I have read a couple of threads on here where guys are complaining about a clunk or poping sound coming from the front end when hitting small bumps on the road. I would say that I have the exact same problem with my 2005 Titan King cab 4wd. My truck has the front end leveled with the custom Bilstein 5100/Eibach spring combo that PRG sells w/TC upper control arms. I have only owned the truck for 2 months or so. I love it, except for this problem.
Similar to other descriptions of the sound that I am hearing, the clunk sound occurs in situations where the wheels are dropping over things like say on the backside of a speedbump, or dropping off a curb, or a small rock drop when wheeling, or a depression in the pavement. Also similar to other reports, I can feel the clunk in the floor. Between the sound and the sensation, it feels very sloppy in the front end - vertically - like something in the suspension is dropping vertically due to something worn out. As far as I can tell, it is happening on both sides.
There is a very long thread (2012) mostly about lower control arm bushings possibly being the culprit. I read through all 9 pages and I'm not sure if consensus was met among all the members trying to figure the problem out. The thread is here:

I am posting this to see if this issue has been figured out since then. It's really driving me nuts, because it feels like the front end is falling apart.
One reason I suspect that it could be worn out lower control arm bushings, or the arms' pivots themselves, is because I had basically the same sound and sensation with my 2000 Tundra. A 4x4 shop replaced the LCA bushings, which meant replacing the arms themselves, and ($1600 later) the problem was solved. I guess I am hoping that I don't have to spend that money on this truck as well!
Can anyone please comment on this issue and what the problem/fix is?
Thanks for the help.
