Cummins quickserv is your friend on that. The procedure is there in detail. 500,000 mile replacement intervals. As far as access, that depends on your truck. If you can reach in with the front end still in place then get at it. Most can. There is a pin to insure correct placement. But be prepared, Rawze got one of the few that required 4 monkeys and a team of mules to pull it. Maybe he'll post a link to that one for a little schadenfreude at his expense.
