Hello all
I have just purchased a 105 GX EFI. I have a few niggles to sort out and will get to them slowly but surely.
I have been through this forum and others trying to find some more information on what could be my issue. I have read threads from older Prado's and a very interesting one by @Shayne and his issues with a knock in his drivetrain.
Mine occurs when upshifting and accelerating. it is when the vehicle shifts into the next gear that it does it. on down shifts this knocking sound is not there. Only on upshifts. If you slow the shift down there is no sound and it is smooth. The sound is like a big rubber mallet striking the chassis and you can feel it in the vehicle. Today after reading threads over and over again I though I would lock the center diff and go through the gears. Well, the sound DISAPPEARS completely. Perfectly smooth changes!
Before this discovery today I really thought and was hoping it was something to do with the clutch as it happened only as the gearbox was going into gear on a quicker shift. Now after my tests with the center diff locked, i am back to square one!
Any inputs would be highly appreciated.
