Normally wont post for my own **** but this has been happenin for the last month or so. Its a wirring kinda noise.
Only happens under acceleration. Fine under "normal" throttle or idle or not hard acceleration. Replaced all my exhaust gaskets the other day and saw my driver side strut was covered in ****.
Was hard to tell if I blew a strut or my cv boot is ripped.
Pretty sure my cv boot is ripped from the grease everywhere but dont know if it would cause the "whirring" sound. Hoping so though cause I did not see anything rubbing anywhere.
And it doesnt really sound like its comin from the engine.

Well, if the CV boot has been out of grease for a while, it can potentially damage the CV joint, but that "usually" makes a clicking noise. Possibly a bad wheel bearing? Good way to test is get to a cruising speed and make sure there are no cars around you. For example, if your left front wheel bearing is bad, when you steer the car to the right, you will apply more load to the left wheels. Does the sound increase? When you steer left, you take load off from the left wheels. Does noise get quieter? If this happens, you most likely have a bad wheel bearing. Try this and let me know what happens

Replace axle boot first. Did it start just out of nowhere or was it after you did something?

Started happening after I went on a road trip and some really bad bumps on the highway. Again strut is covered in grease and I think its cv boot. Replaced all my exhaust gaskets two days ago. Thats when I noticed it.
Was just tryin to make sure its the cv boot and not the strut. Would make a video but unless your in the car you wouldnt hear it.

No clicking noise. Sounds like something is rubbing but nothing is rubbing.

If it's kind of like a humming/whirring sound, that's usually the sound of a bad wheel bearing. As for the CV boot, there is an inner and outer CV boot. Since its spraying on the strut, that's probably the outer CV boot. Inside the boot, there is a joint that allows the wheels to turn and still rotate. The inner boot and joint just slide in and out. You can probably replace the boot if you have the tools to do so and be okay with that. Drive your car the way I explained and let me know what you here. Don't need to accelerate. Just cruise at like 45 and turn the wheel left and right (smoothly) and see if the noise changes loudness.

The noise only really happens under acceleration. Again the strut is covered in grease. So bad boot. Replace. Better. If not really bad cause. Its not, its the boot

Well if the strut is blown, it will not be grease per say...more like oil leaking, but it could be dirt caked on it. However, I don't think a bad strut would make a whirring noise while accelerating...if severely blown, it will make more of a clunking sound when hitting bumps and imperfections on the road. Can you take a picture or something? The CV boot grease is usually either a dark brown or a dark gray color

No. My passenger side is clean as ****. There is grease all over my driver side strut and it kinda looks like its comin from the boot. But the boot itself isn't covered in grease.

If your boots not torn its not grease. Sounds like a blown strut. How many miles on struts?

If its covered with grease so should the inside of your wheel if its a torn boot. Pull the corrugated parts of the boot apart and inspect for a crack. Mines cracked and there's grease all over the inside of my tire. If there's "grease" on your strut and your axle boots not torn my money is on a blown strut and shock oil that's collected dirt and thickened up a bit.
Find source of oil or grease shouldn't be hard as there's only half a handful of things with any sort of fluid or lubricant in them.

Thats how I narrowed it down to blown strut or torn cv boot. All that grease could have only come from one of two places. Does yours make a whirring almost rubbing sound on harder acceleration? Again will post vid and pics tomorrow.
