Your GMC axle assembly is an essential part in the transfer of power from the engine, where it is created, through the drive train parts, and to the wheels, where that power is translated into motion. There are a variety of symptoms that can indicate that you may be well on your way to needing a new GMC axle assembly. However, you'll need to conduct a bit of careful investigation to be sure, as the symptoms of a failing GMC axle assembly are similar and even the same as those of a variety of other mechanical problems. These symptoms include clicking noises when you turn the steering wheel fully in one direction or the other and when you are driving in the lower speed ranges, and a serious vibration when pressing down on the fuel pedal or while applying the brakes. If your tracking of symptoms eliminates other possibilities and it looks like your GMC axle assembly is the only remaining viable source for your symptoms, then your best bet is to start planning your GMC axle assembly replacement project. If you're going to replace your GMC axle assembly yourself, you'd better plan on a full afternoon of labor, as you know how it is once you get started -- there's usually one or more of the classic time eaters to contend with, such as the rusted in place bolts and other automotive repair joys.
