I had a trusted shop recently tackle this job for me and they replaced the IRS bushings and put on a new FRPP cover. I drove it several times and some decently spirited driving and never noticed any drips of any kinds but this past weekend I drove it fairly hard on some back roads and noticed today there were some drips. I'm thinking it's likely coming out the top vent due to them over filling it some. I hope at least. I don't want to have to take it back and be in the shop again but I will if it doesn't stop. My question is would you guys just watch it for a while and see if it continues to leak or would you go ahead and take it back in now. I'm somewhat sure it's coming from the vent tube b/c it sprayed the cross brace that is right behind the top of the diff cover and one drop that was on the ground was to the right side of the cover where the vent tube is. Has anybody else experienced this after a refill or should I take it back in now since I paid them a decent amount of money to do the work. It wasn't everywhere or anything but it definetly dropped two drips in my garage and the cover a little wet
