When my FSD failed it knocked.
The most common cause of knock in the rear section is exhaust mount related. While on your back grasp the exhaust and swing left & right, watch & listen.
A loose drop link will knock.
A loose strut will knock.
If it is an early 2003 model, the trailing arm bushings could be torn. With a mirror and flashlight the bushing/mount can be inspected, also look upward at the bracket for signs it may be shifting.
Look for a crack in the lower control arm.
Grab, wiggle, and observe everything.
If all is OK down below, look at the boot hatch latch etc.

Def check to make sure the nuts on the rear struts are tight, I've seen them come loose.

also make sure the bushings for the swaybar are not too lose. if they got too warn before you lubed it, it could be moving. i have seen this before.

1.How old/many miles when it failed?
2.Did you like the Koni FSDs(ride, damping,rebound)?
3.How did they compare with other shocks that you've used?
4.Application/scenario that I'm talking about is SPIRITED street.
Thank you all and now back to your regularly scheduled thread.
