Tamiya tb03 help
I just got my first tb03 and love it now I'm finding out it's discontinued and parts starting to dry up. My question is does anyone know if the diff halves left and right from any of the other platforms like the ta05 can be fit with a little modification BC these s parts tree or diff halves look identical.

TA05 parts cannot be used, TB diff is more offset to side. TB04 and TB-Evo6 use same diff case, so you can use lot of drivetrain parts. Only big difference is internal gear ratio, TB04 has 2.6, TB03 2.4, so if you use TB04 diff gears, you have to use them on both ends.

OK one more question if I use the tbo4 or Evo 6 diff joints can I use the tb03 prop shaft pinions with those diff gears or do I need to replace my pilot shaft pinions as well?

If you mean those small bevels, no, you have to change them, too. Bevel gears are always paired.

The tb04 ball diff (#54522) should drop right in. It comes with a 40t ring gear so make sure you use it front and back or maybe try the tb03 ring gears on it.
I too just bought a tb03 (had one 5 years ago and missed it), you only need to buy the parts are unique to the 03 since a lot of parts are shared with the tb04

I d t have the carbon bridge yet and my car favors a slight right curve when full throttle, everything is set perfect, links , saver, servo centered all that it only does it on full throttle and it isn't torque steer bc its a brushed 23t. Any ideas? Could this just be the slop from the plastic bridge?
Problem of TB03 steering is, that bridge doesnt have bearings, making large play in right steering arm. That causes toe change on right wheel, which can cause uneven steering.

Hey dude that did the trick , but honestly my springs were way to soft in general so I put hard springs on with a hair size clip on the one spring and it tracks straight as an arrow thnx. Now if I could find all the upgrades I still need to finish the car out....So upset it's discontinued, I bet in Japan though you can still find the stuff easily.

I'm always so skeptical of overseas eBay sellers burning you, have you bought stuff like that bf? I really want a car rein chassis bad and your right I checked and there is a ton on there

i've ordered a bunch of upgrades for different cars from overseas ebay sellers and there is no reason to worry so long as you check out their seller history first. If it's good then generally there is no worry. Just make sure wherever you buy from has shipping costs listed before you commit to the purchase.
