Hey, this is my very first post.. ahh. I went off roading this weekend in my '07 FJ. I kept it pretty tame and just went through some mud and water that didn't go above my bumper. I noticed yesterday that I had a weird sound going on, almost like a winding/grinding sound. I can hear it when I idle, and when I am driving it only happens when I hit the gas. Someone said that it could be from water or mud getting on my bearings on one of my pulley systems. Is anyone else familiar with this?? My FJ has about 80KM on it. Let me know if anyone knows what this can be, and if it's something I can fix without taking it to Toyota. Thank you!!
