So with a 2 inch lift in the rear and all stock up front with all brand new front end steering components and 153500 on the clock I took a trip 160 miles round on the highway through pa. The longest I've ever driven this thing!! I set the cruise control for 70 and the jeep did stellar couldn't ask for a better ride except my *** went numb. Now the wind was the huge killer trying to keep that thing out from under semis and from driving off the road or into somebody was a nerve racking feat but manageable!! I felt like the semis crossing over the center line hahaha. The ride was smooth except for a deathly vibration around 63 mph that seem like the car is on a paint shaker haha!! After 63 all the way up past 100 is rides like its on a cloud with no problems, Raced some dude in a newer Honda civic with a fart cannon he couldn't hang even after getting a jump on me hahaha. Could the vibes be caused from front cupped tires ??

 

Could the tires be out of balance?

 

If not new tires, U joints could need greasing or replacing. (slip yoke too maybe)

 

Something is way wrong @ 60 mph on the highway I barely have to keep my hand on the wheel.

 

My daughters on 33's cruised 80mph all over Florida picking up parts with no problem, Same jeep and lift on 30's drove 2100 miles from Florida to Chicago and back pulling a U-Haul trailer

 

Two brand new tires mounted and balanced rear two very old tires front that are cupping u joints and slip yoke have never been greased

 

Well it's only if it's super windy which is was that days going through the hills of PA

 

Mine handles like crap ALL the time, but I still drive it to the trailhead. After about 3 hours or so, you don't even notice you are having to work at keeping it on the road! (6.5" with 35's!)

 

haha well I'll be making the same trek again friday morning and then driving it the whole time I'm there I will say another thing I noticed is how good is handles at 85 going around sharp bends on the highway i don't feel scared i feel confident and thats with a stock way bar and sway bar bushings!! I know in my 80 cutlass you were ****ting yourself anything above 70 around corners!!
