traxxas 4tec, grrrrr

[xxtcrageless]

Alright two traxxas 4tecs, all stock, lower screw keeps pulling thru the hub carrier (lil "c" shaped piece) on the front, besides new aluminum, has anyone used a conical washer to stop it or similar idea, what lightweight body options are out there, i know J-concepts has one at the local, i want something different, what other issues pop up with this car, just started running it

Are you talking about this screw?

You can try a plain old washer between the spacer/bushing and the C-Hub. More surface area will help. If it's already stripped you might be able to use in a 4x10 screw and a larger diameter spacer.

ok, to add to this, we had our last race and couldnt get the sons car to drive at all, upon inspection (dumb me not doing before) the front bulkhead screws had pieces of zip ties used so the screws would grip, lower part under the arms were missing or trimmed pieces of plastic, and there was a lot of play on the arms for ward and backwards, front and rear of the car, thought about going aluminum on the bulkheads and a-arm blocks, unsure if more will break, you can grab the front and rear and twist the whole car flex's and all hardware is (tight) guess I'm doing a complete rebuild

I would at least go through it and see what's what. No quicker way to end your fun than broken parts.

I wouldn't beat yourself up too much, there are much worse things that can happen. Your a good Dad just trying to spend time with the kids. If my Dad asked me to help on any project I was there. So don't discount getting them involved in the repair.

alright guys UPDATE... son of a B&^%(, i ordered an aluminum kit that had hubs carriers and arms, only issue I'm running into is... drum rollllllll the front suspension inner pins werent made right and i need to drill the holes out. dumb dumb can't make it up to his barn to get his micrometers, so would anyone be a pal and inform me what diameter the inner pins are, one car almost done and i can get to stuff, this way if i know i need a bit i know I'm not wasting my time, thanks guys, EDIT: part number shows it as 8340 but its a straight shaft no threads

You should be able to eyeball them with a tape measure. 3mm is about 1/8". I would guess they are 4mm. You should be able to tell if it's bigger than 3mm. But I was a machinist for 25 years. My eyes were calibrated to within a few thou

Use drill bits to mic it.

Yup, do this. Then break it off in there so you have a pin.

Hey now. I have actually done this. But I used a cuttoff wheel in my dremel

Why not??? Hardened high carbon steel with titanium coatings... drill bits are WAY better!!!
At least you did it 'the right way' and used a Dremel!
...break it off. Barbarians around here!!! Jeez!
