    Gettin' a deep Hum from the driveshat (?) starts at 60-65 goes away at 75 or so.....

    New Ujoints both ends
    Changed Motor mounts
    changed tranny mount

    been fighting this since it started about 4 months ago...I have had this same lift and drivetrain set up for about 5 years...this freakin' Hum just started about 4 months ago...pretty sure it's the DS since it goes away when I let off the gas....There is No vibration to be felt, just the deep Hum....Thinkin' I'm gonna replace the dang driveshaft...pretty sure I have it phased correctly using Brute Force joints (for the last 5 yrs)....haven't banged or bumped it that I know of, doesn't seem to have any marks or missing weights....Where is a good place to get an "upgraded" DS, running stock TBI/built 700r/241 and 12B... /forums/images/graemlins/ears.gif

    www.highangledriveline.com sells a nice CV slip yolk unit, but you might have to adjust pinion angle to go with the CV joint.
