I recently had my front and rear sway bars replaced with the Whiteline adjustable set. I opted for the stiffer setting. Now I am hearing a definate thump from the rear end on hard corners at any speed. If there was an issue with the bars
what should I be looking for under the car? Any ideas appreciated, thanks in advance!

Make sure you didn't install the rear one upside down or anything. If you did, you'll see the apex in the middle of the bar touching (or almost touching) the exhaust. It makes for a noisy and stiff ride.

 

Make sure you've mounted the lateral movement stops & the bar is positioned laterally as the original was. Note that if the bar is positioned incorrectly, the bar can meet the little articulated level sensor arm on the left side and make noise or damage it.
