Fairtax4me Posted January 22, 2017 Share Posted January 22, 2017 Might be an axle but kinda sounds like a tooth got knocked off the front pinion gear. Jack it up and spin the wheels and see if anything makes noise. Link to comment Share on other sites More sharing options...
louipaw Posted January 22, 2017 Author Share Posted January 22, 2017 Will do thanks! Do you think that is possible if my rack and pinion boot is torn? I've been riding with a torn rack and pinion boot for 6 months at least I will get back with more info as soon as I get it up on all fours Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 22, 2017 Share Posted January 22, 2017 Not the rack and pinion. Sounds like the Front pinion gear inside the trans. Link to comment Share on other sites More sharing options...
CNY_Dave Posted January 24, 2017 Share Posted January 24, 2017 (edited) 4x the wheel rotation speed. Driveshaft / u-joint or (hopefully not) a bad pinion gear. Edited January 24, 2017 by CNY_Dave Link to comment Share on other sites More sharing options...
idosubaru Posted January 24, 2017 Share Posted January 24, 2017 That doesn't sound good at all. If it was the axle I'd expect drivability issues. If it was a driveshaft i'd expect vibrations. I'd be thinking front diff - drain the oil and check for debris/swimming silvery stuffs. But things can vary so it's hard to say. Link to comment Share on other sites More sharing options...
3Pin Posted January 26, 2017 Share Posted January 26, 2017 Put it up on a lift and try to turn the front wheels while in park. Could be a broken short shaft ( between the axle and trans.) Link to comment Share on other sites More sharing options...
louipaw Posted January 26, 2017 Author Share Posted January 26, 2017 Not the rack and pinion. Sounds like the Front pinion gear inside the trans. Oh no! dammit man.. thats such a bummer if it is since i just got the tranny rebuilt like 6 months ago and I've always kept up with the fluid levels I have another video with a better view of where the clunk is coming from I'm uploading to youtube ill link it here when its done uploading i did the wheel rotation you recommended. In the video i jacked all four wheel in the air and put it in drive mode the front left wheel and axle to the front diff is where the clunking is coming from and is barley moving/able to keep up with the left from passenger side 4x the wheel rotation speed. Driveshaft / u-joint or (hopefully not) a bad pinion gear. Im hoping its the driveshaft/u-joint went bad! Will i have to take off the driveshaft completely in order to see if its messed up because i wasn't able to physically see any damage on the driveshaft or u-joint when I had the car jacked up and also removed the exhaust cover to get a better view of it. That doesn't sound good at all. If it was the axle I'd expect drivability issues. If it was a driveshaft i'd expect vibrations. I'd be thinking front diff - drain the oil and check for debris/swimming silvery stuffs. But things can vary so it's hard to say. It doesn't so much have a vibration to it more of a quick hard jolt every four-eight feet of movement regardless if going forward or backwards I am going to be draining the diff fluid to check for debris and will refill it. Should I do the same with the rear diff as well? Link to comment Share on other sites More sharing options...
louipaw Posted January 26, 2017 Author Share Posted January 26, 2017 thank you all so much! Im pretty bummed out I'm not currently able to drive my baby but Im in neck deep now and will have to fix it Link to comment Share on other sites More sharing options...
louipaw Posted January 26, 2017 Author Share Posted January 26, 2017 I will post the new video as soon as I can, get a better view/scenario of whats going on. Link to comment Share on other sites More sharing options...
louipaw Posted January 26, 2017 Author Share Posted January 26, 2017 Put it up on a lift and try to turn the front wheels while in park. Could be a broken short shaft ( between the axle and trans.) Ok will do! Man I'm just praying to the subaru gods it doesn't break my bank and then some lol my car won't turn the wheels if its in park even if the wheels are in the air. Im assuming you meant neutral? or maybe It does i don't recall ever trying that. In the video I'm uploading to youtube so i can link here i have the car jacked up with all wheels in the air and in Drive, the left driver side wheel and axle is barely able to keep up with the other side front passenger you will see what i mean when i put the video up the clunking noise is coming from in between the axle (cv joint/boot side) to where it connects to front diff (hoping not from the inside!)

CNY_Dave Posted January 26, 2017 Share Posted January 26, 2017 The rear diff is shot? Or did that stub pop out? Link to comment Share on other sites More sharing options...

louipaw Posted January 27, 2017 Author Share Posted January 27, 2017 Part of the left axle where it enters the front diff Link to comment Share on other sites More sharing options...
louipaw Posted January 27, 2017 Author Share Posted January 27, 2017 Might be an axle but kinda sounds like a tooth got knocked off the front pinion gear. Jack it up and spin the wheels and see if anything makes noise. As I do that while car is off and on park with wheels up I don't hear a noise but it the tranny jolts like an almost up and down movememt Link to comment Share on other sites More sharing options...
CNY_Dave Posted January 27, 2017 Share Posted January 27, 2017 The jolting was definitely in the rear diff though, yes? If one rear wheel was intermittently being driven the jolting transmitted through the driveline could make the trans jump. Link to comment Share on other sites More sharing options...
louipaw Posted January 27, 2017 Author Share Posted January 27, 2017 The jolting/noise is in the front diff/tranny area, it has an up and down movement as I am manually spinning the left front wheel forward and even as I spin it backwards. The same jolting/noise occurs Link to comment Share on other sites More sharing options...
