Author Topic:   which a arm bushings to use??

Whats everyones opinion on upper and lower a arm bushings. stock a arms.

I have ran energy suspension from summit for 55.00 complete set.

And also ran some nylon ones with a steel bushing for the bolt to go thru on the lowers.

I have never ran straight steel thinking some give would be good for rubbing but they are available for uppers and lowers.

What do you guys think?

eurethane are 55.00

steel or nylon are 100.00 so cost isnt the issue.

thanks for you opinions in advance.

i think steel is the way to go. easy to swap if you bend an a-arm. but that would never happen anyway now....would it??

from what i have read on here the steal are a pain to maintain and seize up every now and then personally i'd go with the euro

I vote for urethane. On dirt I'd think steel would require too much maintenance for me. Plus with urethane you can have a little mis-alignment (after wheel to wheel contact), where steel wouldn;t allow that.

the trick is to not have any binds in the lowers. with the arm off on a bench. take a piece of 1/2 rod, or even threaded rod. stick it through both bushings, and tack weld them in. they dont need to be completely welded all around. dont forget to leave the grease fitting on the side facing down so yo ucan grease it. done that before. you forget all about it until you go to grease it and it aint there!!
The light weight Afcos are nice.

When it comes to bushings some people think that I have bad reasoning behind this. I always ran steel EXCEPT in the left upper. Seems like when someone decides to bounce off me, its always there. And that side takes less pressure in the turns than the right. Just an idea.

that is a decent Idea, though I plan to be going on the inside of more people than are going inside me, so maybe Im a eurethane guy??

I am still kinda leaning towards the eurethane so I dont have to grease them etc.

the STEEL uper bushings "AFCO" (in stock upper arm) have a fairly sloppy fit with the crosshaft. i have even used new shafts from "MOOG" and still had this problem. the grease helps, but there loose in about a lap anyway. anyone else? ideas? if there is .020" play at the bushing, imagine whats going on at the wheel/tire.but i still beleive you need to get all the bind out of the front end you can, it really helps.

Food for thought:

If the control arm moves in the same Axis with both stock rubber(new, of course) and steel, which is better?

What is the cost difference between the Moog of the shelf and solid steel? Could that money be spent on other areas of the car?

not trying to soil anyones wheaties here, but sometimes we over engineer oueselves. Not to say that the steel would not be the ultimate, but is it really needed or is it another way to make a $15,000 street stock?

i dont think the deflection (in the rubber bushings) is as big an issue as bind. it affects the way the car handles, setups on the scales are more consistant when there is no bind. i disconect the shocks before scaling the car for this same reason. as far as the rubber bushings are concerned, you may never know the diffirence when your driving the car, but its just one more variable to chase. 2cents worth.
