I took my tornado out the last 2 days well today i put on the new wheel hub and after i startd running when i applied the brakes it makes a grinding noise. Ive checkd for rocks and used an airgun to blow the dirt and dust off. Any help would be greatly appricated.

what do you mean a grinding noise? is it coming from the brakes, the diffs, where is it coming from? If it's coming from the brake pads don't even sweat it as long as it runs and stops, no big deal, just dust on the pads or the rotors.

im not sure where the noise is coming from. When I pick the car up and gas it to half throttle and apply the brakes it is fine, when the car is on the ground and i run it to a qtr throttle it makes a noise kinda grindn and a popping noise almost like the dog bone fell out but its ok. Ive got no idea of what it could be. Help Me

LMAO, well it's hard to help if your not sure where the noise is coming from. I would suggest checkign the dog bones when it's sitting on the wheels, check to make sure all four wheels are spinning, hold it up or set it on a block so the wheels don't touch the ground and give it alittle gas. If one of the wheels isn't moving you could have a differential issue or a loose drive cup. Could also have spur gear teeth taking a crap.

ok i took it outside and ran it with the body off. I think the noise is coming from the drive cup at the back of the brake. I also noticed that the drive cup had to marks where the dogbones are starting to make grooves in the slot in the direction it turns. Now what??

now what nothing, that happens it's normal, the dogbones wear at the drive cups. The better question is, Are the drive cups tight?

im not sure how to check that.

wiggle it with your finger or a screw driver see if it wiggles likes it's loose.

ok i checked all the drive cups to find that the front drive cup to the frt transmission is loose wiggly bad

There's your clicking noise. Tighten it up and see what happens.

well its tight and it was a lil loose but i still think that the front differental is possibly goin bad... the wheels spin the same way when i do it by hand they will go the opposite way sum times.

that's normal, you have to give power from the main center input drive for them to spin the same way. It's because of the planetary gears that makes them spin opposite when you spin one wheel with your hand, that's normal.

well its dark so i cant runnit cuz my daughter is asleep.... hope you will be on tommorow as i will test this after i work 12 hrs and will be home shortly after 7pm. thanx for the help so far. cam has been a great help on my other probs so youy 2 guys r my goto help. thanx again

It's no problem. What's your other problem?

Well i finally figured out what the problem was and it was the front differental had 6 teeth gone. I got a new gear set and bearing, installed them and YES!!!! No more noises. Man back to maken the fast passes by the neighbors houses. Waitn for the cops to come as I guess they were lookn for me the other nite when I took it out to test it without the front drive dogbone installed. LOL COME AND GET ME COPS!!!!
