Upper Control Arm

[808rex]

Hi, I was just wondering if there was a difference between the hf and si upper control arms. The reason im asking is because the upper ball joint is totally worn out on my 91 crx si and i have an upper control arm from my friends hf with a good ball joint that i want to replace. Thanks

the hf upper control arms will work on the si, i know the upper control arms for a 90-93 integra will not work.

Ok, because when i installed the hf uca while installing my stock knuckles(previously had gsr's) my car pulls hard to the right and thats the same side the hf uca is at. Or is it because i messed up the suspension geometry when using the gsr setup?? Can i get an alignment and everything will be normal?? Thanks

Are you using HF UCAs on both sides?

And yes, an alignment should fix everything; especially since you've removed the knuckles and installed different ones.
