The left upper ball joint in my 89 Civic RT 4WD Wagon seems to have gone south on me, so I need to replace it. I looked on Rock Auto and there are a bunch of parts from different manufacturers, ranging in price from around $12 to $90. I don't know why there is such a big range in prices. I've never worked on these things before and am clueless about which ones are good, etc. Here's the Rock Auto link: http://www.rockauto.com/catalog/raframecatalog.php Can anyone give me some advice on how to proceed? I don't know whether I'm out of my depth here and should just get the car towed to a garage, or give it a shot myself?
