Pontiac Grand Prix Clicking From Axles

Problem with my 2004 Pontiac Grand Prix.
New tires, lined up,right sided CV joint replacement and seal. Question = car will click loud when gas is applied when driving. Also occasional jerking of transmission on take off from stopped position but trans fluid is @ right level.

Answer:
Since the clicking noise started after the axle was replaced, it may not be fully trans. There are several bulletins for transmission problems. From input clutch to second clutch problem. Pressure control solenoid, valvebody problems. Would need to be driven by a transmission Tech to begin diagnosis.

2003 pontiac grand prix still overheating.
Question: My car started running hot about three weeks ago. Heater would work on and off. Checked water and had oil in it. Replaced intake and head gaskets. Flushed Radiator. Ran fine for day or two. Started running hot again. Heat did not work at all. Changed thermostat. It was stuck. Flushed again. No change, still running hot.

Replaced water pump. No change. No oil in water, heat still not working even after new thermostat. Can idle for a while but when accelerated or tr to drive it instantly begins to run hot. Not sure what else to do. Any advice would be greatly appreciated. Thanks

Answer:
You've covered just about all the bases there, and with most of the parts that have been replaced, there can only be a couple things left that are causing your problem. Depending on how hot the car got, you could have warped or even cracked the cylinder heads. Just replacing the head gaskets wouldn't fix the problem, and this would lead to an additional overheating problem.

If the cylinder heads weren't checked out properly for cracks or warping during the repair, you may have to take them off again to get that done. Sometimes it's just a small amount of warp or the tiniest crack that can lead to big trouble. Since you stated that you had oil in the coolant at first, I would definitely be leaning towards a problem like this.

You could have even cracked the block if it got real bad. If there is enough damage, you will probably end up needing to replace the engine.
