My car is going to be on jackstands for a while so Ive been looking at differnt upgrades. Im thiniking about making my own spherical bearing setup, but I'm not sure what is a good grade of bearing for our application? Where do you guys get your bearings from? I found these websites
http://www.aurorabearing.com/

I dont have a problem measuring and pressing out bearings, but Im not sure which grade bearing is good for oour cars? Nylone race, steel, alloy, aerospace? What is good enough quality for our cars without breaking my bank?

 

spherical bearings for what parts?
what car?
why do you think spherical bearings are an upgrade? they wear out faster which isn't always a good idea on a street car unless you like servicing/replacing them often.

not criticizing, just curious...

 

for the trailing arms on a 2nd gen. I just hear all these things about binding issues, so polyurethane doesnt sound like such a good upgrade, and even worse, delrin

 

Aurora is commonly used on race cars. Look at the load bearing numbers, and try to get this as high as possible. Look for lined races, they'll usually keep the slop down better over time compared to metal on metal. Consider some sort of system to keep dust and dirt out of them, some places sell cupped boots that can be installed like washers to help with this. If there's choices of widths, go wide, you won't need much angle on them. Get as big a bearing as you can fit in there. Don't limit yourself to metric bearings, an imperial with a sleeved down center will work too.

 

You do know what your getting into? I would not recommend a lot of these bearings and rod-ends for a street car. They tend to get so noisy and make everything so harsh. My bro had some after-market control arms on his firebird with rod ends. They wore out so fast... then, he had another pair which i think were ptfe lined, those wore out too! I'm sure the biggest problem is the location, they were located in a spot thats exposed to a lot of grime and dirt, that just eats them away. We use spherical bearings on my schools formula car all the time, but that never sees the miles and grime that a street car sees.

I know they make sealed rod ends, those should last a bit longer. I would definitely check those out.

 

Thanks, I will not be drinving this car often, but I will try to check out sealed bearings. Are you talking about regular ball joints with boots? I would go stiffer in the rear, but it jsut seems like a binding situation. I used to own an older car with a similar setup and binding is definatley an issue, es[ecially for people that really want to take aggresive turns. I would hate to be in the middle of a turn and have your suspension fail, only to cause you flying into the sdie, where more bad stuff happens. This car will not be dailey driven, at the most, weekend car/track days

 

no, im talking about rod ends that have rubber seals on them. Just look at the aurora catalog, im sure they have some in their.
