So I got sub-frame connectors installed on my car and since then I hear a loud, metal creaking sound everytime
a person sits or gets off the car.
My question is if this is a normal thing, a case of cheap product, or something bad?

XD
No fat chicks allowed in the car, and I myself weigh less than 150lbs.
Any slight weight causes the creak and at first I assumed it was the conversion from uni-body
that caused the new friction but if anyone knows different please let me know*

How were they installed? Fully welded in? Also were they welded in with the car on a drive on rack or in a garage on jack stands?

We need much more context other than "is this bad?", or "creaking."

Was the car ever in a collision? Is this in the front or back of the car? You are describing a noise occurring from ride height changes, so I'll guess the front.



IF the SFC's were installed properly, they provide rigidity to the frame structure, which forces the suspension components to do their job. So weaknesses in suspension components will now reveal themselves. Normal culprits are Sway Bar end links, improperly seated springs, bad struts, strut mounts or strut attachment points, or even cracked frame at steering box.

If they're bolt-in, they're a joke.

Verify that the chassis is STRAIGHT (as an example, mine were installed on a race car jig), then weld them in. That largely cures the joke.

Sounds like the car was not on the chassis when they were welded in

The car needed to be sitting on the tires when the SFC's were installed. Was it?

Have somebody stand by the car and listen to where the noise is coming from.

Check to see if all of the k member bolts are tight.

Doesn't matter if the car is "sitting on the suspension" when SFCs are installed.

What matters is that the car is STRAIGHT. Not in a tweeeek of ANY sort: not lifted by 4 random points, not on uneven ground, not lifted on one side while sitting on the ground on the other, not not not not not not.

STRAIGHT. With the BODY plumb, square, and level. That's all that matters. "Suspension" is TOTALLY UNRELATED to them. It doesn't even have to be present, let alone in effect.

As said, mine were done with the body - minus suspension, engine, interior, and abuncha other stuff... it was part of a larger project being done at the same time - bolted down on a race car jig. Securing the body to a frame straightening fixture and trammed straight would work well also.

Ignore the myths about "suspension loaded". That isn't true.

Was the car ever lowered?
