Why would my passenger side lean an inch?

I noticed it within 2 months of getting new springs. Is that really possible with less than 500 miles on a set of new springs?

It’s not even a constant load. Sounds crazy to me, but maybe I’m out to lunch.
Yep, same here sadly. It happened rather quickly after I did the Rancho 3" springs
 
I have heard this "torque lean" before, but why only in lifted TJs, and why would the torque go only to the passenger side rear tire? I do not understand that part.

@mrblaine any credence at all to this theory whatsoever?
Not sure, dont quote me lol. I just remember reading that it goes to the passenger rear.
 
Nope. As mentioned....Rubicon Express springs. Same ones I've had on forever. The effects of torque from engine acceleration over time? Causing sagging of the passenger side springs?

I'm probably one of the least qualified to reply, but I noticed that your original post and this one mentioned that the springs are the "same old". So surely it's just time to replace, because they are sagging over time?

As for why the springs would sag more on one side than the other over time, maybe that's what you're really asking. Your theory about the torque seems to be supported by some comments on this thread.

Maybe it's something I'll never have to worry about with my 2.5! ;-)

All we have to do to check for sag is measure the springs on all 4 corners. I already did that on my months old RockJock Springs and they’re virtually the same. I measured at the axle tubes and they were identical. CA’s were torqued on the ground under load. Baffling.
 
I've noticed that the TJ leans a little on the passenger side.
Park Jeep on wrong side of road or nose facing out driveway if you pull in nose first and re-measure. My jeep always leans but it's because of the road pitching for drainage.
 
a 1/4" difference in the pavement under 1 corner can make mine look like its not level and i have completely different suspension than y'all do,

most hard surfaces are not flat they are made so water cannot sit and puddle by means of crowns or angles/tilts.
 
I've noticed that the TJ leans a little on the passenger side for a while. Before I had some recent suspension work done. It wasn't until recently when I had the tire carrier open that I noticed it to the extreme.

I measured it with everything in its place. Tire carrier closed. 3/4 tank full. My wife not in the passenger seat. 😕 It dips about an inch on the passenger side. New shocks. New control arms. Newer front end. Same old RE springs.

What could be causing it to lean on the passenger side? I'm making the assumption that I don't have a crappy MC uneven spring situation.
Swap springs side to side and see what happens.

Not passenger side, right side rear corner. Left front always lifts under acceleration and pushes down on the right rear. Follow a lifted TJ down the highway that is running into a head wind, you can see them torque over.

Newton figured it out for us. For every action, there is an opposite and equal reaction. The aerodynamic inefficiency of a lifted TJ contributes to a larger than normal load on the chassis just to move down the highway at speed. The chassis is twisting diagonally from the left front through the right rear corner.

Also why they make output reversers for competition rigs to counteract the drivetrain torque and flatten the chassis out. It is rare that you see a TJ on a climb that is at the limit of what it can do for various reasons that the left front doesn't come up first.

Check your swaybars. Unhook one side of each and bounce the rig. You might also have a slightly bent shock shaft that is sticking in the body and not letting the shock extend properly. If you have adjustable swaybar links and set them dimensionally the same instead of with the body level, that can pull one side.

Torque lean can occur on any rear wheel drive vehicle. Passenger side only? Depends on which side is the driver side and what direction the engine spins.

Here we show off some left hand drive Americana!!!

i find the same guy in front of me quite often on the way home and it's crazy to watch him take off from a light, the rear right dumps and the front driver looks like it's gonna pull right off the pavement. little more engine he'd need a wheelie bar.

Any rear wheel drive car that I ever owned (mustang,camaro, chevelle etc) had some amount of lean to the passenger rear.
My last TJ had a lean to it also, until I removed the rear track bar and triangulated the rear.
My LJ is triangulated in the rear and also doesn't lean.
Could it be that the rear track bar is partially responsible?
 
It's common enough that I've replaced that spring twice over the years.
So it helped. So it is a spring sagging issue?

I had a thread a little while ago about if I should replace my RE springs as they were pretty old. The consensus there was that spring sag was a myth. Now I'm just confused....
