How did you all get this bushing out of the front diff cover? Everyone seems to have got it done pretty straightforward but I have been chiseling at it for 4 hours no to no avail. The lip is up all around and I can see a gap between it and the diff cover but it’s not moving at all. No clue what to do. This was supposed to be a one day job - I need to drive the truck home for Christmas tomorrow.
