On most rear-wheel drive vehicles, a flex disc, sometimes called a giubo (which, you may be interested to know, is properly pronounced JOO-boh), is fitted where the gearbox and propshaft flanges meet. Flex discs are designed to help smooth out the transfer of torque between the gearbox and the rear wheels. You can see it in place on my E39 below, with the gearbox crossmember removed, which you need out of the way in order to access the flex disc.
The photo below shows the old flex disc from my car on the left, and the new one on the right. Now, if you’ve been following this blog for any length of time, you will know that I replaced this last March.

Next to your engine and gearbox, maintaining your suspension is one of the best things you can do for your car. The suspension is both what keeps you connected to the road, and what absorbs all the road’s imperfections, and in a bad state of repair, it will hurt your fuel economy, decrease the lifespan of your tyres, and adversely affect your car’s ride and handling, not to mention make your car less safe to operate.
Thankfully, rebuilding a suspension on many cars is not a terribly expensive or exceedingly difficult undertaking, and doing so can make a tired old car feel much newer again. It is also a job that can quite often be done an average DIY-er.
