Hey I had a machine shop put in my new bushings and I am putting the upper ball joints in now. If I clamp the shaft in a vice and turn the arms they squeak. I looked at the bushings and I can see the grease has been applied (I asked them to do it they say they did). Are they just squeaking because they don't have any load on them? Or should I take this as a problem and not reinstall them? Thanks for all the help on the previous posts.

Yeah, mine squeek right now too... The car is up on jacks with the nutz for the control arms just hand tightened. Waiting on my D**N springs. I lubed the cross shaft with some lithium grease, hoping that will make things quiet once everything get tightened down... I'll be one ANGRY person if they still make noise once it's all assembled.. Remember to get the weight of the vehicle on the suspension before tightening down the control arm bolts. I'm going to use my Rhino ramps for this.

BTW Did you ever get the LOWER balljoints in?

Not yet, the alternative shop does not work on weekends. I may go see them on Monday, or I might take them to the race shop (from the Late Model I used to work on) next weekend and do it there.

You are likely aware the bushings are not bonded.
That is to say you can take them apart.
If you push like hell the inner sleeve will come out. (Might have to use a big and little socket with a vice)
Next you can push out the bushing itself.

Although the things come with "magic" lube I have had good success slathering them with silicon brake lube. There are many brands but I use
Kleen-flo "EZE-SLIDE" #331.
Just lube them to death and put them back together.
If you are really worried you can drill and tap the housing for a grease fitting, grind a groove in the outer bushing and drill a few holes to the center.
On my rear bushings I went the other way.
I drilled the bolts and sleeves. I now have grease fittings on the end of the bolts but honestly have not lubed the bushings in over a year.
Hope this helps somewhat.

Gerry, now isn't the reason for the Poly Graphite bushings so that they don't squeek? The graphite is supposed to be a lubricant, correct?

Tom, I think supposed to is the operative phrase.
My Cutlass has them in the back as well and it was quite noisy until I slimed them.

I was thinking about the PST's until I read this. Everyone says the ES Hyperflex bushings squeek, and you can get those with zerk fittings installed... I'm thinking why pay extra for the graphite impregnated stuff if you still have to grease 'em? I'll pass.

Still... I need to decide soon between the ES Hyperflex bushings or the significantly more expensive Del-a-lum bushings.

It's in the PST instructions that you still have to grease them before install. But after that, they are *supposedly* good to go. I guess I'll find out this spring.

Guys,

They only have to be greased ONCE - before install. Check out this thread for info on doing it. The bushings will never squeak if properly greased before install. Also, as far as I am aware, the only bushings available from Energy with zerks are the front sway bar bushings. Hope this helps.
