It could be that you have a bad tire or a tire maybe not balanced correctly anymore

Have your car raised up to check the engine/transmission mounts. Also the turbo-charger needs inspection to be sure carbon deposits not
affecting its rotation

check your engine support, if it is ok check your tie rods and stabilizers or might as well have your wheels aligned...

SOURCE: During highway driving, my 2005 Ford Excursion

I would first check the u-joints on the driveshaft if the problem only happens when the speed is between 62-75mph. Then check all the tires for lumps or bulgesin the sidewall or tread surface. The tires may also be out of balance and bouncing at that speed. If the vibration occurs only when the engine is around 2000rpm, check the pulleys, serpentine belt and anything driven by it for looseness. Also, check the trans mount to see if it is loose or broken. If everything checks out ok, have the OBD codes checked to see if anything might be causing the engine to surge.

I have a 98 Bonneville with a bad vibration at 65 mph,new struts, new jack shafts, new front wheel hub assy;s new cooper tires, new motor mounts. Do you have answer?


This most likely may be due to the new tires... make sure that they are balanced correctly... 1 out of 10 times this will happen and you should only be able to feel it at certain MPH... somtimes worse then others.

2001 Bonneville steering wheel shimmys very bad when you apply brakes at 50 mph.


99% of the time this condition is caused by out of round brake rotors. You will have to either have the rotors machined if they are thick enough or replace them. If you price them out you will find that machining the rotors will only save you maybe $10-20 each.

Intermittent vibration coming from engine while a/c running


Change plug wires. Most often, plug wires will only short out when they are under load, so you don't notice anything until your motor is doing a little extra work.

Vibration in 2001 Dodge Ram 1500 (YES, this is a double post)


Could be u-joints. My wife's Pathfinder developed a vibration at highway speeds. A little research revealed the front driveshaft u-joints bearings would begin to fail causing some play. Took it in to have them inspected and sure enough- the little needle bearings were grinding down to dust. Replaced with greesable units and vibration is gone.
Certainly worth checking out.
