Rear diff seal.

Noticed mine getting very wet where the driving shaft meets the diff. Is it a pain to change? If i can't get it done this week would it be okay to drive it? Have about 500k to do this week

Check the level to make sure there's enough oil in it at the moment. Whether its ok or not will depend on how bad the leak is. When you leave it overnight, is there oil on the ground the next morning?

Only a couple of drops on the ground. But can see where its getting thrown out from thinning of the drive shaft. Giving my mechanic a shout tomorrow.
