you mean put them in the outdrives at the ends of each center drive shaft? I thought the noise was mainly from the pinion and spur? Either way ill try the oring method but man my truck just gets louder and louder and sounds like somethings wrong and ive maintained and replaced religiously since i got it a year ago. It seemed to get better when i installed the straight cut gears.

Yea I already have all that done, Ive had the car for over a year so Im pretty familiar with it and definitely not adding more weight to it, the truck has plenty of weight so wouldn't advise that as a tuning option but if it works for you then go for it.

regarding removing the rear chassis brace and diff cases breaking... you can leave the rear chassis brace on and just leave the screw(get a longer one for best results) connecting brace to rear case only half screwed in... this way you still get the chassis flex but less likely to have broken diff case

Yeah I understand that. Mine was super loud too until I did the oring trick. There's a guy at the track whose truck sounded like an electric chainsaw. Had him do this too and he was amazed.

Thanks for this tip! I'm going to try this one out.

The reason why I added lead weights to the rear was because when you remove the center and rear brace the rear end is much lighter than the front end. It seem to come down the fishtailg out of the corners a little bit .

I haven't had the rear diff case crack without the rear brace . I may put the rear brace on without the center brace and see how it is .

My truck drives awesome ! I must have gotten a good one .... I feel bad seeing what all these people are going through to get theirs to drive good. I dont normally get lucky , but I must have this time...

what black orings
do have more info on this?

I'm guessing it's the ones used under the ESC tray and as shock down travel limiters.

First day with mine I got the TQ and won both mains. Felt like the truck did good but just didn't feel "right". A few practice days and three races and I TQ by a lap and lap the field. Now if I could just stop snapping these damn axles.

Might try boiling the Borrego wheels to get a little flex out of them...

gear mesh is touchy. if you open up your mesh a little more than you think would be good it makes it smooth sounding. i know you are probably good with setting the mesh but the sct410 seems to like a little wider mesh than im used to.

Correct.

that used to happen to me and it is frustrating when the rest of the body is good and it wont stay on cuz the clips tore thru I switched to the proline mounts and that part outlast the rest of the body now, i am never switching back

make sure your motor didn't shift, sometimes after a big hit it will be at a slight angle causing excess noise because the spur and pinion are not in a straight line I switched motor mounts and now my truck is super quiet even without the orings, the stock mount has too much play and it's weak.

Yea i noticed that also . It may have something to do with the motor alignment or the teeth size on the spur.

Yea i dont know if it has something to do with the thickest of some bodys around the body post area that causes that. But its two bodys which were used even with shoe gooe around that area the body clips would rip into them.

All day i was running the truck with three clips with one side flipping up in the air . The last main i was in it just got worst and ran without a body.

So il need to use them body saver spacers on the new body !
