I have a vibration problem after installing a new suspension and tires (details below) on a 2007 doublecab PreRunner (TRD Offroad).
There is a vibration --felt through the seat/floor, not the steering column -- at 0-45 mph. An alignment didn't help. Can anyone help me troubleshoot the problem?
Front suspension: 4" Camburg spindles with Icon coilovers (set at 0.5") and Icon UCAs
Rear suspension: All Pro 3" leaf springs with 2.0 Fox Shox piggybacks.
Tires: Nitto Terra Grappler A/T, 285/75R16.
Alignment specifications (Left, Right) in degrees
Caster: 3.3, 3.7
Camber: 0.7, 0.2
Toe: 0.05, 0.05 (0.10 total)
I suspect that it's a vibration from the driveshaft. I've seen recommendations for a carrier bearing drop to correct the drive line angles, but it seems like a carrier bearing drop would make the angle worse for a spindle lift (not better, as in a drop bracket lift).
Any suggestions on causes and cures, and how to troubleshoot them?
Has anyone with a spindle lift experienced this?
I've only put 50 miles on it. Should I wait until the suspension has "settled in" before getting too worried?
Thanks for your help.
