Differential Assembly for Suzuki Vehicles

Suzuki fields three quite different automatics locally — a conventional torque-converter automatic, a CVT, and the AMT automated manual used on the budget cars. The AMT is a manual gearbox with an actuator bolted to it, so its parts have nothing in common with either of the others despite all three being sold as "auto". Getting that wrong is the most expensive mistake on this page. In practice the decision in front of you is whether a repair, a reconditioned unit or a good used gearbox represents the best value on a car of this age.

Whether the car is manual, AMT, CVT or a conventional automatic, plus which engine sits in front of it. With that we can usually confirm the right part quickly, and we'll tell you whether we're quoting new, aftermarket or good used rather than leaving you to guess.

Load it and listen. A wheel bearing changes note when you sweep the car left and right at a steady speed, because you are shifting weight on and off it. A differential changes note when you swap between pulling and coasting at the same road speed. If the noise ignores your steering but reacts to the throttle, look at the diff.

They can, but the setup is skilled work. Pinion depth, backlash and bearing preload all have to be measured and shimmed correctly, and a set that is out by a fraction will howl within a few thousand kilometres. Many owners find a good complete second-hand assembly is faster and more predictable. List your model year and gearbox type in the quote form and we will cost both options.

Quite possibly. On the front-wheel-drive models the differential and final drive live inside the gearbox, so a worn diff bearing means opening the box. Once you count the strip, parts and rebuild time, a known-good used gearbox is often the practical answer.

It matters completely. Front and rear differentials must run the same ratio or the transfer case and driveline will fight each other every time four-wheel drive is engaged. Never mix an axle from a different derivative on ratio alone. Give us the VIN and we will match the exact part.

Follow the interval in your service book rather than a number off the internet, and shorten it if the car works hard. Deep water crossings can push water past a breather or seal, and heavy dust finds its way in through a tired pinion seal, so an axle that lives on gravel deserves an oil check more often than the book assumes.
