jsl6v8: To replace the front belt on the T2 you will have to remove the top deck, rear plate and the aluminim front shock tower mounts, from their you remove the belt from the diff and top shaft, then will have to un-screw your left steering turnbuckle to slip out/in the new belt, then replace everything. It could seem like a large job but its not as bad as it seems. Once you do it once or twice I bet you could do it in 10 min.

Hey guys,
Noticed tonight that my car seems to be excessively noisy compared to the other cars I run against. Mind you, I felt like my gear mesh was perfectly set...
What are some things that can contribute to unwanted drivetrain noise? I run an Orion brushless motor, which I know is supposed to be noisier due to the internal fan, but I still feel like something small is clicking sometimes. One of my front drive shafts are just a little bent - could that be the culprit? Should I replace all the bearings? It's really beginning to bother me...
Thx...

Stickyfingaz: I think that it is your motor, just take it out of the car and spin the pinion gear with your fingers and you will know if its that. I have used similar motors and it happens. it is easy to fix, you have to take off the pinion and the front bell so the rotor fan is exposed, I have fixed it in several ways (1) Just taking out the rotor and putting it back in, (2) removing the center aluminum sleve of the can, and leaving it off (3) simply taking off the front bell and putting it back on. I think that the noise is just an alignment issue of the rotor. I think that no 2 works the best.
BSchorr: obviously the aluminum parts are stronger than the plastic, and the other advantage to the aluminum is the stiffness of the part. (example: if you ran aluminum rear uprights all of the flex is now coming from the arm only. on the track this should reduce the amount of rear grip (By Just a little) and make the grip more consistent do to the reduced flex. This is why alot of people use the aluminum parts with foam tires.

Sometimes the extra noise comes from a damaged spur gear or pinion, it worths to take a look at the gears or just simple replace them to see if the noise goes away...

crown gear
Are there any after market crown gears 100 tooth that will work on a 007.I am running 13.5 brushless and am trying to gear it down enough.

When moving the belt on my t2 the car feels really tight, I'm guessing the bearings, but is there anything else that can cause this, I took off the front belt to test the rear and middle of the car and then took off the read belt to test the front and middle both times the car felt tight, so I'm guessing the rear but it also felt more tight when testing the rear than it did the back, so I'm not sure if this means that my middle and front bearings or shot or if its just because of the longer belt. Also what sizes are the bearings, both sizes, at least I'm assuming there are only 2 different sizes in the car.

jsl6v8: in the drive train their are 2 kinds of bearings, their are 10 5x10 bearings and 4 10x15s, Like you said it sounds like you may have some bad bearings, otherwise your belts could be to tight. during assymbly their is not really any screws or anything that you could build wrong to make the drive train bound up. the only thing could be if you have any screws too long in the outer cabmer links that may be running all the way down to the axle bearings.
