this past weekend my front end got a good bit of attention. new hubs, cv's, and upper ball joints on both sides. did this partly cause I have a hummin/grindin vibration/noise that you can feel under my floorboard and through the steerin wheel. none of this solved that problem...so what could it be? I've heard maybe the u-joints on my front driveshaft could be shit but means how I just spent a good bit of money replacin stuff I prolly could have waited to do I don't wanna jump into this without it bein the problem. so any help would be appreciated!
