One side higher after add a leafs

I installed a set of pro comp add a leafs today and when I wrapped it all up I noticed one side was sitting higher than the other. Any tips on what I could've possibly done wrong?

 

Did you tighten everything down with the truck on the jacks? It might be bound up if you did. Needs to be on all fours under its own weight, then snub 'er up.

 

So should I loosen up the U bolts and then tighten them down? As its sitting on all 4's

 

Wouldn't be the u-bolts as much as the shackles/bushings. They're the ones that move. You could loosen 'em up, jump up up and down on the bumper a bit, then tighten / torque again. Worth a shot.

I'm not familiar with the pro comps but another possibility is the leafs got stacked out of order if they came loose but I doubt that - most are different lengths so it's hard to mess that up.

 

I should have asked which side is higher and how much? Tacos have a tendency to sit higher on the passenger side due to the location of the fuel tank on the driver's side.

 

I have the same issue on my truck. Pro comp aal in the rear now the drivers side is an inch higher.

 

The passenger side sits higher and it's about an inch

 

I'm not sure how the shackles being loosened and re tightened would do anything. The install process of the aal does not require loosening the shackles.

 

Yea I didn't loosen the shackles, just the center pin and U bolts

 

Guess I missed that whole AAL piece. Too much sun and beer today. Carry on and good luck!

 

Probably it always had the "Tacoma lean" just didn't notice until now. Usually it's lower on the driver side though? Do you see any gaps between the AAL and the OEM springs, like they are not seated right? If it's a 2010 or previous does it have the 3 leaf pack? They fail! Even with AAL the OEM leafs still failed on mine. Are the OEM leafs bent?

Off the top of my head that's all I can think of.
