Default PLZ HELP!

ok heres da deal, ive got a tamiya stadium thunder and ive got a problem with it theres is a loud annoying crunching sound coming from the rear end, i thought maybe something wasnt meshing in the gearbox so i checked it out and everything was fine, so i decided to re-grease everything and pulled apart the diff and greased everything alot, but it seems to be as soon as i put da motor in, and theres a load on the motor it makes a crunching sound, can any1 help me out with this!

You might want to check the gear mesh between the motor and the spur, and also check and see if there is anything stuck inside the motor like a rock or a screw.

Maybe the motor screws you are using are too long and are grinding in the motor.

yo chk it its could be that if youz gotz bushins in ther they might be worn out witch wood mAk teh geers come outa mesh it sounds like its probably the diff, but you might also want to check out your drive axles, wheels and wheel hexes. Also take the pinion off the motor and see if it spins smoothly, and then while the pinion is off hold on to the spur gear with your thumb and roll the back tires on the ground and see if the gears skip. One other suggestion, goto english class.

Well, bushings are used in place of bearings. They are usually a little piece of plastic or copper which supports a spinning shaft (wheel axles, transmission)

You can't exactly expect your drivetrain to be free of any skips if you only re-grease it. You must clean every drivetrain part and look at them carefully for any signs of strippage (missing teeth)
