Was cruising around in 4x4 today then got under the Bronco to change the trans fluid. I saw gear oil leaking out between the front driveshaft and the front diff. I cleaned it up real good and drove around again. Got back under afterwards and noticed it was bad enough that it was actually dripping! Here's my question is this called the front driveshaft seal and how hard is it to change? I could always just drive around in 2wd but winter is coming up and I'll need this fixed ASAP. Thanks for everyones help on this forum it has been a great experience!
