ok, im not sure what stock part i need to replace on my emaxx 3905. one of my front wheels wobble for than the other 3. the wobble im talking about is...you know the part you tighten with the grey plastic suspension multi-tool, i believe its called the pivot ball caps.
when those ball caps are not tighten the wheels tend to wobble right and are loose fitting. thats the type of wobble im getting now, But even after if i have those pivot balls very tight, the wheels still have wobble.
i know this was caused by too many cartwheels.
anybody know the name or part number i need?

You need to take it apart and start inspectiong things. It might be as simple as replacing the bearings. The hub itself might be worn out. The pivot ball could be damaged or you may just need a new cap. Really hard to just take a guess from an explanation. Grab your 2mm and 2.5mm allen wrenches and start disassembling!

Sounds like bad bearings... Or maybe a broken hub...

Hub is the thing the pivot balls sit in, and it has the wheel bearings in it. Sounds like a wheel bearing to me.

if you still have the stock plastic knuckles id say its the pivot ball bushings need to be tightened or are worn out, STRC makes some really nice knuckles

It really just sounds like the wheel is out of round to me. It was hard for me to decifer the problem from the grammer, though. I believe that you are saying one wheel wobbles more than all the rest. If it gets worse as you go faster, its probably just a tire out of round. If you can grab the wheel and "wobble" it up and down(like checking a wheel bearing in a car), try tightening the pillow balls. The "hub" that someone refers to is actually called the axle carrier or steering block. Very cheap but either its broken or its not. A picture would help more and a video would be definitive.
