Suspension Noise problems of the 2012 Toyota Tacoma

My vehicle has the same problem as the recall in the 2005-2011 Tacoma recall from Toyota. The subject vehicles rear suspension system contains leaf springs that are constructed of either 3 or 4 leaf springs. There is a possibility that a leaf could fracture due to stress and corrosion. This could cause damage to the fuel tank or other components. My vehicle has the damaged leaf as described in their recall although it is a 2012, and I discovered it recently hearing a noise in the rear of the vehicle.

I bought a used 2012 Toyota Tacoma with 75,000 miles on it from a dealership with the "Toyota certification. " at 86,400 miles, the truck bed started sagging, and everytime I accelerated, the suspension would make a loud thumping noise, & the back end would wiggle & vibrate. I took it into the dealership, and they said both leafsprings (under the truck bed) cracked (at the same time), but unfortunately my 2012 was not covered under the suspension recall, which covered only until the 2011 model year. Otherwise the recall would've paid for the fix. It appears faulty steel was still used in the leafsprings manufacture well into the 2012 model years. In the meantime, I had to get my truck fixed, and spent roughly $1,100 at a non-dealership mechanic. Please investigate this as there are other trucks in this same predicament.

When the vehicle is in motion the back end creaks loudly over the rear tires. This is especially noticeable at low speeds as the truck bounces over the road. When the vehicle is stationary and I am in the bed or on the tailgate, the truck bounces easily and creaks loudly over the rear tires. I had new leaf springs installed in July 2018 because that is what my mechanic diagnosed the problem to be. Now, less than a year later the same issue persists. The sound is metal is rubbing on metal, and I suspect another part of this vehicle's suspension is bad.
