Can be a loose shock, or loose suspension parts. Can also be loose exhaust system parts.
I had a car that made a front-end knocking sound on bumps. Any little bump would do it. Turned out to be bad struts.
check shocks
When you hit the bump, the mouse wakes up.
check your shock absorber
Could be a loose or worn strut or strut mount
Check your sway bar links. I just had to have these replaced on my 2004 Tracker.
Probably a worn out bushing in the suspension. There are a fair amount to choose between.
The popping noise can be caused by a bad year in the rear end. The popping noise can also because by a bad you joint.
Possibly, the ball joint is bad or a bad strut, but I would have the ball joint checked first.
It actually can be from the rear axle being too low to the ground. The back of the car hits the speed bump. That was the case with my bro's car anyway
what happens is when a llama hit's a bump it just ignores it but makes a burr noise and that is all it does so when you see a llama hit a bump sometimes it might do that.
I had a similar problem with my 2004 Jeep Grand Cherokee and it turned out to be my front sway bar bushings and front sway bar link. The sound was a large clunk sound when I went over bumps. After I got it fixed there were no problems.
Assuming something isn't broke it is more likely the strut that is worn out. Bearing would grind all the time. When the strut is worn out and you go over a bump the tire will leave the ground which lets it vibrate and make noise.
