Which vehicle is it specifically? I did a quick google search and it appears to be a 1/8th electric buggy. The photo I saw shows it has a built in servo saver with a nut on it. Those can sometimes loosen themselves up due to use (arrma's are well known for this). If it has self loosened, you would lose steering quite a bit. I had that happen on my outcast frequently and ended up buying a saver post that had a split nut you could lock with a screw. Short of that, tighten it all the way up, put some loctite on the threads, then back the nut down over the loctite and let it setup. That is, if yours has moved itself.
