Can someone tell me how long a job it is to drain and refill the diff without actually changing any seals. I don't care so much about fixing the leak as I do about making sure it has fresh full fluid inside.
Do I have to take out all the bolts around the diff or is there a drain plug? Do I need any special tools?
If I have to take out all the bolts around the diff and separate the pieces, then do I need a special sealing compound before I put the two pieces back together?
Thanks in advance for any feedback.

With the car on a lift it is less than a 10 minute job to drain and replace the differential oil. If your dealer would not do that for you and just charge for the fluid and 0.2 hours time I would find another dealer. There are two plugs, both 14mm hex that need to be removed. They can be tough to get out, but if you spray them with PB Blaster and use a long breaker they come out. Take the fill plug out first so you're sure you will be able to refill it, then the drain. Some have drained them and then found they cannot get the fill plug out...then it is a tough job because you're kinda stuck without oil in there.
