Power steering on '08 Taco

[kylemob]

Owned for about 10 months and took it to the mountains to hit some trails for the first time. Gave the 4x4 a good test, and spun some cookies in some nice soft mud for a bit (I'm not usually hard on my vehicles but thought I'd see what she could do). Immediately began having power steering issues. Turning the wheel all the way any direction makes the PS start whailing, and turning the wheel at a stop takes a lot of strength. No clue what has happened but I'm going to pay the dealer a visit. Anyone else had this issue or know what the problem may be? I haven't cleaned off the pickup yet, could I have managed to throw some mud up under the truck to cause the problem with the PS? Thanks ahead of time.
