funny rumble

[RoyBatty]

Does the noise at idle change if you depress and release the clutch?

may I ask what the answer would have been had original poster said yes to that question

I was along asking this to see if the input shaft/bearing was making noise. Or possibly something in the clutch, pressure plate, throw out bearing assembly.

I'm thinking I may have worn crank bearing(s) resulting in vibration I can feel in the shift knob. Its not too bad yet but I'm going to keep an ear on it.

I am wondering if crank bearings can be changed via the oil pan without pulling the engine. Has anybody attempted this??
