Thud / Knock !! Driveshaft? Axel?

[frohbego]

Please also see my original post. Looking for help on this.

-------------

Still getting a Thud / Knock !!
Ok so heres what i have done so far.

Oil Change
Front rear & diff change
Trasfer case change
Transmission change

Yesterday i Lubed all the zerks on the drive shaft and u-joints.

Today still getting the same thud / knock noise. I do not think its the transmission at all.. Shifts very smooth. But it sounds and feels like its from the driveshaft of the axle.

Also i got about 25 miles from home with out it doing it. Once i got off the highway on back roads it started up again. I noticed it when i slowed down and when the car downshifted. But it also does the thud/knock when i accelerate usally right after the car downshifts.

What should i do now?

Thanks for everyone help!

Happens to us all, very common. A little search and you'll see. There's a TSB for the Lexus, but not the 4R. Best you can do is lube the driveshafts every oil change or two...

Thanks for the responce... I was only able to find 2 zerks in the front of the rear drive shaft. I have an 02 sr5 runner.

Hopefully i'm decribing this correctly

There should be 8 of them

There is write-up on it on yotatech.com.

Follow up....

just had ny local shop guy take a look at it. The only thing he thinks might be wronge is that there may be too much play in the front drive/trans axle. He said jeeps have no play and wasent sure if the 4runners should?

Anyone know anything about this?

Thanks!!

Even worse..

I also just noticed that the knock/thud happens more oftan and louder with the Air Conditioning on.
