Another "clunk" thread - ignore the noise? (2004 WJ)

So with my 2" BB installed, I found a "clunk" sometimes occurs from what appears to be the right-rear wheel area. Now, before you go talking about torquing bolts, etc., be aware that this clunk existed BEFORE I installed the lift. At first I thought it was just the stock shocks blown out - but since it persists, I am very confused.

I can confirm that the rear shock mount and linkage bolts are torqued perfectly to spec. The coil was seated properly, and everything with the lift was in order. As for the sound, it will not occur with any normal bump, deep pothole, etc. It almost requires 2-to-3 consecutive bumps in the road to get the rear rocking. Even then, it's not a loud CLUNK, it's almost a subtle "thud"... and when I go over multiple bumps it sounds like a "wobble". I'm sure this isn't making any sense, but I'm wondering if some one could suggest where I should begin...

Or should I just ignore the sound??

When does this "clunk" occur? I had a similar "thud" noise with my ZJ (completely stock) and the U-joints were shot.

It's *usually* when hitting a few moderately sized bumps right in a row, and the back gets a little rocked around. If I do single bumps - like run over a curb or something - it doesn't happen. I have to down an alley with a schitt ton of potholes, or something, at a good speed to get it to occur. But it's definitely coming from the rear, and sounds like rear-right.

check out your control arm bushings on the side the sound is coming from, and I know the balljoint in the upper rear a-arm starts clunking annoyingly when it gets worn out.

I was just about to say... this is the EXACT same sound I had on my Explorer when the balljoints were shot. Cripes... another drop in the bucket!!!!
