Question

A drive axle lubricant is a milky color. The most likely cause is:

(A) metal contamination.
(B) mixing lubricant types.
(C) gasket sealer contamination. (D) water contamination.

Answer 1

The most likely cause for milky drive axle lubricant is water contamination.

Step-by-step explanation:

The most likely cause for a drive axle lubricant to have a milky color is water contamination.

Water can enter the lubricant through various ways, such as a damaged axle seal or condensation buildup. When water mixes with the lubricant, it can cause the fluid to appear milky.

To address this issue, it is important to inspect the axle seal for any damage and replace it if necessary. Additionally, if the vehicle is exposed to water during off-roading or frequent submersion, it may be beneficial to use a differential breather kit or other protective measures.
