Hey there, I recently had some work done to my rear differential (pinion seal & axle seals). After it was put back together I noticed there was a leak around the cover on the differential. I removed the cover, drained the oil, and put a new seal on. However, I noticed there was quite a few filings in the oil (I only had put about 400 miles onto it since the work was done when I noticed the leak). So I put the cover on, filled it up with oil and took the truck for a spin (about 10 miles). Got out and inspected the differential. I noticed that it was really hot. If I held my hand there for more than 3 seconds it felt like it was going to get burnt. Unforunately I am not to knowledge with this part of the vehicle, is this something I should be concerned about and have inspected or is it common for the rear diff to get really hot?
Any advice would be great appreciated, thank you
