I have 2011 Tundra SR5 Leveled and recently my right side rack and pinion seal blew and threw fluid all over the right wheel well and parts. I have since replaced the Rack and pinion. Now my 4hi light is blinking ant the TPMS shows low air. The TPMS came on after the oil flung everywhere. 4 hi Blinking happened after replacement of rack. None of my others lights are flashing though. Truck is in 2wd and there are no strange sounds or vibrations. Also the 4wd does not engage when switching from 2wd to 4hi or 4 lo. So is this an ABS issue. Please any help would be great.
