Diff O-rings

[RC John]

My diffs have been leaking like crazy, so I decided to replace the stock seals with Kyosho P5 o-rings. They are a perfect fit, but I noticed they have a lot more drag compared to the originals. I put plenty of grease on the o-rings and outdrives when I put them in so it's not from a lack of grease.
My diffs now feels like I have 20K oil, instead of the 3k I put in. Will the diffs free up over time? If so, how long will it take?
