DUDE CHECK YOUR BEARINGS!!
I had a vibration problem couldnt figure it out. I took it to shops someone said it was the driveshaft, another dimwit said it was the freakin tire. I changed the deiveshaft, nothing.
So one night after i was driving home from work i feel this big thump and jolt. Still couldnt figure it. So im driving home on Valentines day, i hear that thump again but two more thumps than i heard before.
I feel the driver side rear fall and see all sparks in the rearview. Just like the 4th of July. I look in my side mirror and something catches my eye, its my damn tire passing me up with the axle still attached.
Man, if that tire wouldnt have taken a short hop right before hitting the concrete highway divider, someone in oncoming traffic would of taken it right in the windshield.
needless to say my date didnt "up" any that night.
Check the bearings just to keep you and others safe.
