Have a 98 5.9, stock suspension (and worn).. 206k on the clock.
Recently disconnected front driveshaft, new (to me) rims and tires ( when I bought the jeep it had some old snowflakes on it, found some decent tires on stock limited rims on CL and swapped them), new u joints on rear prop shaft (match marked, installed correctly). The jeep handles ok, needs shocks badly, stock ones still there, waiting on blisteins from Kolack, among other things.
So my problem... Very hard to create. Must be going up a slight grade, rpms at 1400, around 40ish mph. Get a vibe that feels a little less harsh than the washboard on the side of the interstate. It also sounds like you are driving over the washboard. Any throttle change and it's gone. I'm stumped.
