Way to quiet some squeaky LCAs

Any real way to quiet some squeaky LCAs? It seems like almost every month I have to take off and relube them. I've gotten down to just spraying some white grease in the joins but only lasts a couple days. Yes I've used the energy susp grease and lasted a bit longer. I hate my vert sounding like some old ford! Yet my 30th had yet to make a noise in like 5yrs since susp was modded.
Any solutions? And no I don't have a grease fitting on the LCAs.

Yeah poly ends. Like I said its just on my vert, my 30th I greased when I put them on and never an issue. The vert gets driven daily and the turn on my driveway goes over a small rain gutter so when I turn into it the susp hits it at a odd angle. Well, I'll pop it off again and grease it again with my syn grease and try an extra turn. Thanks

Definitely stick with a synthetic grease because if you use a grease that is petroleum based it will soften up the poly-urethane bushings and create other issues. If you have used anything beside a synthetic grease in the past the bushing may be compromised and where the noise is coming from. What brand LCAs do you have? Maybe we have some replacement poly-urethane bushings that would work for you.

I don't recall the brand this min, all three cars I know are diff brands. Odd thing is on the body, left side is the noisy one.
I've tightened them both ways, loaded or jacked and I used the grease in the little tube that came with them. I hope the syn grease I've used didn't hurt them.

Quick read on greases http://www.etrailer.com/faq-grease.aspx
More in-depth dy DuPont

OP, Can you drill and tap for a grease zerk? The fittings are dirt cheap at any hardware store.
I use synthetic moly EP grease on just about everything because it repels water and stays together well. White lithium grease isn't good for much more than a squeaky door hinge IMO. The red grease is good for parts that sling a lot and take heavy load, should do well in suspension joints if compatible with your bushings.
Here's a few quick tests to see how your grease behaves.
1. Good old hand test. Put a dime size spot on your hand and rub it around to see how "sticky" it is.
2. Pour water on your hand to see how it repels water. Rub grease and water together to see if grease stays together or water penetrates it. Add another dime size spot of grease and rub water into it to see if changes.
3. Put a small blob of grease on a flat surface. Smack it with a hammer! It should stay together. Less splatter is better. Less sticking to the hammer is better.
4. Heat test. Put a fresh blob on the ground or other safe area then torch it. Pocket lighter won't get hot enough, use a propane torch.
5. Freeze test if your climate requires. Leave some in the freezer or fridge. Wait for it to get as cold as your coldest month, then do tests 1-3 with the cold grease. Some greases will separate in the cold.

I got a tube of pure silicone grease for my grease gun from grainger and have had no problems. no petroleum based grease on poly's. I also use high voltage silicone grease used on high voltage stress cones for the sway bars torque arm bushings, etc
