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.

I'm assuming these are poly ends?

If I remember correctly, white lithium grease is water soluble, and would wash off quickly. Use a petroleum based grease.

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

are you torquing them while the suspension is loaded or unloaded?

You should not use petroleum based grease on poly bushings, it will attack the poly. Use the synthetic grease I pointed to. It's waterproof, looks & feels just like the grease in the little tubes that come with poly bushings, and it's $5 for a big tube.

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've been real happy with standard moly/graphite
engine assembly lube on my suspension pieces, but
I have all rubber bushings throughout.

I have an exhaust hanger that squeaks and of course it picks and chooses when it wants to be a pain. I get out and kick the pipe and it stops for a while

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.

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 thought about taping one in but had no idea what they were called, Zerk. Ok...I do have those on the 30th.

I picked up some Prothane Super Grease and it shut up my poly ends. I cannot say how long it will last (just put it on yesterday.)

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

I use anti-seize and its held up great for years. You also have to get them TIGHT.....I think the specs are 75ftlbs. Then post some lock-tite on, let it dry overnight and they won't come loose again.

Really 75ftlbs! I had no idea the specs were that much. Going to shoot for Monday.
