Default 2003 WRX popping

So my 2003 WRX makes a really odd pop when backing up or going forward from a stop, this i can feel in my pedals mainly clutch. Also all four axles have been replaced recently and clutch flywheel are less than 6-7 months old. I have been reading a lot of articles and all are saying axles but they are new. I did read that if the rotors and pads get warn they can cause this, true or false? Also what should i be looking at to help diagnose this?

Mine does it too. Havent figured it out yet. Only usually when its cold and I acellerate to the end of the driveway then pop right when I hit the break. I thought it was pad knockback due to the non husky 5x100 setup. People who do brembo swaps say it gets really bas. Another reason the sti has beefier hubs and axles.

Another thing i forgot to add. If i turn the wheel all the way in one direction while backing up its knocks pretty dang hard almost like you hit something. No idea what this is but wondering if its the rack.

I had an issue of the power steering line vibrating and smacking the frame once. The subaru tech reached down and belt the hoses back and never had the problem again
Down inbetween the heatshield for ur downpipe and fender while looking at the engine from passanger side. The hose has a flex tin foil type heat shield hose around it. have someone turn the wheel while u listen. Dont burn urself!

This only happened pulling out of the driveway and turning the wheel too. The other issue still happens and comes from the rear. Likely the pads and rotors and clips in my 4/2 pots. Could be worn clips on ur sliders too.

Those ball joints are brand new literally. I got new shocks and springs to put in with my radiator and transmission. Hopefully I'll see something before its too late.

Could be a bad wheel bearing. Mine went 90k, 120k, 150k. I replaced the last one before it went bad.

Take the wheel off and rotate the hub. Listen and feel...a good bearing makes no noise and is smooth. Suggest you compare to the other hub.

When I first did my struts it was doing this I discovered it was the struts not being tight enough on the mount it was poping from up and down movements quick blast of the impact fixed the problem hope that helps at all

I am sorry Aaron. I am looking for info to inspect while replacing these guys so i dont finish everything and then still have it. I see no power steering fluid on the ground and i am also loosing none. My shocks i was told are bad, both wheel bearings, axles, lower ball joints are brand new. Sometimes it sounds really bad other times it a faint knock. Mainly occurs when backing up with the wheel turned, also has a tendency to change sides. Like this morning i felt and heard the knock from driver front. Yesterday it was passenger front.
