Creaking lumbar area driver's seat?

[Rogue-Runner]

I went off-roading in southern Utah last weekend. It was 3 hours of washboard trails and deep, soft sand. T4R did ok except near the end I got a high transmission fluid temp warning and my shocks were hissing. All was well after a short cool-down.

But for some reason, I think all the harsh bouncing messed with my seats. Now, every time I accelerate, brake, or go over a bump, I can feel this creaking/rubbing against my lower back in the lumbar area. I can recreate it by pressing on the seat from the back. Definitely wasn't there before. Not a big deal, but I notice it constantly and it's annoying. I've messed with the lumbar support and done everything short of removing a panel to see what's going on. Anyone else ever have this issue?

T-SB-0051-12 - Driver’s Seat Popping/Creaking/Squeaking From Lumbar Area (March 1, 2012)

Some 2010 – 2011 4Runner vehicles may exhibit a condition where the driver’s side seat back lumbar area makes a pop, squeak, or creak noise while driving. The condition may become more evident when driving on rough or uneven road surfaces or while moving around in the seat, especially if the lumbar support is fully extended. Replace the front seat back spring assembly to address this condition.

popping/creaking noise on seats?
