Wondering if you have installed the Traxxas 3643's in the rear of your truck yet? I installed mine last night, and I'm having an issue with the mounting point rubbing the drive shaft.
I had this Problem too with my traxxas one at the rear. I just modified it a bit and took off a bit from the plastic mount.

It looks like the ball cup is not properly seated. Its fully seated yo one side of rge ball when it should be in the middle. You can also grind off part of the flange on the steel ball. Each side has a flange. Grind down the taller of the two. Use a small metal washer in place of the flange you ground off. I didn't grind any off mine. It rubs the drive shafts a very tiny amount but mine is installed with the shorter of the flanges up against the plastic and the taller side facing the drive shaft. If you ground off the taller side, placed a washer on the screw, and then screwed it in it would be just fine and would give you the clearance your looking for.

Reseat the ball cup on the steel ball for the turnbuckle end. Its not on properly.
Turn the turnbuckle so the longer of the flanges on the steel ball is facing the drive shaft where the head of the screw would end up being when you screw it in. Before doing that, grind off the flange I circled in red, put a small washer on the screw, and then screw it in where the washer would butt up against the ball of where the flange that you ground off used to be and the head of the screw. Basically after grinding off the flange it would look like a steel ball with a hole at one end and a short flange with a hole at the other end. I used a 2mm button head screw because the head has a very low profile.

Damn... havent noticed that it popped out. Thanks for that.
And i didn't have anything to grind it down that's why i did it that way and it worked fine. For the next time i will definitely grind it down and do it the different way
