Driver's side leaf spring help

I replaced the driver's side leaf spring centering pin and ubolts. The 1/2 block walked out of position months ago. I thought that the center pin was loose or broken due to the gap in the leaf. It was tight when I pulled it apart. I wanted to see what happened when tightening that pin back down. The nut creaked like it was rusty so I replaced it and the ubolts since I had to realign the block. Most of the creaking is gone. There was some at the rear clip so I pryed it out a hair. My concern is that there is still a gap in the spring.

 

They look worn to me, should be slight arch up or flat. These are kind of W shaped, higher in middle at axle and lower on ends.

Here are some quick shots of mine for reference. 2016 w 53k miles. Maybe 50 lbs in the bed. Hopefully others will chime in. Has the rear on yours lost any height?

 

How would they be worn at 13K miles?

 

They should not be at those low miles. Do the springs have the clamps on each end? Done much off road flexing? Is ride height in rear the same as always?

 

Yes the clamps are there, no offroading, and only 2 inch lift in the rear.

 

Can you pull the blocks, put the factory u bolts back and take it in for warranty?

 

I would have to pull the shackles too....not sure I want to tackle that job again lol.

 

If you google what causes gaps between leaf spring, it appears to be quite common. My next plan is to email some suspension shops I guess to what the consensus is.

 

Yeah those leafs look worn mine have 110k km on them with towing of a camper off roading with 1.5” shackle in the rear this is what mine look like....

 

How would mine be worn at 13K miles? The passenger side doesn't have a gap. I'm sitting on Toytec shackles at 1.5 along with the 1/2 block. Is there a spring pack that will give a 1 inch lift if I remove the block and that will work with the shackles at 1.5?

 

OP, yeah I have no idea why they are like that or look that way already.... the tundra leafs are soft in the first place which isn’t great but like Colorado TJ said have you ever overloaded the bed or carry heavy loads often?

also as for a 1” leaf pack no clue I only know of aftermarket ones being 1.5” or more I’m ordering a new leaf packs when I get my truck back on Monday lol

 

Nope. Only a few bags of concrete from Lowes. It just weird that the gap is only on that side.

 

Unless you’re missing the band that holds it together if you know what I’m talking about?

 

The front and rear where the isolators are? They are both there.

 

No I don't.

 

Yeah those springs are shot. Tundra leaf springs are super long and don’t have much arch in them to begin with. Any sort of block... even that piddly thing you messed with obviously will ruin them. Shackles will do it too.... every keeps telling me I’m crazy but I see it constantly.

 

How does it happen on only one side though? Alot of guys have Toytec or Coachbuilder shackles and don't have issues like this.

 

My theory is that because the block moved out from underneath the leaf springs were no longer solidly sitting on the axle perch allowing it to see-saw in a way that when the truck flexed or just cycled the suspension it was more than it could handle and therefore bending the top leaf and giving it more arch. Imagine the axle going down (away from the frame) and then the leaf spring begin to see-saw (pointing downwards) and the top leaf is hanging on for dear life at the shackles.

 

You need to clamp them together tighter and then tighten nut on center pin under bump stop, rough torque spec between 80 &100 '#, look up your set up for true spec
