2004 Dodge Durango Oil Pan

My resource shows 5.0 hours for a 4wd and 3.8 hours for a 2wd, and that includes removing and replacing the intake manifold. I can only guess the manifold has to come off so the engine can be lifted so the oil pan will clear a cross member.

These times are "non-warranty" times, meaning they're realistic and account for rusty fasteners and other typical problems related to older vehicles. Warranty times are always less because dealership mechanics don't have to fight with those rusty parts, and they don't have to spend their time ordering parts or writing estimates.

I would ask why one shop is quoting ten hours to see if they're including more things we aren't aware are needed to do this job.
