I suspect you are going to need a mechanic to look at this to determine what the problem is. He's going to need to hear it, and most likely drive it.
Part of isolating it down to the problem area, is to hear whether the problem is related directly to the speed that the tires are rotating (which also has brake rotors, CV joints, and output of transmission rotating at same speed), or at engine RPM's (internal engine, external accessories to engine, input shaft to the transmission).
I could interpret a 'chuck, chuck' noise to be a lot of things:
- brake pad worn down, and hitting metal to metal against high spot on rotor
- CV joint bad, binding as it is rotating
- valve bad in engine
- bearing bad in engine or transmission
- bearing bad on an belt driven accessory to the engine
- belt frayed and slapping
Grinding noise could be brakes, or transmission, or ??
Get it to a qualified mechanic, shouldn't take long to zero in on problem area.

Very common on 4 cyl engines that EGR valve gets gunked up with carbon deposits and starts to stick. When this happens the valve will stick open and cause a significant internal vacuum leak and will make the car quickly die as it tries to come to an idle. Usually restarting the car resets the EGR valve until it intermittently sticks again. Easy and cheap fix. Remove EGR valve which is in the intake manifold at rear of engine just behind the throtttle body. Clean the carbon out using brake cleaner and reinstall. You may need to replace the gasket between the valve and the manifold but this is a $1 item at NAPA. This will happen and will not always trigger your check engine light or throw any codes. 95% chance this is your problem.
#533 of 727 2003 Camry - Help!

I have a 2003 Toyota Camry, 4 cylinder. My check engine light recently went on. I brought it in for an emissions test and was told that I have a P0420 code for catalyst inefficiency where the rear catalytic is not working and needs replacement.
I also had a P0456 where an evap leak was detected. The fuel filler neck is leaking and both the neck and cap need replacing.
Anyone know if these are necessary jobs? Can I safely drive without the repairs (they're pretty costly)? Any help is much appreciated!

When you say the rear catalytic, are you referencing the 2nd oxygen sensor?
You'd have a sensor in the pipe in front of the catalytic converter, and another sensor after the catalytic converter. The computer monitors both of these sensors. Based on the sensor feedback, it adjusts the engine parameters like air/fuel mixture, timing, etc to get optimal performance.
If the computer is detecting the 2nd sensor is a problem, then we know the first sensor is working and it's able to adjust engine parameters into tolerance correctly. However, then the gas goes thru the catalytic converter and is read by the 2nd sensor. If it doesn't like the readings from the 2nd sensor, then either the sensor is bad, or the catalytic converter is bad. Sensor is the cheaper of the two, and they do go bad and need repairs.

I have a 05 camry xle v-6 with 25,000 miles which I bought new. Last week the check engine light came on and the car got real sick. It will idle but when you give it gas, it just won't go and there's a clunking in the transmisson.We had it towed to the dealer we bought it from and they said that they couldn't find anything wrong. The car was in there for 2 days and suddenly it started to run fine. Since they couldn't find anything wrong we took it home. 5 days later after running fine, it did it again. We'll have it towed again and hopefully they will find the problem. Has anybody out there experienced this type of problem with their camry.

They would be able to read the error codes from the computer. Ask them what the error codes were in the computer, when the worked on it the first time.
If you have to, you can buy an inexpensive reader and read yourself, I think I paid like 40 bucks or so at Pep Boys on sale a year or two ago.

The could not get the diagnostic reader to give any error codes. No codes to help with the problem. Took it home running about 25 miles and then the "check engine" light came on again and wouldn't run properly... about 2 mph!

I'd consider taking it to a different dealership.
