Noise from Underdrive transfercase gear set (1 Viewer)

[inkpot]

I already have my LRUD gears and my HRUD are ordered. Can't wait to get them installed and tested. I am on 37s with 4.88 gears, so nearly stock final drive ratio. I am running an overbooked TRD supercharger and water/alcohol with Landtanks MAF and oversized injectors. It is a little faster than stock, but my ultimate goal is being able to tow a camper better In the mountains.
