Exclamation Found the vibration problem - damn guibo's

Suffered severe vibration under heavy acceleration a few weeks ago and decided to poke around and see what i could find...whoa!!! a slightly farked now the repairs begin.

Firstly jack up the car, secure the vehicle using proper stands and ramps and DO NOT get under the car unless you're confident its totally secure!.

I will point out that most people FAILED to explain in this and other forums when changing a guibo, is that when removing all bolts and brackets, EVERYONE who wrote about their repairs in the forums failed to let us know that the gearbox is tail end heavy and will drop at least a good 5 - 10" SUDDENLY when the last bolt has been removed, ask me how i know, the back end of the gearbox suddenly gave way and just missed my head anyways i quickly borrowed the scissor lift jack out of the other vehicle and using a few blocks of wood helped secure the gearbox back into place...a crude but an effective manner

Finally removing the tail shaft revealed the culprit...stealers are currently on their annual holiday break but will open again later this week where a guibo has been sourced.

I'll take a few more photo's and will explain in a step by step method how this can be done by you too if required, saving you quite a bit of money at the same time.

Anyways...Happy New Year and best wishes to all for 2011
