In the front differential of the 2004 Buick Rainer, it is recommended to use SAE 75W-90 gear oil. The differential contains the final set of gears that the power from the engine passes through before reaching the wheels. Differentials require thicker oil than what is typically used in engines or transmissions due to their small size and high operating temperatures. Thicker oil is more resistant to breaking down under the heat generated by the rotating gears. To ensure the protection of your differential from potential damage, it is advised to change the gear oil every 50,000 miles.

Can you explain the process for inspecting the front differential fluid and adding more if necessary? I feel a bit embarrassed asking, as I haven't had much experience with vehicle maintenance. I used to rely on either my father or ex to handle repairs, and now I wish I had learned these skills myself. Recently, I bought a 2004 Buick Rainier, and I've been hearing a noise that resembles a playing card stuck in bicycle spokes when I accelerate forward.
