Possibly sagged one rear spring

Hello!

I have noticed a strange issue on my Jimny recently.

The space between the top of my rear right wheel and the wheel arch above it is significantly smaller than the same space between the rear left wheel and the wheel arch above it.
That was not the case a month before, as I usually look into those details from time to time.

The height of the empty space above my right rear wheel is 9 cm, where the height of the same space above my left rear wheel is 11 cm. I took those measurements on a flat level parking lot, with no significant load in the car, and the fuel tank was half full.


Questions:

1. Any ideas on the cause?
2. Could it be that my right rear spring has sagged?
3. Is it common for just one spring to sag?
4. How could I measure or test if the spring has sagged?
5. What else could it be, if the spring is not the cause?
6. If the spring is sagged, is it a serious issue (can it lead to further chassis, suspension or drivetrain damage if I don't fix it soon)?
7. Should I replace both rear springs together?

yes I noticed this when I took my OEM springs off
the short rear springs look at the right one :blink:



thinks it's down to single RHD vehicle occupancy and fuel tank - more weight

Might be structural failure so an inspection is first port of call with the car up on axle stands. If all looks well and the spring is not broken then a sticking damper can cause uneven ride height. If they are ok(try disconnecting the lower bolt and exercising them fully In and out) then its time to suspect the spring(s). It is recommended to replace any suspension component in pairs across an axle for safety reasons.

Check the rear shock brackets on the body

My damper and shock brackets were fine

can only think it must be down to the right spring compressing when accelerating on right lock to overtake slow moving traffic

or - when going over speed bumps, do you run the nearside wheel in the gutter so only the offside hits the bump ? as that is the best the way to take the bumps in a JImny rather than crashing both wheels over.

i just troubleshot the same/similar issue with my jimny, here's what i did & found;

- reseated all the springs, they'd twisted about half a turn & weren't correctly located in the bottom spring locators, causing them to all raise the car different heights

- found one of my front shock mounts were broken, had to straighten it & weld it, don't think it actually corrected any issues

- main issue was my sway bar was bent & twisted quite badly (due to a failed mod i did), removed that & it's now pretty much perfect
