Hey guys I need some input and information for my next repair on my GS. I have a vibration in the front end and steeting wheel so I started looking around and found that my left front upper ball joint has a lot of play so its time to replace it. I am looking on Rockauto.com and there are several options available including Dorman, Moog, Mevotech and Beck/Arnley. I don't have much experience with any of the manufacturers except Beck/Arnley which I used for lower ball joints and a trans mount which seem to be holding up pretty well. Just wondering what you guys are using and how well or poorly its working out for you. Thanks for any info in advance!!
