front end shaking hard
when driving the front end shakes really bad
The Nissan Altima is a mid-size automobile manufactured by Nissan, and is arguably a continuation of the Nissan Bluebird line, which began in 1957.
Start with the brakes and rotors. Check the pads for wear and consider replacing the rotors or at the very least having the rotors turned at an auto parts store, or a garage. A word of caution in turning rotors though, it makes them thinner and thereby weaker and they will tend to warp easier next time you drive.
Have your tires balanced and if they are worn, it could cause shaking and shimmying. You may want to replace those too. A cheaper option than new tires would be used tires at your local tire store. I have done this before but of course they need to be replaced sooner.
Perhaps replace or repack your How to replace front wheel bearing, in FWD vehicle.
Check the possibility you need new front struts.
