Tamiya TB-03
#1501

Not sure if tamiya made a complete CVD kit for the TB03, but you need the following:
Tamiya (#54076) TB-03 Wheel Axles
Tamiya (#54078) 44mm Swing Shafts
Tamiya (#53500) C.Joint For Assy Univ Shaft
I use the 44mm shaft for my car, but the 42mm will also work if you use the spool with the stock blocks (1A).
Older TA05 universals will not work since the TB03 uses the updated 416 suspension axels.

You probably read my last posts. The CVD pin snapped in half and caused havoc and I had some vibration problems with the CVD.
Do you think it's better to go with 42mm upfront over 44mm?

I never had any vibration problem since I got the 44MM in front and with a spool. the stock one is another story , you can see on this tread a photo of my stock dogbone wear really bad, because the stock cup are too deep. if you keep the stock bone setup, grind a little the cup can help that or put some Oring inside the cup.
Driftwoof if I remember you were the one that want to max out the steering by any mean ( stoper of the hub into the arm) and I think this is where your problem come from. Like I already told you this is too much, you have to remember you have a IFS setup and this piece was made for 416 that dont have this setup. Personaly I keep a good amount of clearance between the hub and the IFS pushrod.
Doing drift or grip without the steering max out is not a problem for me I got all the turning radius I want and I even trim a little with the TX Dual rate but im more a throttle drifter.
For the MM in front ( Stock block), its depend of many factor and the camber is one of them. If im in drift configuration I put the spool in the back and I use 0 camber and my 46mm with allu diff work but are tight but 1.5 degree and more they bind. When im in grip setup I use some camber and the spool in the front so I use the 44 in the front and put the 46 in the back

I discovered a new setup I really like:
Direct Coupling Front/Rear, Center One Way Shaft(Square RC).
Only thing is, for it to work best I need to max out my steering.
44mm CVD Front/Rear
Wheels wobbled after the pin broken half in the CVD. The CVD is rough and scratched up somewhat dented. Im going to wait until the parts come in install them and see if it fixes everything. Then I am going to put some heat shrink over the CVD to keep the pin from falling out in the event it breaks again.

It's my fault for not mentioning this, but I have a TB-03D. It's not an IFS setup.

What motor are you running? The cvd will chatter at full lock. That's just the nature of it. Unless you use the DCJ shafts that is... Either way, you use a fast motor, try not to mash full throttle at full lock. or limit you dual rate. I drift a little too, but never had to use use full lock except to correct the car.
I just installed the EZRun 9T 4300KV Brushless System prior to the pin snapping. I ran Castle Creations 4600, 2 different Novak 8.5T 5000 KV, Tamiya 12T System in it with no problems.
The EZrun seems to have allot of lock. I don't know what could have caused it too lock maybe it just happen to snap was faulty.

I tried everything. Completely full new set of CVDs with new universal joints and pins, New C Hubs, New Bearings.
I tried 44mm Swing shafts, I am about to try my 42mm swing shafts. Hopefully the wheels will stop vibrating wildly when I turn. Hopefully. They don't seem to do it when the wheels are off though. WHen the wheels are off they "seem" to be normal I can full throttle nothing vibrates.
Here it goes. :/
Update: So tested the 42mm. Same thing. With the wheels off it's fine. Works great. I still have the rotor hubs on too so there is rotating weight when I tested it with the wheels off.
So I thought there was something wrong with the wheels. Misshapen, too much dirt in the wheels causing it to be off balance, weight difference or warping basically. I stuck on HPI rims with no tires and it's started vibrating like crazy again as soon as I started turning on my radio. It's starts half way down on the steering radius when I turn to test it. It runs smooth when it's running straight.

As you can see in the video, it runs fine straight. hen i turn it goes nuts.

thus the vibration also occurs when your car is running on a surface? try adjusting your steering end point adjustments. or check if there is too much slop or movement in the C-hubs

The C hubs are brand new, installed them today. Very firm. I never had a problem like this before.

I have lest then stock steering radius when I used to have a maxed out steering radius that would not vibrate. It used to be fine before the Direct coupling was installed up front. No visible binding.

I am also using spool and my car vibrates too same as yours, but its fine when im running in the track. the problem is if the wheel is spinning to fast vibration occurs in the arms, c-hubs and steering and my tires binds with the lower pushrod turnbuckle. but it doesnt really affect my steering.
I don't think it's normal. I email Tamiya but no response yet about it.
UPDATE: I found this article read halfway down. They call it "universal chatter"
#1511

Can't run a Direct Coupling without vibration upfront. So I ran the center one way shaft, direct coupling in the rear and very tight front ball diff. All I can do. I wish i can get the direct coupling up front though without problems.

so i'm having trouble deciding between the tb-03 and the tt-01e. which kit do you think is better in your honest opinion? thanks!

Hey Guys,
Back into RC after a 20+ year lay off. Must be going through some kind of a mid life crisis! Anyway, starting to build the TB03. Purchased all the recommended hop-ups suggested from the article on TamiyaUsa. Will primarily be running with other guys from my work on the street and in parking lots; long straights, wide turns.
Regarding diff assembly:
Whats a good starting point when adjusting the slip? Fully tighten, then back off 1 turn?
Should the ring and pinion be lubricated, or will that cause unnecessary drag on the motor?
Regarding upgraded TRF shocks:
Please suggest a good starting weight for the oil (will probably start with the 3 hole piston as recommended), and any hints you may suggest in their assembly.
Thanks in advance; I appreciate all the good advice!

As for the shock oil, I just use the AE45wt on all four. Can't get any MM oil here so I use what I can get. If it's colder where you are, you might want to try 35 or even 30.
