How are your tie rods? Every arrma truck I have I've had to replace tie rods.

I got my truck less than a month ago and it's completely stock, are the pivot balls/plastic ends considered warranty in that short amount of time?

As others have said, replace the pivot balls. But there will always be some slop. As long as it runs ok, don't go chasing perfection because the trucks a basher not a racer. You'll go down a rabbit hole of upgrades for little noticeable difference.

The plastic pivot ball acts like sand paper on the inside of the tie rod end. I really wish arrma would just use metal pivot balls. I've found that tie rods like these work great and stay tight even with tons of bashing:

Unfortunately they only fit the shorter arms. For anything with longer arms you'll need to just replace the rod ends and replace the plastic pivot balls with metal like the hotracing ones mentioned above.

Those seem to be sold out or expensive every where. I am curious what everyone else is doing for their tie rods. It's a big enough issue that if you don't replace them they just break and fall off.

Anyone else find a good solution?

I've not tried them so can't vouch for whether they work, but these traxxas parts were recommended on another forum.

Associated rc8b3.1 /81398 turnbuckle shoulder ball ,are steel pivot balls that fit into the arrma rod ends ,they take a lot of the slop out. Just expensive but they have lasted me 12 months.

Check all the connections, driveshafts to axles, wheels on the hexes, Hot Racing extensions on the axles. In the end, the 3s line has slop no matter what you do. I've done all the recommended upgrades, there's still slop, but my Granite tracks straight so I don't worry about it.
