could use a little help!!
I have a 99 gmc Sierra 4wd. Iam currently having problems with it blowing oil out of vent on front differential. I have checked the level and it is not overfull. have also removed vent tube and made sure it is not partially plugged. I would appreciate any advise.

My differential seal leaked in my truck and front end was covered with oil.
