Good Morning!!!! 51F @ 4:45AM. Partly cloudy early then becoming cloudy with periods of rain this afternoon. High near 60F. Winds SSE at 10 to 20 mph. Chance of rain 100%. Rainfall around a quarter of an inch.
The news was full of the storms back east last night; glad you all seem to have come through unscathed.
Hope your mom feels better for her birthday, Randy.
The way I heard noise cancelling headphones explained, Drew, was that speakers in the 'phones generate sound pressure opposite what microphones on the outside measure. Sound is a mix of waves of various frequencies, made up of higher and lower air pressure at peak and trough of the waves. So the speakers inside the 'phones reproduce the incoming waves, but with the pressures opposite of what is coming in. This neutralizes the sound. The effect can be tuned to work more effectively at certain frequencies, and to be more or less effective. So you can end up hearing things like voices, but not loud lawnmowers or firearms discharges.
I was able to get the transaxle and front differential on the van pretty close to aligned yesterday, but still have more work to do. In the process discovered what is likely excessive bearing runout on the front diff input shaft, which could be the cause of the drive line vibration. This in spite of it being "rebuilt" by the ex-mechanic. The bad bearing could also have been caused when the drive shaft was originally and improperly installed by that same person, hard to say. It's an inside day today, so I'll spend some time reading up on disassembly/reconditioning procedures, and likely get some parts on order, or find a reputable person to do the work. If it has to be sent out, very likely I'll have it upgraded with a locker, so I'll be able to get stuck even farther from the tow truck.:confused2:
Hope everyone's week gets off to a good start!
