I have 1997 Mazda 626 I4 5 speed manual transmission with 140k on it.
All of a sudden I am getting a horrible reoccurring vibration and noise that sounds like I’m driving on a rumble stripe at about 60MPH coming from the front end when accelerating.
It speeds up as I accelerate.
If I push down my clutch or let off the gas it goes away immediately.
While turning right it will go away immediately until I straiten it back out.
It happens in any gear at any speed in any weather although it seems more likely to happen when everything is cold.
It isn’t always there and there seems to be no rhyme or reason as to when it happens or clears up.
