I have a 2000 ZX2. I have replaced one of the front lower ball joints so far as well as fully inspected the front end with it completely off the ground. I have a noise coming from somewhere in the front that can be best described as a clunking. I can not get the car to replicate this when up on jacks. It seems to happen when I take off from a stop but it also happens if I go over the curb when exiting my driveway. interestingly enough it does not seem to happen when I hit traintracks. I am relatively certain it is not anything suspension related (ball joints, lower arm, strut or spring) but I am not going to discount suspension being the issue, I have not checked the sway bar... I am not sure if it could be CVs popping in and out but it does not happen more or less when turning so I know it at least isnt outer CVs. It could also be engine mounts, I am not sure where those are on this vehicle. I have had the car for about 3 months now, I purchased it for $700 so I pretty much have been just driving it until something breaks then I will know what to fix. Would be good to get some insight on this issue though if anyone has had this issue before. The car has also now started to keep the E brake light on even if the E brake is off. Why could this be? My E brake 'works' to some extent but I do not rely on it. On the car I have replaced: FR Ball joint, Rear strut, 2 rear brake lines, fuel filter, MAF sensor, spark plugs, air filter, full oil and filter change.
