Hey guys I got a set of Mickey thompson BAHA ATZ's about a month ago w/ a 2in level kit..... When I go around 55mph my truck shakes bad and it is from the back. I can see the bed of my truck shaking violently in my mirror. But if I go faster or slower it will stop and be smooth again. The place was suppose to do a balance and alignment on my truck after the install. Is this my tires or something else??

 

sounds like your tires are out of balance. take it back and have them re balanced.

 

if that doesnt work then you might have a tire with a bad belt! although very uncommon it is a possibility. i have never rode on a bad belt but i know it will shake your brain loose!

 

thanks for the info guys im taking it back tomorrow

 

Since you have an 05, make sure they do a road force balance. Very important when you are getting vibration on the 04 up.

 

sure thing..... preciate the info

 

Truck is prolly way to new for the U-joints to go, but you may have them checked as well. I had an Explorer that would shimmy bad at 55, and it was a bad U- Joint.

 

Could i do a U joint inspection myself?

 

Any pic of your truck with the ATZ's?

 

 

any info on the tire problem?

 

nah I hadnt really had time, school is killing me this week, hopefully i can get it done friday afternoon, once i get results ill post ASAP

 

ok sounds good

 

Dude i have the same exact problem! I have the same Mickey ATZ's and on the freeway looks like my bed is on springs. Did you ever figure what the issue was?
