My driver side rear end is lower than the other side...any advise on how to fix it?

Hey guys
Just like the title said, my left rear end is like haft of an inch lower than the right, what did I do wrong? And how do I fix this issue? I can see it from standing in the back of my car and I just can't stop thinking about it. Could it be the spring or the shock that caused this issue ? What do you guys think?
Thank you

What did you do?

The shock won't cause a height issue. Did you change the springs?

Well, by your sig you have the cheapo SR springs so I would imagine it's a bad spring.

As stated above, the shocks have no affect on ride height.

If the shock is blown it definitely will. I've played with this topic with my last project vehicle. Going from gas charged to hydraulic drag shocks was worth a 1/4" drop up front. Push a gas shock in...it pushes back. Hydro shock...it stays put. I'm betting his seals are blown in that shock.

Before that, I didn't think it would affect ride height either. Also found one older internet article from Monroe that verified this.

If the car is at a standstill it's not the shock, it's the spring. The shock does not have the strength to resist the car's weight, it is only used to dampen the reflex of the spring.

I'm with others, it's the spring. Either bad or seated incorrectly.

IDK what the OP's car has or if he has a spring problem but I'm gonna agree with Intense and the gas/hyd bit making a differance.

2012 V6 traded in for a 2017 VW GTI.

I'll agree with that. Thanks Intense.

The shock will only make a small difference. My observation was a 1/4" putting hydraulic drag shocks up front on another vehicle owned. Now, I'm thinking if you rode around with a blown shock long enough, you might make the springs work harder to maintain ride height and weaken it a little. So, maybe that might end up at 1/2".

Do some googling. It's out there. I know these shocks take some ass to push in, been there. I can also go out and lift up the body on one corner out back a 1/4". It's the springs job to maintain ride height, but the compressed gas shocks do hold a small amount of load on their own. It could be a combination of a weak spring and blown shock. Just a possibility based on experience and reading other conversations.

I've noticed something similar on my car. Bone stock suspension here. Only thing ever done to it was replacing sway bar end links under warranty. Even before that I noticed it. I can see it and I measured from the ground to the top of the wheel well.. it came out to a little under half inch below the passenger side ...

My pickup was like this so I guess I brushed it off as normal. Now im worried.

At first I was thinking that it was my springs because when I first installed them, I can see the the rear driver side is a little lower than the other side to begin with. And now my left rear end sacked. A few months ago I decided to replace my rear passenger side shock thinking that it was bad due to a bouncy ride. And A month ago I took my rear suspension apart to fix my rear end clunk and found out that the driver side shock was also going bad( I pushed it down and it does not want to come back up) and that might cause it to sack even more. I don't know why koni shocks went bad so fast, could it be a combination of a bad spring and a bad shock??? What should I do? I don't really want to just throw parts at it just to find out what is wrong with the car.
Thank you

Another possibility for a small difference could be if a component such as a control arm on one side was replaced and torqued with the suspension hanging. It would be a very small difference but just throwing it out there.

I'm not sure. Potholes or rough roads? Bad batch of shocks? How many miles were on them when they blew?
