A bit of extra driveline noise after lifting isn't considered unusual.
My "harmonic vibration" happens around thirty.
If you drop the front without doing the same in the rear, you will change the caster...or is it camber ?(always get the two confused) angle, which will have an effect on handling.
IMO, the increased CV angles after a lift have more to do with boot failure than off road excursions...unless you're wheeling over pointed sticks that will snag them.
The Mecatech boots appear to be made of a material with superior thickness & flexibility compared to stock.
Right after I lifted mine, I ordered a set of Mecatech's...I'm the type that over prepairs for things that may not even happen.
Of course I haven't needed them....hmmmmm, maybe I should buy a crate engine to prevent...naaaaa.
