I'm trying to explain why my FJ sags driver side after swapping shocks (kept the OEM springs). A person just informed me of the stiffer driver side spring ... and I'm trying to confirm and learn how to figure out if indeed the dealer swaped sides on me. Anyone have personal experience with OEM front springs on an FJC? Specifically, the Off-Road Package and whether the driver vs passenger springs are actually different (they have different Toyota part numbers and different color codes). Thanks!!
