gonna switch them to the back and see if there is a difference because the rear tires are practically new.

My old, uneven tires were balanced, but because my alignment was off, the balance wasnt so much a problem as was the alignment was all out of wack.

If you have two good tires, why not try to find another pair of evenly worn tires and ditch the un even ones? I would bring it to an alignment place once you have four tires you feel comfortable using for a little while...that way you won't be incurring the cost of an alignment more than once in a short amount of time. Switching the tires you have now may by you some time, OR you may end up wearing those like-new tires unevenly, too.

Imo, don't let the death wobble go on for very long or risk more damage and more repair bills to other parts of your XJ. This will not just affect your tires

I've had all sorts of wiring issues with different car stereos too... Seen some interesting wiring that people have done. Do your front speakers sometimes work and sometimes not or are they not at all working?

After installing my 3" lift from RC, i had lots of rear vibrations, did a TC drop about a 1/2" and that stopped that. Also my old tires were over inflated and pretty worn down, about 30% tread. I replaced them with some 32" bfgoodrich and aired them down to 20 psi and they run amazing. I drive it down the interstate at 70mph, around town, and gravel trails. Cant feel anything, i love them! But i still get the death wobble at about 50mph, thats because since the new lift and tires i have yet to get an alignment and now i need a balance, doing it today though so hope it helps!

the previous owner said sometimes when you hit a bump they try to work and make a weird sound but that has yet to happen for me all four door speakers dont work im currently just using the rear speakers

The same thing happened in my Yj, the speakers would go in and out. I took out the head unit and there were some wires barely connected, just hanging there. Plugged back in and presto, all speakers working. Probably an easy fix, even if it isn't that
