Maybe something else? if it is engine related, you should be able to make it happen when stopped, by revving the engine. sounds like you must have the 2.37 axle if you cruise at those speeds a lot - rpm would be in the mid-2000s. i have heard of loose flex plates causing odd vibrations and even rattles. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
