My brother helped me replace the lower control arm on my 92 toyota celica. Now when I drive it though, you can hear the roter's grinding and the brakes work like total shit. Infact, after the initial test drive, it seems the brakes are locked up. Someone told me that the bolt for the control arm is too tight and causing this issue. they say it needs to be finger loose, with the cotter pin in place holding it. Instead, right now, it's bolted really tight, with the cotter pin in. He says for reasons I can't recall that this causes the issue I'm having. It ever so slightly makes sense since the issue didn't start until we replaced the control arm. So. Anybody have suggestions?
