Passenger Side Taco Lean

So im needing some opinions on what may be causing this. If you look in the picture. The passenger side of my bed sets a lot lower than the driver side. Like over an inch. The bumper is lower as well. Ive heard if this issue on the driver side due to the gas tank and battery. But not much about the passenger side. Wondering if it could be the leaf spring, but the truck only has 40,000 miles on it. If i measure from the back corners of the frame. The passenger side is almost and inch closer to the ground. I just started noticing this and i know it wasn't like this when I installed the lift at about 15k miles. Thanks!

 

What do you have on the rear? What shocks? Looks like the right rear may have bit the dust. I know it's common among lifts and that's where adjustable coils come into play, but it's usually only a small amount of play.

 

What is your rear spring set up? The spring is the device that takes the weight of the vehicle... the shock only dampens suspension movement. You may have a spring flattening out, a bushing failure or a missing component. Compare and measure both springs, and look for differences.

 

I vote cracked leaf spring

 

Factory shocks with 2” blacks under leaf springs. I measured from the leaf pack to the frame right above the u-bolts. The passenger side is about an inch or so of a smaller gap. Took the shocks loose and still sets the same so that eliminates shocks but they pretty much just dampen anyway. Bushings look good from what i can tell and the shackles look fine. I do quit a bit of off roading so im guessing having the 2” block has caused my leaf spring to bend. Gonna order new ones. Lifted ones and hope for the best.

 

The blocks will not cause the leaves to bend offroading any more than the axle will bend the leaves. The leaves on the right side are either tired and sagging or damaged and cracked as mentioned by @GrizzledBastard

 

Look very closely at the center of the pack. Could be one of the sandwiched leafs. In my experience (I've busted a few back in the day jumping my '77 Cherokee) they fail where the locating pin is.

No more jumping!

 

Lift blocks for sure add additional leverage to the leaf pack and cause more axle wrap. That has been proven. Anywhere I've read and everyone I've talked to has said blocks are a lot harder on your leaf spring if you off road a lot. But anyway i ordered lifted leafs to get rid of the blocks. I will update once i get the old packs out and examine them closer.

 

Yes, you are correct. Blocks do add torsional stress to the leaf pack. This will create an obvious wave in your spring, from winding them up with high torque. This is force increases with block height. A 2 inch block will not be really bad unless you are hard-core wheeling in 4 low a lot. Really loading up the drivetrain and wrapping that spring. To that end, since you understand that force and result, then a proper spring pack is the best choice to lift in the rear. I personally would prefer a spring over a block over 1".
