    I have a clunk/pop that is growing more frequent and is starting to worry me. All I know is is that it is coming from the front of the car and is random. I can be going fast or slow, hit a small bump or a pot hole and it will occur. The part that bugs me is that it's completely random: I can hit a small bump and the car will pop then I can hit a pot hole and it won't do it. Sometimes it will occur when speeding up from a stop. Doesn't matter if I'm turning or not either.

    I haven't looked anything over in detail yet but I have turned the wheel stop to stop and didn't hear/feel anything as well as bouncing the car up and down without anything. The dog bones and motor mount are all relatively new, not sure about the tranny mount. The car handles and drives fine.

    Anyone have any ideas towards this?

    A random pop or clunk, look for broken springs

    Might also check your strut mount.. We recently replace some on two different cars where the yolk was not even connected to the outside rubber hence the pop.

    I looked at the springs and they seem to be fine. I have noticed that it seems to only pop at speeds under 30, and there is no popping if I am doing some serious cornering. It really only pops under like light driving conditions and small bumps at random. It isn't consistent at all.

    Sway bar links can cause that type of noise also

    I have the same problem, mine mosty occurs during moderate stopping accelerating. Was told by a local garage that is was a sway bar link. I replaced the one they said was bad and it still "clunks". I then replaced the remaining 3 and still have the clunk. Everthing seems to be pretty tight when I checked it out while doing the sway bar links. I am leaning toward a strut. What exactly do you look for when inspecting a strut?

    Not sure, I know when I grab my tire and rock it left and right, there is hardly no play in it at all. I wondered about CV joints too, although they usually clunk-clunk-clunk on turning. hmmmm.......

    Sounds like this is sorta common. I did notice to that is usually occurs after braking. I can go over speed bumps but the clunk isn't there. I'm going to dig into it this weekend.

    was looking at that last night. Do you know if those bushings can be replaced without taking the hub and carrier off?

    The bushings are riveted/pressed into the control arm so you have to pull the arm to replace them. The hub can stay, you just have to pop the ball joint off. I'd unbolt it from the strut and leave the axle and brake attached.
