I still have noises coming from what sounds like the GC kit. I just got back from lifting the car up and without any weight on the suspension I can grab the spring and move it back and forth REALLY easy. I may be wrong, but it seems to me like that when I go over bumps, brake, let off brake that the spring MAY move and make these noises. Cause it is just metal to metal. Maybe I need to do some adjusting? I have the Nitto 255/45/18's on it. It is 27.5" in the rear and like 26-7/8" in the front. I have the spacers on the rear. If anybody can help, it would be much appreciated. Leaving in the morning for Indiana and I would love not to listen to that all the way there. Thanks.
The springs are suppose to be easily moved in their perch with the suspension unloaded. That's not the cause of your noise. You'll need to give us a refresher of what noises you're getting with the GC...
Over bumps and at a start and stop, it sounds like a clunk. I have that RMD bar on and all that looks really tight. I just put the spacer in today with the rubber washer. It still makes noise. I'm driving around with the entire back seat out. It's not gremlins I swear. My buddy was in the back seat the other night and he was like what is that noise?
crank the nut on the top down as hard as you can and make sure that rubber bushing is totally! compressed. aka smashed aka smushed out. otherwise you will get clunk
Sometimes when you jack the car up, a rear spring will not seat properly in the perch when you lower it back down. When you then drive off and go over any small bump, that spring will reseat in the perch with a BAM !!! Scared the crap out of me the first time it happened.
double check the center shock bolt at the top... mine came off when driving 3 days after install (talking rear here) and made a huge bang.. but if you are getting noises i'd say you need to add the spacers in the like feffman found out for us... i have ZERO issues with my GC and i love it.. (except for the front squeeking, even with the $33 bearing per side in the front BIGGEST WASTE OF MONEY!!!)
The more i read about the GC kit the less i want to take the plunge..so many mixed results
Has anyone installed the GC kit and retained the stock ride noise quality?(minus, those creaky ass TSB Spacers, now those were a waste of time) I just keep on hearing about bad results from this route and prolonged mod hell..
The only issue I had was a squeaky driver's side bump stop. A bit of greasing a few times over a few months and I don't hear it anymore. Other than that, I've been very happy with the GC...
I am still on the fence about Ground Control because I will need a new set of shocks at the same time.
Whether I get replacement FG2s, QA1s or anything else + Ground Control, + the other bits & pieces required to make GC quiet I get a cost roughly equal to a set of KW Coilovers that reportedly have no issues.
What exactly is the Feffman fix? Are they the bearings for the fronts? I am in need of a suspension overhaul. I really don't want to go into another mod hell as my sway bars are my nemisis right now.
The bearings dont work! it still squeeks.. i bought the $33 each bearing and it squeeks, but to all on the fence... jump on over! do the Feffman fix in the back and the back will be fine... in the front if you want to do the bearings dont get the sealed ones for $66 just do unsealed ones... i can get 2 of them for about $25 lol...
as we all can see some people cant stand a click of creek, where i will deal with a fcking squeek for the great handling.... PUSH THE THROTTLE DOWN AND YOU WONT HEAR THE SQUEEK!!! lol
Well. I raised the ride height (now it looks raked out)HA. I took the strut bar out. Tighten all of it back down. Made sure to smash the center pillow with tightening of the center nut. AND I STILL HAVE THE NOISE. It's killin me. I don't know where else to look. Maybe I got a bad fg2. They were brand new? Can I throw on my original shocks and test? Are there any bushings back there that could be bad?
Are you using 2 spacers as suggested by TBJIS? If your are I would try 3, the symptoms still sound like the shock, not the spring.
The bushings in the rear are within the control arms - they usually get "squeaky" but would not "clunk" unless they are pretty far gone. The bushings are not serviceable and require the replacement of the control arm.
There's nothing there showing me anything wrong. If you've got a friend handy, I'd put him in the back and just try to listen closely to see where that noise is coming from. Maybe using a stethoscope?
In fact, the predicate for the Feffman break through was the realization that the short GC spring with its gap when the suspension is unloaded was only a "decoy" and the problem had to be elsewhere.
I've had some Squeaking/Clunking issues after jacking the car up, or after some rainy days. Usually Jacking it up, moving the spring around, and spraying some White Lithium Grease on the Upper, and Lower parts of the seat - and Whala!
There is a guy on the 09 forum that put in some Eibachs and had some squeaking coming from the front, so he wrapped the coils with rubber hose. I guess it eliminated the metal on metal noises.
Other than that, the randomness of this happening to some people and not to others is probably the most annoying part of this. I haven't taken my suspension apart to put springs in, but might there have been a bushing or washer on one of the suspension parts (sways/toe-rods) that you forgot to put back on.
Anywhere I see metal to metal, I'm thinking sandwich some rubber in there. The only thing is the adjuster may not spin as easy with a piece of rubber between it and the spring. I'm not to concerned about adjusting on the fly anyway. I might rap that sleeve to. McMaster has everything. They have those throw out bearings for like a couple of bucks (unsealed kind).
Justin: Please take some pics of the top of your rear shock mounts showing how the rubber is compressed and the spacers are installed. I'm guessing you clunk in the rear has to do with that area. Did you tighten the top bolts after the car was back on the ground or when the suspension was still unloaded? Do you have the thin rubber washer between the shock's dustboot and the mount? Did you consider modifying the internal metal sleeve inside the mounts instead of/ in addition to adding the Feffman washers?
