Towards the end of 2001, I had a set of rear sway bar billet brackets with teflon impregnated nylon made to replace the entire stock brackets.

To this day I have been very happy with the results. Although it does transmit a little more suspension noise than rubber (as Jim mentioned) I don't have any problems with squeaking.

They're just about wore out and my next set of nylon material will be Delrin.

 

Yes.

Low mileage 10,000 Konis yellow, 2 years old. Lifted the car with front end up high. Used a jack to slowly lift one wheel, no slop on the shock rubber eye bushing at the base.


And why would the slop appear after the car has been driven 15-20 miles??? Once rubber is compressed, its hysterisis isn't so good anymore regardless of hot or cold.

 

Perhaps it's ur deliverence.

U certainly didn't come on very smooth on a forum that has alot of ********* hanging in the breeze.

I'm not the only one that thinks ur trying to dismiss Jimlab's bushings as POS door stops.

At least he was pro-active in making something that would help our cars.

Jim has been one of the best technical contributor ( even though he can blow up taller than Mt. St. Helens at times ) on the forum and most other automotive forums.

Your contributions pale in comparison to his.

 

I don't disagree with you. Please keep all your comments pertinent to your problem though rather than bashing on projects you don't like. You don't come off as credible by making this a personal argument.

 

BTW, I use Redline grease for the front polyurethane bushings that came with the Addco kit.

No noise, even after 4 years of installation.

 

Making childish and irrelevant references to the current state of my car was what prompted my comment about your behavior. Direct cause and effect.

If I already had the molds to make bushings, why would I have the rest machined? All of the bushings have been machined. Maybe you should quit making assumptions and fabricating facts to try to support your position.

 

he appears to be under the impression that nylon is self lubricating in his previous posts

How can an attorney miss those details?

Scary isn't it?

 

Nylon is well-known to be a self-lubricating polymer, hence it's wide use in applications like gears. Obviously, though, it's self-lubricating properties aren't sufficient for suspension bushings.

Poman: You are being an ***.

Jim is also generally an ***, but his posts are very entertaining and the technical content is usually pretty good too

 

I'm just chiming in to say that I have had my bushings in for about 3k miles with no ill effects what so ever. I used Marine lithium lube and installed zerks, but have not greased them since install. I lubed up the pins real well, installed, and then hit them with the grease gun before putting it on the ground again. Yea, its messy because grease comes out all around the pin, but thats ok, I know the job is done.

I will likely re-grease at next oil change now...even though my original plan was to re-lube every other oil change.

 

Well we need more data points on this.

I'm going to try Marine grease next.

Do you have the brand name?

 

poman there are some on the mcmasters site just do a search for marine grease. On the site it mentions that polyurea seems to have some better qualities. It's on mcmaster page 1988 info on the grease types is on page 1986.

Like you mine squeek like a **** but my mechanic did the install so I am not sure about how well they lubed the pins...also the car sat at the body shop for a month before moving...that could have effected things. I'll do a update after my car gets back from the bodyshop again.

 

I have to say, today was the most entertaining in a long time.

I have basically written off these bushings: the hardest part is trying to find the mental energy and time to remove and install the OEM bushings.

As to Jim defense of his bushings: that's his position: they're the product of his energy. But to automatically start blaming people doesn't stand him in good stead. THis brings back to mind of the old Constellation airplanes. They started falling out of the sky and guess what? it's the pilot, the mechanics, the airlines fault. Turned out it was fatigue on the airframe.

My position is to report my experience notwithstanding the fact that I violated my cardinal rule of never buying insufficiently developed parts from a guy in his garage.

 

Dude, mine doesn't squeak. I know what squeaking is like b/c I have the ST sway bar and polyurethane red bushings. They squeak like little rats.

My car DOES NOT SQUEAK. IT CLUNKS like when you reverse and hit the brakes on the OEM bushings. AND IT CLUNKS if the road is not perfectly glass smooth.

 

sorry I should, clarify. I get BOTH squeeks and clunks...

 

Thread edited. Thread stays on topic or it gets locked and warnings issued to anyone involved.

 

Got it from mcmaster's. I'll have to take a look at the tube later.

 

This is one fast glowing thread
From page 3-7 in no time

Keep it clean guys.

 

Jim quick question about your diff mounts. Since the diff isn't designed to move as much as the suspension arms, would these diff bushings need to be lubed as frequently as the other bushings?

 

I have to admit I was all ready to buy a press and get to work on these things but after reading this thread I'm having second thoughts....for a track car no doubt they are worth the extra hassle, for a street car I tend to agree with damonb, I don't want to have to jack up the car and crawl around lubing bushings with every oil change

 

Now that no one is calling me name I feel like I'm able to carry on a discourse in a civilized manner.


If it's just an increase in the overall level of noise such as when I start my drive to work (i.e., a cold start) I wouldn't mind. That is to be expected with stiff couplings like a Heim joint.

The problem is that after 15-20 miles, the clunking is very pronounced to the point that I'm afraid to throw the car into a tight turn as the front bushings make a huge rackets like an old wooden battleship tacking into the wind, groaning and clunking as I go through the turn.

You can actually feel the sharp impact of the clunks through the steering wheel too.

On the drive home today when the weather was about 70F, the clunking seems less. Why is this dependent on ambient temperature is what is confounding me.

If you're local to D.C., I'm inclined to give you a spin to illustrate what I'm talking about.

 

They don't need to be lubed at all, really. The differential doesn't move significantly once they're installed.

LOL

poman, I will say you are quite accomplished at the colorful analogies

 

Yes, he certainly has a flair for the dramatic, doesn't he?

 

He is a lawyer and is trained in the arts of words.
