one year ago, changed spindle, and front half shaft. --- within 6 months, my rotor began to warp, changed rotors, brake pads, caplipers.
3 months later rotor began to warp again, feel a vibration when braking. Also, when lighting braking, slowing down for a stop light (under 10 mph) feel the brake catch and release, and it feels like the car is wobbling side to side. This is very uniform wobble, and not random.
At times the front left brake smells warm, but not all the time, it is intermittent.

CV joints are now clunking and need to replace again --- what would be causing the brake issue, and why would my cv joint go out so quick?

Would the spindle have play in it that would cause this?

I can replace these components again, but if something is causing these to go quicker than normal, I want to hit the root cause.

 

Yes, spindle play will cause this. When a spindle has too much play in it, it causes the brake rotor to move around in ways it isn't supposed to. It puts the brake pads in a bind every time you use the brakes.
