I have a 93 Deville. Tires are about a year old, but only have 5 or so thousand miles on them. Car has 119k mikes. When I go over a bumpy road the front is real noisy, sounds like a popping noise from my front passenger tire. I looked at the tires and they look to be wearing evenly, and I didn't see any cupping. I took it in for an alignment as it needed one anyway and they said that the tires were messed up on the inside and that they rotated them for me.
I went back to where I bought the tires and they say they cant find any problems with them.
Speed doesn't seem to factor in, though I am usually going under 40 when I hit the bumps / uneven roads and the car feels great on a nice flat road.
Does this sound like a tire issue, or something else in the suspension?
I paid close attention to it today and think it is something in the suspension. When I brake from over 15 or 20mph I feel / hear a popping noise coming from the drivers side front wheel so I think something is messed up that effects both sides, sounds like two loud pops in succession. I was rear-ended a few months ago and never noticed this issue before then. When I was hit I had my foot on the brakes and actually pushed them harder since my car never moved forward at the tires, just pushed a bit with the wheels locked.
I am thinking that something broke when I was hit and is now really starting to show it. I am afraid it will fail totally before I can track it down, any ideas where to start? I took the passenger wheel off and nothing immediately jumped out at me, havent had a chance to get under the car though.
