Thread: 1997 GT Weird Vibration

Ok,Here goes.267,000 miles,and box stock.When I first bought the car with the Shyte tires on it I initially thought THAT was the problem.New tires....no change.The front struts are new.Now,the issue.The car has a slight vibration when off the gas most of the time above 60 mph.When pulling a slight grade and the road is slightly rough it vibrates a little worse.The vibes do NOT wobble the steering wheel but,you can feel it through the wheel.The alignment is fresh.When we had it up on a friends rack we used a pry bar on the control arms and you can move them up and down a little,maybe half an inch.CV joints are stellar.It has been suggested that really bad rear struts can cause this.I am guessing by the look of them that they are REALLY old.To repeat,this vibration only happens above 55 mph and MOSTLY when off the throttle.It IS a vibe NOT a wobble.We have checked the wheel bearings,wheels,and tires a LOT!Sorry for the jumping around....I am Autistic.Any ideas would be appreciated. Thank you

If it was me, I'd make sure you don't have a bent rim up front and that the balance of the tires is spot on.

We have checked AND double checked the tires and wheels.As previously stated it only happens at 55 mph or above.

Yes,I replaced all the tires.I have noticed that the steering wheel has about a half inch play in it before it turns the wheel.The play is from the rack naturally.Would this cause the vibes I am experiencing?Also,would marginal control arm bushings or a right front wheel bearing that is JUST starting to get iffy do the same?

Just to update for anyone who G.A.S.Am going to do the wheel bearing and see if that's the deal since it needs to be done anyway.My VERY knowledgeable friend says it is definitely possible so.....we will see.
