Hi, can someone confirm that’s a leak from the pinion seal. If so, how bad?

Thanks!

Thought so,
Reason I looked… getting a vibrating noise that area.

Happens when stopped, after releasing brake. Definitely sounds like the rear center…

Pull the driveshaft and inspect both u-joints for free and easy movement. That mileage range is usually the end life for the pinion end u-joint.

Check for movement of the pinion shaft. As the bearings wear, there will be lateral movement which will cause the seal to eventually fail.
