I guys I am new to this I been reading for a few days now and haven't found exactly what i am looking for. I got 2010 se cc with 70k and I have been experiencing front diff issues for a few months. I noticed all my fluid leaked out and drive shaft and was popped out. Due to low funds and no mechanical experience I continued to drive the the truck, inquired the issue with the stealers and of course they say whole new diff. After reading I heard of popping it back in so i did that and smooth as butter back in it was. Drove it around the block a few times and still in. My question is will it hold fluid now that it popped back in. My front brakes started to pulsate pretty good and truck had allot of play in the steering but now that it's in seems to have improved besides I'm still getting a wheel bearing grind. Should I replace wheel bearings, and what should be the next step for the front diff? Hoping to get some good advice thanks.
