i have a 89 jeep comanchee, 4 cyl, manual transmission, 2wd. my truck vibrates horribly at 35 mph. it used to start vibrating at 70 mph. but here recently it has been at 35 mph. i have brand new tires. i checked and repacked my front wheel bearings. and it does it at the same speed no matter if im in 3rd, 4th, or 5th gear
