rear end noise

so my rear has been making alot of noise lately, usually when i hit a bump or dip. i had the MLLs on the rear so i threw a set of OEM XK shocks in the rear to inspect the shocks and see if one of the rubber sleeves has moved, causing some contact. the passenger side sleeve had moved but, after swapping shocks its still making noise. i know my bwoody links have been prone to being noisy from time to time, so i hit the top of the link with some white lithium grease, didnt hit the bottom. ill be hitting the bottom after work, but what else could it be? i have the greaseable energy bushings on my rear addco, so im kind of ruling that out. thoughts?

So has mine and I attributed it to the MLLs be default...... perhaps I'll have to rethink that.
