I looked at my rear diff. housing yesterday and noticed that some of it appears "wet", as if it might be leaking fluid. It's not much, just a little. Most of it is on near the bottom and near the UV joint that connects to the drive shaft.

I know this is a difficult question to answer without seeing it, but is some of this normal, or should I be concerned?

I had a Chevy Tahoe that had rear axle problems and it made a noise when I drove so I knew it was bad.

With this truck, I don't notice a noise, just the fluid on the housing.

thanks,

Check the lube level. If it looks to be coming out at the flange where the driveshaft attaches it is the pinion seal.

 

+1 check your fluid and keep it full. a minor leak won't hurt anything as long as you keep it full.

 

How does the fluid taste?
