I HAD this problem and went through all the same BS as all of you including the Lexus TSB (which Toyota would not apply). I had multiple visits with the Toyota Technical Field Rep as well.
Toyota's response was always the same, a slight rotation in the rear axle when coming to a firm stop and then a second slight reverse rotation causing the "clunk".
Mine is fixed. For other reasons, I ended up lifting the 4runner a bit via a suspension lift (Donahoe Racing). The new rear springs are a progressive spring with a rate approximately 15-20% greater than stock. The front was lifted to level by a new set of coilovers.
No more clunk whatsoever. My best conclusion was the increase in spring rate in the rear and the leveling of the vehicle (it doesn't slope down so much in front anymore) have eliminated the rotation of the rear axle. The increased spring rate in the front also eliminated a really annoying flutter at certain times on the highway. No new driveshafts, lubing slip yokes, etc.
New rear springs can be fabricated at increased spring rates for less than $100.00 per spring. Front leveling spacer kits can be had from Daystar for a song. Of course there is installation involved. Check with your local 4WD shop.
I can't guarantee this for you, but my clunk is COMPLETELY gone and I have a better handling vehicle.

Sounds like you reduced the angle between the transfer case and rear differential by raising the front. Did you have a problem aligning the front wheels or any other problems with the installation?

No, I had no problems with alignment. I had a 4 wheel drive shop in the Phoenix area do the installation and they use a shop for alignment after installs. Again, I had a NEW and DIFFERENT set of front coilovers installed which were adjustable in height and also increased spring rate. My stock coil/shock combination was very soft so I wanted the increased rate and go one size up on tires.
DAYSTAR makes a couple of different leveling kits for the 4runner. Here is a link to one website that shows the different options for the 4runner. Again, I went with the Donahoe Racing kit but the Daystar leveling kit might work well for a lot less money if you are O.K. with the front spring rate. (The 4runner looks great leveled out).
I don't know for sure if the leveling of the vehicle or the different spring rate in rear, or both, solved the problem, but it is gone which tells me it has nothing to do with the driveshaft, slip yoke, etc.

Do you guys know where I can get a the TSB for this??? I have brought my 4 Runner in 3 times and the mechanics can't seem to find the problem even when I told them that this might be what it is.
Thx for your help.
#2191 of 2607 '04 4 Runner leaking oil in mid-section

I just noticed that my '04 4 Runner is leaking oil or something right under the middle of the car. Help!!

Who's changing the oil? 1) The oil plug has a gasket that should be changed every time the oil pan drain plug is removed. 2) Could the drain plug not be tightened --- I'd check this right away. 3) Do you have the V8, because I have the V6 and can see the oil filter and feel if it's tight, however I don't know where the V8 oil filter is located --- it could be loose, so can someone chime in on V8 oil filters??? Those are my best guesses. Good luck.
Last but not least, since you said oil or something, what color is the something? If it's red then it's tranny fluid.

#2196 of 2607 Battery failure...
Aug 29, 2007 (3:06 pm)
I got a 92 4runner, 4cyl manual. Starts up great, recently parking brake light and battery light on dash stays on, it used to turn off after the truck started moving. And now after driving for about 5 mins, the battery drains, rear abs brake light come on(in dash) and when the truck is turned off, it wont start again cause the battery doesnt have enough juice, but after waiting a while and getting a boost, works fine again, but same thing happens.
Im gessing the alternator is draining the battery cause i cleaned the terminals, checked the wires, all fine... if it is the alternator, are there any tutorials online that i can follow?
