You might get more responses if you post in the generation specific section. I wish I could help you figure it out...

How much did you lower it? Could it be the driveshaft making contact with the floor pan?

Is it kind of a creaking sound? Because I have a Knocking/creaking noise that is coming from my rear and I believe its from my LCA's.

If the control arms have Heim joints they should break in and stop creaking in a short time.
If you have poly bushings, the noise can be permanent if the bushings are not grease-able. Some companies ship a special silicone installation grease that counters these noises. If they are installed dry they can make quite a bit of noise and it may not go away.

ya i lubed the joints they got quieter but then came back after some driving. The noise is really annoying. Do all the aftermarket poly arms make noise? I might have to buy new ones
