Rear End Whine Solved

I was getting a whine which sounded it was coming from the left rear, the whine only happen between 75 - 80 mph?

Drained the differential oil and all was well, oil flowed out when I removed the fill plug, no burnt smell, no copper residue or metal bearing shreds. Refilled with the correct axle gear oil and tested again but the noise was still there.

My tires were 6.5 years old so I bought new tires, thinking maybe a bad tire was causing the noise. Nope the noise was still there at the same speed range.

So I just figure I would live with it till it got so loud that I couldn't.

This week when I was bleeding the brakes I noticed that the center cap on the left rear was pretty loose so I cleaned up the back side of it and used silicone caulk to secure it.

Yesterday on my first drive after caulking the cap in the whine was gone!

Ohh what a great feeling it was!

The other wheel's center caps can be turned around but not move in and out like the left rear wheel but I'm going to caulk those in too.

Next time, Murray, try a little of your favorite cheese instead of silicone....

I know it's corny, but I couldn't let it go by Murray.

Keep the shiny side up!
