Ita a manual trans Accord

Vibrations during light acceleration can be cause by the inner CV joints due to lack of lubrications or wear. Check if the boots are torn and look out for sings of grease spilled aroud the area. Hold the axle shaft and shake it in up/donw motion andnote if the shaft moves more than the inner CV joint. Turn the shaft and test with different position.

Did you check both side of CV shaft and boots? Turning left usually is due to right side having problem.

We can't help to locate the source of the noise and depending on the noise, it can sometimes be difficult to locate even if we have the vehicle.

You need to try to simulate the condition, note when it occurs, exact noise type and under what conditions. From there you would get an idea what possible causes are or at least eliminate those not likely to be causes.

There is an equipment called "Chassis Ear" which is a sound detector and has a few microphones where you can place them on suspected area to monitor. Some shops loan out these and you can check if any around your area deos it.

If the left shaft have failed even without the boots tearing, the right might be almost there too.

If the noise is from outer joint it would be easier to test.
Get a large open space where you can make turns easily.
Start engine and engage gears.
Turn steering to full left and while holding steering position, accelerate abruptly and release pedal. Do not go full throttle as the engine noise might be too loud to hear anything. Repeat test a few times and each time when you accelerate, that is the time the noise should come out if it is the CV joint.

For a CV joint that is not really bad, you might not have any noise at all turning angles so with steering back off slightly from full lock position, repeat test. Repeat again with various turning angles.

Btw if the replacement CV axle is a rebuilt, take note too, it might be the cause.
