Hello Gents,
I've come for your help.
I just recently replaced my brake pads, rotors, struts and outer tie rods. During that process I was pretty liberal with the hammer to get some stubborn nuts and parts off. In particular, I beat on the outer tie rods a lot to get them to to budge, while spraying liquid wrench in the threading. The only other area I hit a little bit with a hammer was my spindle nut. I put a socket on the spindle nut and hammered it a few times to loosen some rust. I'm hoping this isn't part of the problem. After finishing those repairs I noticed a sound coming from the front of my car. I don't know exactly where though. I'm hearing a grinding sounds as my car needle passes through the 3000 RPM area. This is while the car is parked at my home. I'm trying to find out what may need to be fixed in my car.
One last thing to note. My car is running and I can drive it. I've only taken it around the block twice though since the lower ball joint is shot.
Problem 1: The grinding occurs regardless of whether or not I have my foot down on the clutch pedal when I'm revving the engine.
Problem 2: There is a separate whooshing noise I hear coming from the hood of my car. When I push my clutch down, that sound fades completely. Any help is greatly appreciated.
I've also made a quick video as a visual aid if it helps. https://www.youtube.com/watch?v=vTQlAixAdH4
Please let me know if you need additional information and I will be happy to provide it.

does the sound really coming from the engine and not in the suspensions? it can be also loose bolt from vibrating. have you already check the drive belts or pulley and bearings? when im tracing unusual noise in the engine I use a small cut of hose i put one end to my ear and the other end in my suspected areas. like a doctor with a stethoscope. sounds crazy but it works for me. just ask for someone that can step on the accelerator while checking. I think the clutch noise issue is different

Thread is actually a bit old now for advice "drjones." It's sitting still so the work done, brakes, struts and CV joints are not involved. It has been read without a response till you just came by. Please leave threads with nothing already or much over a week are done.
Original person. Bet if and only if this noise just happened from your work you may have with excessive hammering out tie rod ends done something to PS? Is fluid full? If you haven't fixed it yet or found it, try taking belt off and see if noise disappears - just quickly for a check. If the noise is gone spin pulleys and check them for anything wrong while belt is off.
Note: When you push in the clutch the trans is just sitting there as dead weight if sitting still as you were.
The vid was good but noises can be difficult if not there in person,

after reading this and reading it is a manual transmission i can almost 100% assure the sound you hear is the input shaft bearing (main shaft bearing) in the transmission, when you accelerate at lower speeds and lower rpms does the sound escalate ?
usually when your hear a noise like this and you have the clutch out it turns out to be the tob (throw out bearing) and when the clutch is in it tends to be the input shaft bearing (main shaft bearing) in the transmission but when the bearing gets that bad it can happen whether the clutch is in or out.
if so it is the input shaft bearing (main shaft bearing) in the transmission which are known to go on the 7th generation civics as well as the head gaskets.

Re-opened upon request of OP.
Note: These noises if I read this correctly happened immediatly after brakes and front end work. The noise does this sitting still so forget brakes, CV joints, struts as they aren't involved! They are not in use when this sudden noise issue happened. The hammering hard (so it seems as said) on an outer tie rod end seems to me the most likely cause possibly shocking rack and pinion steering which is ready with PS pump pressure to work even sitting still revving engine.
Maybe just in hoisting to do this something weak let go? Do wild cooincedences happen - sure do. Again the high liklihood is something done with the work bothered something else or even damaged it. It has to be something that moves. IDK - if copious sprays to free stuck parts got on the belt could even be part of it or all of it. That's why I suggested trying it with belt removed for a test.
Thoughts include hoisting improperly? IDK - envisioning a jack, and jack stand and need to know where to place things while doing this work. That is why I think that could be involved. Was oil pan used to support this by mistake or something? We don't know yet. Let OP come back with more info on how that work went and what was done. He already said took hard hammering. I'm just groping for clues why this instantly happened, - T

I appreciate all the input. I will definitely come back with more information this weekend when I get a chance to tinker. To give you more input on the hoisting, I had a hydraulic jack and a 3 ton jack stand. I used the side lining of the car just outside the reinforced area to pump the jack so that I could rest the reinforced area on the jack stand. The non-reinforced metal was dug into about 1/4" but it was superficial damage only.
As for this weekend, I will try removing the belt to see if it has any effect.
I will be replacing my front wheel bearings and the other front ball joint. Hopefully, I can diagnose these noises while I'm in there.
I will keep you guys posted.

Notes: Hoisting takes knowing where to AND if rusted what alternate spots. This is going to vary car to car. Many oil pans look at a glance like they would be strong enough - NOT. Always consider the surface you are working on. Concrete is generally the best. Asphalt in the heat especially can fail. Use of good quality thick plywood can be fine. Basically use your judgment on the situation in front of you or seek help. Too many people get hurt or killed for what could be prevented.
Jack stands - solid ones only. The stamped steel ones I don't trust. Unsure of ratings listed for all these things too. Double up if unsure of any places.
With wheel bearings you can feel them in hand if OK or not. May be on my own opinion and experience but would only replace ONE bad one and leave the other side alone. Too many cheap new ones will not outlast a good original. Hub type (most now) bearings are not visible to see tell tale early failure I'll call galling which is tiny pits in anything that needs to be perfect. A good bearing makes no sound when spun and no feel of freeplay.
I've had assorted bearings last an hour, day or forever. Many OE assorted throughout vehicle can last full life of vehicle. IMO, #1 reason for failure is being submerged in water or moisture gets/dirt get in + in or many Chinese bearing just aren't good with quality control + bad from the get go,

Hey Tom,
I took your advice on the wheel bearing repair and replaced just the front right one that was shot. I also took a closer look to see if there was any serious damage under the car from the jack/jack stands, but it looked fine. I ran out of time during repairs and didn't get a chance to mess with the belts, but I did get a nice sunburn.
My car finally seems drivable and is very quiet when in gear. I created a video of the repair to hopefully help other DIYers with wheel bearings. https://www.youtube.com/watch?v=RZQMm-iByvQ
I will have an update on the noises next weekend when I dive back in.
Best Regards,
Sean

Didn't re-read whole thread but sounds good. As said I do 'generally' approve of just replacing the bad bearing only as quality of a new one and life expectancy is uncertain to me. If all quiet and feeling good now I'd consider this done. Do suggest a good alignment if not already done,
