I have an 05 R MT w/60k on it. At 50k I did all of my driveline fluids and replaced my collar and seals. I started noticing a slight gear lube smell when I'd come to a stop and have had a few drips on the ground. When I got the car in the air, I noticed the seam of angle gear is wet and the passenger side is wet. The fluid did not seem to be coming from the axle seal but there was a drip where the bearing collar goes in. I found a TSB on my year needing to get split, the inner edge filed and resealed. My question is, has anyone had that o-ring leak for the bearing collar or do I need to bite the bullet, pull the angle gear back out and completely reseal?
