Default Supension squeak

So, as I said in other posts, since I removed the very stiff Bilstein front shocks and now that my suspension is actually able to move, it of course is squeaking, badly.

Most if not all the bushings ( probably all according to the previous owner that replaced them), are poly.

I've sprayed lubricant on them, usually silicone and nothing seems to be helping. What bushings usually cause the squeaking, is it mainly the upper control arm bushings?

If I push down on the top of the fenders or say when going over a speed bump I hear it the most.

Do I need to take the arm apart and grease the bushings themselves?

any recommendations on a better lubricant I could spray on them? I've read some say Superlube works good?

Is it possible that you are hearing one of your ball joints squeak? I had a lower one on my daughters Xterra that was really obnoxious. I thought it was bushings initially.

cheers.

I can't tell exactly where it is coming from, it just sounds like a bushing squeak. Never heard it before replacing the shocks. I know it's not the new shocks as I drove it for a week with no front shocks and the noise was still there.

My poly bushings used synthetic grease which which was supplied with the kit. I ordered extra and really gooped it on, just for reasons you are describing. No squeeks at all. I'm afraid maybe you need to take the bushing out and regrease it to take care of the noise. I'm guessing uppers like you said, but maybe your strut/tension rods too if they're poly. My lowers were an absolute pain to get out and reinstall, plus you'll have to release your torsion bars to get to them, so I hope it's not them.

Can the poly upper control arm bushings be removed without a press ?

I know from past experience the grease Energy Suspension provides is supposed to be good but from what I recall it really stinks ! LOL

You might be able to, but trust me it will be a whole lot easier to use a press. A press makes that job no big deal.

If you don't have a press already, snag one of the harbor freight ones. They're cheap and you'll find all kinds of uses for it. I use mine for everything from car projects to installing sights on pistols.

poly bushings in the control arms are the worst.

can you tell if they are energy suspension or whatever the other big name in the game is...prothane? I know whiteline tends to use a yellow bushing and they have this nice golfball pattern to hold grease.

an old trick for sway bars is to wrap the bar where it meets the bushing in teflon tape. maybe try some teflon spray and park it sideways on a hill to get it to run into the bushings? last hope is to take out the arms, drill and tap for a zerke fitting and grease em

depending on how stuck they are, you can use a good vice in place of a press. ive done it with marginal success, but when the bushing is vertical you can get a ton of spray lube in there to help.

When I replaced the bushings on the Green truck I found the lower bushings were in excellent shape and the uppers pretty much worn through to the metal. A lot of people opt for the red poly bushings and I think it's because they look cool but the black ES poly bushings are impregnated with graphite while the red ones are not. I have had black ES bushings on Green since 2011 and have had many autoX events on them and no squeaks. Another thing you should check if you haven't already is greasing the spines of the torsion bars, those will squeak. Lastly, only because this happened to me once, is check and make sure your transmission x-member is still attached, if the bolts fall out the x-member will fall and rest on the torsion bars, ask me how I figured this out?!?

I'm pretty sure they are Black Energy Suspension bushings. Thinking of picking up a used set of arms from junkyard and either replacing the bushings with rubber or another set of poly, than just swapping the arms.
