Rear driver side suspension sitting 1" lower than passenger side

[Mr.volleyball13]

Owned my gladiator for just over a month now and notice my driver side rear suspension is sitting an inch lower than the passenger side. Both front driver and passenger sides are equal. The road to fend is 19 1/8" on driver side and 40 1/8 on the passenger side. Anyone else have this issue? Warranty item if the spring is sagging after a month. I have not towed and used the bed for anything cargo. I did measure the distance between the bump top and the stop plate and it is off an inch as well. Visually I can see the rear sitting lower compared to the front and it annoys me, not sure I can deal with it.

A lot of the models have different part numbers for springs on each corner. What are your part numbers?

Rear driverside =6850 6257Ab
Rear passenger = 6850 6258Ab

Are the rear spring part numbers correct?

I did check the ride high when I first bought it as I wanted to see if it was actually taller than rubicon, it was over 40 5/8 or so from road to fender from what I remeber.

Maybe it is an issue up front that is translating to the rear? I have no idea what spring numbers it should have, just that a lot of them are different. I think it is more likely to have different springs in the front.

Is the front off by the same amount?

Just curious, you should check if there is a difference when the fuel tank is low on fuel compared to full.

If you don't want to go to a dealer, I'd swap the springs and see if that fixes it. The reason springs are different is the fuel tank is not centered. Maybe your springs were installed on the wrong sides?

The front driver side and passenger side are equal. I when by a local dealership and took measurements of the two mojave's they had. Both rear road to fender where aroind 40.25". Confirming that my driverside had sagged for some reason over an inch. Got it booked for Wednesday, however, I'm sure they will tell me it's normal. An inch of seg after a month of driving

I have checked at all levels, full, half abd empty and this inch of difference is still there. I was hoping it was just weight transfer issue with the fuel tank, not it appears the amount of gas does not dramatically change the spread drivers side riding height.

That's actually a good question. I will look into the spring part numbers to see if that is the issue.

Have you checked for a shock leak, or missing bolts in the suspension?

 

[Lunentucker]

Make sure you haven't lost a sway bar link bolt. Mine lost the driver's side link bolt at the frame. Not sure that'd make it drop or not but it's worth a look.

I was thumbing through the manual the other day and found this interesting.

ive wondered about suspension sag for a while and this has me thinking.

I did not. I will check that tomorrow.

Did you ever figure this out? I noticed mine was the same today. Driver side rear is 1 inch lower then the passenger side. Completely stock at the moment.

Don't measure from ground, measure from center of wheel to fender flare. That gets rid of tire differences and other factors. Make sure it's measured on a FLAT surface, maybe a parking lot or gas station lot - many times those are quite level.

Measure like this and then tires won't matter - you can compare any Rubicon to any other Rubicon, any Sport to any other Sport, any Overland to any other Overland regardless of tire swaps, air pressure in said tires, etc. - you are comparing only suspension this way.

Sway bars won't matter. If one link breaks it's the same as if the whole thing is disconnected except the bar will still move with the one side that's still connected. but it won't impact height.
Shocks should not matter except for a tiny bit - they are filled with compressed gas but it shouldn't make a 1" difference. If one lost its charge it should make a very minimal difference.
It's difficult to see how the front can be even and the back not even. If you raise up the right rear, just for example, it should settle the left front a bit. It's how we used to deal with setting things like torque links in the AMX - raise the left front, the right rear settles and you lock the torque link in place at a certain height. Otherwise it was near impossible to load the car enough to get it to sag that badly. So for one end to be perfectly level and the other not means there's flexing going on or the surface it's on is uneven letting one side of the suspension droop while the other side is supported.

Anyway, I found using the below measurement method, I could compare my JT's "lift" with any Overland on any dealer lot even if tires had been swapped because I'm measuring only suspension height (springs only), not total truck height (which relies on tires, too)
