Rear leaf springs replaced again

I had the TSB rear leafs done in 2012/13. Today did frame inspection, passed and spray will be done in March. Tech noticed I had a broken leaf spring, Toyota replaced both my leafs again ZERO charge. Nice to have new rears at 164,000 miles. A few times I have hauled 1600lbs and a couple of times a ton load of coal in the bed.

 

The broken leaf was a part of another TSB since it caused a safety issue since the broken leaf may puncture the fuel tank. The new leaf pack has an additional leaf spring clamp

 

Im at 175k on my 05 havent done TSB replacement talked to few people that did and didn't like starts to sag. I guess depends on usage of with your truck I never really haul heavy loads. May hold off until after shocks replacement.
