I used my rubber mallet, and found that my newly installed rear stabilizer bushing had squeezed out of the "C" clamp. I had used my stock ones, as I liked how they were curved in the bottom to kinda clamp the mounting surface. After finding that, I decided to dig out the new clamps I got with the Poly bushings, and put those on.
I second the control arms. There were 2 different styles of bushings used by Toyota. The worst for strength was designed for a lot more flex then the first half of the 3rd gen If a little play happens in one of the bushings then the other bushings now take more force. Its not noticeable at first but its something to check.
The bushings can be replace with a simple leaf spring type bushing but its something that will all have to be done custom there is no kit for it and to get the old one out fire is needed.
Another thing is of one of the bolts is slightly loose and your axle experiences a lot of use it is possible to have one of the bolt holes on the axle or the frame become oblong and create a clunking. If thats the case then the hole has to be welded and drilled back to spec or drill it out and upgrade to large hyme joints
The best way to check is jack the truck up with the axle hanging there nothing under it to support it. Grab a end and man handle it and look for any movement. It can be small like less then 1/16 but when your talking about 2 tuns and a bump every little bit makes a difference.
been there done that good luck

OK I said this on page one.
I had this same problem, I replace the shocks, panhard bar, rear breaks adjusted ( helped out the stoping issue), and do course the drive line. If you would push back and forth on the rear wheel in towards the car, you have to get it to sway back and forth it will most likely start to clunk... Wheel bearing. I had never had a wheel bearing make a sound like this and it took some time figuring it out.

I could physically see the grease running out of the bearing; I knew it was only time.
Before I had it changed out, at work, there are three speed bumps and every time i would hear "clunk clunk" as I passed over them. I had changed out both CVs, LBJs, and OTRs to no avail. The ITRs looked fine at the time and the CA bushings had only 100,000 miles on them.

There are no 4WD shops that are open on the weekend so I made an appointment at the local Toyota dealership to let them try and figure it out. I will ask them to check everything mentioned above but at this point I am just too tired to mess with it anymore. This evening I am going to switch gears since it is cool again and work on my 1972 240Z. I will post up my results from the Toyota dealership later this weekend.
Small Update: Round Rock Toyota worked on my T4R off and on all day Saturday. They fully agree there is something wrong on the passenger rear side of the vehicle. However as of late Saturday evening they have not been able to determine to the cause. Two master mechanics were left scratching their heads so today they are going to drive it with a Chassis Ears system attached to see if they can pin point it. Hopefully I will know more later today.
Problem Solved! The guys at Round Rock Toyota got it figured out. According to the service guy, when the hitch was installed whoever installed it knocked one of the bumper alignment brackets out of orientation. It also messed up a thick piece of felt like material that sits between the bracket and frame. They took everything apart, replaced the felt material, and put everything back together properly. Needless to say the drive to work was very quiet and much more enjoyable. I have to hand it to the guys at Toyota, not only did they fix the true problem but they charged me what I thought was a more than fair price for it all, $112.00 out the door.

Thanks for posting the solution. I didn't know about the felt isolator.
would you happen to have any photos of this felt material?
Cheap easy fix for clunk in rear of 4runner
I had a loud clunk coming from the driver side rear of my 2000 4runner when going over bumps. I looked every where underneath the rear, jumped up and down on bumper, removed the spare and tried the above ...n/g could not find it. In one thread I read about a body/frame bushing being worn out. I found it and although it look ok turns out it was broken above where I couldn't see..
When looking from underneath. There is a 3" circle in the body with a threaded rod and nut in the center. Mine had the bushing but the threads and nut were corroded. I went to H/D and bought Great Stuff foam insulation in a can and used it to fill in above the bushing where I could not see. I also filled in the frame where a rusted single leaf spring was to stabilize that also. I let the truck sit for a day and it worked. About a month later it started coming back so I figured it compressed. I then picked up a tube of gasket in a can which is more dense, squirted it in the same area and that has done it....it's been two years without a clunk. Hope this helps...saved a lot of work, it's easy and cheap!
