Poly bushings squeak non stop!

[CircuitMonster]

So I had a good shop install my rear subframe, control arm, and differential bushings about a month ago and now there squeaking non stop. Even with just casual driving. Is there anything I can do now to help stop/limit it? If so what would you recommend. Please help.

Thanks.

my cab poly used to squeak crazy,what I did is remove poly bushing then lube it up with green grease and reinstall poly bushing back in.

vato zone carry green grease.

Your shop should have greased those rtabs with ATE Plastilube or its equivalent.

Yeah I can't do the work myself since I don't have all the tools and stuff to drop the subframe.

I had castros down in la do the work. Which is a good shop but is about 2 hours out from my location

Poly bushings will need to lubricated every few months. Synthetic brake grease is easy to find and works well.

My big question is will I have to remove everything to lube them or is there a spray or something that can work since like I said I don't have a way to drop the subframe.

The bushings have to come out to get lube on the parts that squeak.

If this is a daily driver, consider switching back to OE bushings for the trailing arms and sway bars.

for moveable bushings I'd recommend a silicone-based Dielectric grease. It's intended use is for electrical connections, but has the ideal properties for lubing urethane bushings. Smear the stuff on ALL mating rubber surfaces.

Ideal properties...
-Sticky (non-curing), it's not going anywhere, in other words, very long squeak-free driving experience.
-Waterproof, since you don't want water getting into an electrical connection, it'd make sense for an urethane bushing to keep rain/grit from penetrating the bushing.
-Available, cheaply, from just about any decent hardware/electric store ( http://www.solar-electric.com/disigr.html ).

We (and just about every other bushing maker) do include small tubes of the stuff with every bushing set that goes out, but it's certainly nice to have some around the garage.

Hope that helps.

why not use green grease instead of Dielectric grease?

[jlevie]

In my experience it doesn't matter that much what kind of grease you use as long as it is synthetic. All grease is more or less waterproof. But over time it will get squeezed out and washed away.

Certainly more than one way to skin a cat, I just prefer what I know to work well.

Here's a summarized MSDS of the GG.

I had these in another car, they will squeak no matter what you do. Unless you take them out and re-grease them. I went OE this time around.

I have always use copper or aluminum anti seize on all my urathane bushing with good luck.

The squeek is caused by urathane rubbing against steel. When the powdered copper or aluminum imbeds itself into the urathane it prevents squeeking along with the libe in the anti seize. It seems to out last grease too.
