I have a .28 truggy and it squeels when you give it some throttle i dont no if it is the clutch bell or what but it only does it when it has tires on, but it doesn't when the tires are not on it, it only does it when it is under load.

Well... to me it sounds like a bearing issue or a brake setup problem.
Do your tires spin pretty freely when they are on and your truck is turned on( able to run your servos turn wheels throttle etc.)?
Check to see if your brakes are too tightly adjusted, maybe you mite need to adjust them a little. You should be able to role your truck across the floor with no resistance at all.
Does your clutch bell spin freely? make sure your gear mesh is not too tight.
Let me know how you make out!
