That sounds like an alignment problem with one of the front wheels. A good resource is:
But, it can be a tad difficult to follow, especially if you have to use the axle slots (as opposed to drilling holes). Quite often you either get toe-in or toe-out. That means that the nails aren't perfectly straight going from front to back. I just had to correct this problem with a few of my cars. Start by pulling off one of the front wheels. Observe how the car rolls. Take out that front wheel and put on the other front wheel. Observe how the car rolls. If either one is dead-on straight, I'd keep it in and lift the front wheel so that it doesn't touch the track. This should make the car faster anyway. If neither one is perfectly straight (and that's more than likely the case), use small strips of wax paper and try to shim the axles one way or the other. For example, let's say that you only have one wheel on the front right side of the car and the car pulls to the right. You'll notice the wheel more than likely gravitates to the head of the nail as opposed to sucking into the car. I believe this is called toe-out. This means that the nail isn't perfectly straight (not up and down, but ratherm going from front to back). The nail is tilted towards the back end of the car as opposed to the front end of the car. Cut up some wax paper shim it into the slot. This is tricky and takes some practice. I cut up a square, fold it several times to form a nice wedge, and then try to keep it on one side of the nail as I push in the nail. It's tricky and you'll be cutting up a lot of wax paper. Anyway, if the car is "Toeing out", or if you just have the right front wheel on and the car is steering to the right, you need to shim in front of the tip of the nail. This will provide leverage to make the nail a tad straighter. It's all trial and error. I probably take each wheel off 10-20 times before I'm happy with how it's steering. Wish I could pay someone to do it for me

Also make sure that you did not sand the wheels at a taper.
