UMT Posted September 28, 2012 Share Posted September 28, 2012 99 Impreza Outback Sport. Ok, guys.. Been meaning to replace the struts on this car anyway but have developed at 'knock' noise at times when hitting a bump on rough roads. I thought it was maybe due for ball joints also but jacked up front end and put a small pry bar on the ball joints to check for looseness but they seem tight. Checked everything I could under the car, and can't find anything loose anywhere. Any ideas what else I could check for? 206k miles on the car. Thanks, UMT Quote Link to comment Share on other sites More sharing options...
avk Posted September 28, 2012 Share Posted September 28, 2012 Sway bar links and/or bushings would be my guess, but I only had that happen on my minivan, which is well known for this type of problem. Quote Link to comment Share on other sites More sharing options...
UMT Posted September 29, 2012 Author Share Posted September 29, 2012 Looked at those and looks like they (like everything else under there) maybe need replacing but don't think that's the problem. Any other ideas? Right now, I think I'm going to start with the struts and take it from there. Thanks, UMT Quote Link to comment Share on other sites More sharing options...
99ImprezaOSport Posted September 29, 2012 Share Posted September 29, 2012 Years ago, my Volkswagen front struts would actual become loose at the top mount and knock, especially on rough roads. With so many components moving in the suspension there can be one or numerous things creating the knocking noise. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted September 29, 2012 Share Posted September 29, 2012 Check the inner tie rod ends. For some reason they like to wear out on these cars and can be hard to identify. If the steering rack boots have ever been split and replaced there's a good chance the inner rod joint got dirt/sand in it and is now worn just enough to clunk every now and then. Strut mounts on these seem to go bad as well, but it's worth checking the inner rod ends. Quote Link to comment Share on other sites More sharing options...
ocei77 Posted September 29, 2012 Share Posted September 29, 2012 Probably struts. I have the exact same vehicle. Had same issues, but I knew the struts had to be replaced. When removed, the strut came down by its own weight! Do search on replacing, for you don't have to separate the brake lines to remove or replace. O.
