    Exclamation I need help

    hello people i am new to this. i recently bought a 2005 wrx sti and i need someone to help me figure out if my rear differential is bad. this is what i fell at about 5 to 15 miles per hour specially when i turn, i fell vibration and i hear like something wants to break like poom, poom, poom in the back of the car. other than that i can do 120 mph and zero noise back there. if someone can tell me what it is wrong i will appreciate it.

    The key is to pinpoint exactly where the noise is coming from, then disassemble and check. If it's when you turn and coming from the rear it could be the rear diff or it could be drive shaft bind, maybe bad U joint. To check the diff, need to drain it, remove the cover, check the gears and bearings inside.
