I have a 2012 FJ 4X4 with a manual transmission. Prior to moving to Arizona, I lived in Colorado where I used my 2000 4X4 Tacoma for all of my off road driving and driving in snow. I didn't start driving the Cruiser as a regular vehicle until we moved to AZ. I don't live in the AZ mountains so driving in snow is not likely unless I make a trip to a higher elevation, which I did last week.
A few days ago, I had my first opportunity to drive on a snow packed paved road with a couple of inches of snow. I was in two-wheel drive. On several occasions, I would hear, mostly hear, a vibrating sound coming from the front. It could have been the rear but it sounded like the front. There was no steering wheel shaking or front end movement other than straight ahead driving. My tires are in very good condition. The sound would last a few seconds then disappear then return sometime later and again for a few seconds then disappear. I didn't see any lights on the dash but then, I had to keep my eyes on the road so I may have missed something.
Can someone explain what this is?
Just the other day, I learned what A-Trac does. I find the manual a bit confusing. On page 170, it addresses vehicles with two-wheel drive only. I need some explanation about A-Trac and the Auto LSD system. Again, the manual addresses Auto LSD but only for two-wheel models.
