Antisway bar for front is a PITA...you have to drop the subframe...Unless you really want to do it, I'd just change out the endlinks. IPD sells a heavy duty one that's only a couple of bucks more than the regular ones...you'll have to call them as they aren't listed on their site. Also a guy called "Slater" on VolvoSpeed.com sells some beefed up ones that have an even better reputation. You'll probably have to IM him to get a price...I have no idea. Swaybar bushings are usually pretty strong and don't go bad unless you have really high miles and the bad endlinks have been yanking the rollbar around for awhile. Good luck, and I'm glad you found the cause of the "clunk."
