I have a popping/binding noise coming from my car (06 WRX, 5MT). Thus far it has only happened in reverse, and has also only happened when the car is cold (sat overnight / more than an hour). It doesn't feel like it's hesitating to move - my driveway is on an incline - but I can FEEL and hear two quick pops in the car whenever I'm turning and backing up slowly.
Try as I might, I cannot get the car to do this once it is warmed up OR while moving forwards - I tried doing slow turns at lock in first and reverse with the car warmed up and could not replicate the problem.
Edit: Also, it only does this once when it's cold, as though something is popping back in the place. Maybe I should try parking without the e-brake set to see if it's sticking? It has been pretty cold here the past couple of nights.
