2002QCFX4

I noticed a few oil drips on the driveway and decided to crawl under to see were this is coming from. I found that the oil pan looks wet around alot of the seal. I re-tightened the oil pan bolts, and used a engine degreeser to clean it up to see if I can see exactly were it is coming from. My question is, if I have to drop the pan and replace the seal, can it be done in the truck? Is there enough room to drop it with out having to remove front housing, cross member, or raising the engine? BTW its a 5.4, 4x4.
