gracious me, sounds like an 86 nissan sev6 pickup that i had...spent vast amounts of $$$ to find out after an inordinate amount of time, money and frustration that the wheels had not been properly torqued on after each attempt to solve the shake, rattle and roll. each removal and replacement without proper torquing changed the vibes to a different speed and sensitivity to road conditions... no 2 road rides produced the same results.... frustrating as hell
