I tried searching and couldn’t find a thread about this so if there is one can someone send the link? I dont mean to make a new thread on something already discussed. So I recently discovered some drips of gear oil under the rear axle and it looks to me like its coming from the pinion seal, is this a common problem or am I wrong and it could be coming from somewhere else? The leak is nothing that serious but I like to prevent fluid loss over time if possible. Also I could replace this myself if necessary. Thanks in advance!
