Squeekie Urethane Bushings

Does anyone have a solution to quieting up urethane bushings. I have a TCI IFS and my lower a-arm bushings creek. Drives me batty. I have used everything from water to Tri-Flow (teflon spray) and sometimes it shuts them up for a few weeks and then returns. I know turn the stereo up and insert ear plugs.

Can you switch them out with polygraphite bushings from TCI or somebody else, they won`t squeak! Try here http://www.p-s-t.com/polybu2.html

Rick5150 thank you for that information. The entire front end is TCI so I'll check on that.

The graphite impregnated polyurethane bushings still bind and squeak.

There are 2 ways to keep them from squeaking (binding is another story).
-Ditch them for high durometer rubber bushings (which aren't available for most applications).
-Get bushings with the grooves in the ID so there is some place for grease to flow. Then tap the outer sleeve for a grease zerk, drill the bushing under the zerk so grease can get in, and grease them at every oil change. You can also drill holes through the bolts and inner sleeves but I don't like that idea so much.

Thanks Triaged. First I've sent off an e-mail to a local TCI dealer to find out if there is an aftermaket bushing to fit my TCI suspension then I will go from there.

I have polygraphite that squeaks. The problem is the polyurethane's properties. They just squeak. They will always squeak. Even the ones with grease fittings squeak.

I'm taking mine out and using delrin/aluminum instead.

The ones that I have with grooves in them don't squeak when greased. The ones that don't have the grooves are VERY hard to grease - so hard that it locks the gun onto the zerk and I almost can't get it off.

As for Acetal (Delrin is a trade name for acetal) I'm not sure I want to go that far. I have been thinking of going back to rubber. The PTFE (Teflon) impregnated Acetal is nice stuff. I find it interesting that it actually has a static coefficient of friction that is lower than the dynamic (not that anyone cares...)

I've been contemplating the same EXACT problem. The urethane doesn't easily flex torsionally and adds way too much resistance to the suspension. The rubber is allowed to torsionally flex more, but deflects easily. The Acetal has lower friction than both urethane and rubber, but transmits a little more NVH into the cabin. Its a conundrum to say the least. I didn't like the rubber, I hate the poly-graphite, but will I like the Delrin?

But as far as handling is concerned, getting that friction OUT of the bushings is one of the keys to being able to tune it right.

Part of the problem with Acetal is that it doesn't deflect. When the axis of the 2 bushing bores are not exactly in line it will cause binding. This is why some people just step right up to using PTFE lined spherical bearings (aka monoballs or uniballs). It takes some work on a lathe and some welding...but will get rid of all the binding in the suspension.

So I finally got a response back from TCI and they say use white lithium grease which means taking the upper and lower a-arms off and removing the bushings and reinstalling them. Oh what fun. I can also at that stage see how far I can throw them into the back 40.

lol!! If you do have to pull them out it would be a good time to drill and tap them for zerks

PB Penetrating catalyst followed by Marvel mystery oil has ridden bushing squeaks for me. Probably not the technical/professional solution but it works....

Try a little NeverSeeze on the bushings when installing in their receiver and the bolt holes. This will keep them quiet for a long time.
