Hello all!My 2009 i30 1.6 crdi, has yet another problem. The left rear corner of the car was hanging about 2-3 cm. (ca. 1 inch) lower than the right side. Therefore I replaced both rear coil springs and shocks, and got the car aligned. Now the car drives smooth, straight and i can't feel anything wrong with it. After I replaced the springs and coils, the car seemed to be at even high in the rear. After about 1 week, the car started sagging again. Today I tore the whole thing apart again, nothing unusual to notice. Everything seems fine and in good working condition.If i look under the car, it is clear to see, that the left spring seems more compressed than the right one.Do you guys have any suggestions to what might by wrong?
I know. It is strange. Can it be one of the lower arms / components, who is at fault?
Springs are typically marked LH/RH.Have then been fitted to the wrong side ?
I can understand a NASCAR having a biased setup on one side for ovals.
Could the camber of the roads be causing the problem ?

I suggest moving the fat passenger from the rear of vehicle

OEM springs front have same part number, OEM springs rear have same number so not sided.Rear shocks not sided , same part number, rear mounts same number not sided macpherson struts are sided, struts mounts are not, same part numberDo you have any examples of this?

Pretty much every after market spring ive ever fitted, typically a vehicle will sit higher on the drivers side.

Okay, to clear things up a bit The car was sitting low in the rear left corner, which is the driver’s side where I live. Therefore, I inspected the suspension and found, that the left rear shock looked worn and the coil spring looked worn and compressed compared to the right one. As the parts was somewhat inexpensive and old I chose to replace them with Monroe shocks and Lesjöfors coil springs, who is a Swedish manufacturer. After the new parts settled over a week, I had the car aligned and everything was fine for about one week, then the rear left corner started to sag again. I have checked that the part numbers are correct, and both sides uses the same parts. Everything was torqued down to specs. This is very strange! If I get the chance today, i will take it all apart again.
Disassembled the whole thing again yesterday, including removing of the lower control arms.Discovered that the bushing in the hub carrier on the left side was worn a small amount and had a little more flexibility and give compared to the right one. But certainly not enough to cause a 3 cm. drop. Cleaned everything up and swapped the springs around. Same as last time, everything looked fine right after. I measured that the left side was around 3-5mm lower than the right, which is acceptable. Today I am going on a 200-mile trip. Exciting to see the results after some driving. If there is no improvement I will post some pictures for you guys.
Okay, Remove spring / pack top & bottom by 10mm/ replace spring. Measure. Drive & measure. If sag that again? ?? New car ???
