There is some left-right movement in both front axles...not a lot. Is it normal to have some play, or should it be tight? Boots are fine. Noticing some humming/vibration as I drive and seems to be coming from the axles. The humming/vibration increases when I start to break. I have a 2002 Accord and checked the play in the front axle. The Accord also has a little play. The front tires on the Civic are running on the thinner side. I switched front tires with the rear tires, which have a thicker tread. There is now no humming/vibration! So, I must conclude, I need some new tires. Any comments or suggestions ? Thanks
