Little bit of a back story here. 04 LJ,Zone 3 in lift, 33's, 4:88 gears, all 8 adjustable arms, adjustable track bars front and rear, rebuilt transfer case, front and rear axels completely rebuilt, SYI, its basically a brand new jeep with the exception of the motor.
I have "THE VIBRATION" harmonic above 69 mph. Pull the front shaft and it is gone. I have replaced the front shaft with a rebuilt stock, two Tom Wood's and I currently have a Denny's drive line shaft in it. This shaft has been the best, the front pinion is .5 above the driveshaft, I have tried it in a million different angles and no change.
I put the jeep up on stands yesterday and ran it in 4x4 at idle and I can see that the front shaft has a decent amount of runout at the end that attaches to the transfer case. The shaft was high speed balanced so I can't believe it's the shaft. I am thinking the front yoke onbthe transfer case has excessive runout?
Has anyone experienced this? The jeep was bone stock when I bought it and has absolutely no sign it ever left the pavement.
