Just installed G2 LCAs & Brackets
I just have to say two things:
- Wow what a difference! These are awesome.
- Wow, these things are loud. (over bumps)
- Wow what a difference! These are awesome.

I'll second that - under normal driving they should only be slightly louder than stock if at all. In addition to tightening with weight on the suspension, make sure you have the rod end (axle side) tight. I think mine are around 90 ft-lb.

90 ft/lbs is a good number.
But, remember, you are squeezing against metal bushings now. You can put 500 ft/lbs of torque and it will not affect a heim joint. Also, make sure the jam nuts are tight.
I'm not sure which LCAs you have ... rod/rod or rod/poly LCAs.
Rod/poly should have the poly end on the chassis and the rod end on the diff.

I have LGM poly/rod LCA's and PHR. I jacked my car up from the pumpkin of the diff. and installed them that way and then torqued them. That is the same thing as having the suspension loaded right? Mine are VERY loud as well, to the point actually that I am ready to put the stockers back on. I don't drag race anyway and I think I will get traction just fine with my nitto drags. It just doesn't seem worth it. Every bump I hit makes me cringe, I even cringe when I SEE an uneven road surface before I get to it. So what difference does it make when you torque them down with the suspension loaded or unloaded? I didn't use a torque wrench either. I just tightened them until I couldn't go any further. Should I untighten them and then torque them down again with a torque wrench just to be safe?
I was also wondering why the LCA's are adjustable? Everyone just told me to adjust them to the factory length so what's the point? I also forgot the benefit of having the rod ends... I think it was because they don't deflect/bind up under hard cornering??? Is that right? I did notice a little better cornering because now I notice my body roll. Thanks.

glitch, with all due respect, I see you complain a lot about your LCA's - what have you done to try and fix your problem? Have you checked your rod ends? Are you positive that the LCAs are the culprit (as opposed to the PHR, etc)? Its a pretty simple piece of equipment after all and there are only so many things that can be "wrong".
IMO "noise" is a funny thing since its subjective. I haven't heard the cars that are making noise with the G2 LCAs, not implying that it isn't true - just that I haven't heard it. To me mine seem pretty damn quiet for what amounts to a very direct connection to the rear axle. Maybe its all just perspective and some folks that are running heim joints and then complaining of noise ought to be using more isolating rubber bushings like the factory installed in the first place. Its pretty obvious to me (not being very smart even) that bolting a steel tube to a steel axle containing spinning gears and bouncing over the roadway with a polyurethane bushing and a heim joint WILL in fact transmit more vibration than one mounted with rubber isolators. Maybe this is just one of the tradeoffs that have to be addressed when modifying your car.
Otherwise if you have loud LCAs and a friend has the same LCAs and they're quiet then I would question the installation, tolerances, wear, etc., ya know, basic troubleshooting practice.
Just my opinion...

I'd describe my noise as: the sound you hear when walking on snow, or scrunching up a bunch of packing foam.
To make it do 'the noise', I can simply bounce the rear a little by pushing on the trunk.
I put some grease in 'em tonight, though they are supposed to be pre-greased. I'll let you know how that works out.

I had the same noises from my rear when I went over bumps, or simply moved the rear end of my car by pushing on the trunk.
It turned out to be the rod end on my PHR. Do you have an aftermarket one on your car?
FWIW, I tightened the nuts near the adjutable part of the rod end extremely tight, and that prevented the parts from moving therefore stopping the noises.

They seem to have quieted down a bit after I added grease. Each LCA took some, so maybe they didn't get greased, or not enough.... they could be settling in some too.
I've got a stock PHB (until I put the G2 PHB on that's sitting in my dining room)

I have Billingley dual rod end LCAs. They make a "clunk" sound going over a sharp bump, and a clickle-clack sound going over continuous small bumps, or gravel. I guess it is what you would expect from metal to metal contact with the driveline to the chassis?

Yeah, that's what I thought too, but you can wiggle the ball and there is no play..nice and tight. You just have to live with the fact that they are not rubber bushings, there is no way around the noise. And if you have quiet rod ends, then you aren't driving on rough enough surfaces.

Might be on to something here ...
The term "wiggle" caught my attention ...
It's all I can do to "wiggle" the bearing in the mount with my finger. Damned tight. Do you concur?
