I'm Awesome
Hi all, been trying to chase down a driveline vibration for the past couple of years now. 98 GMC 4x4 1/2 ton with a rcx 6" lift.
I get a vibration that starts at 70 mph and doesn't go away even if I go faster, I also get a vibration for 1-2 seconds when I let off the gas going 50mph and over.
I shimmed my pinion angle to match my transfer case to +- .3 deg, had the driveshaft rebalanced with new spicer u joints. The only thing that I can think of at this point is the up and down play on my slip yoke, thinking maybe the bushing is worn, the seal is leaking also. Do I need a longer slip yoke due to the truck being lifted to ensure proper spline engagement?
Any input at this point is greatly appreciated.
