SOURCE: can i remove oil pan without removing engine 1984

Yes, you can remove the pan without removing the engine. You may have to remove anything preventing you from getting the pan out or you may have to disconnect the engine mounts and raise the engine enough to get the pan out.

How take oil pan off 96 s_10 based

I don't know liter size of engine? 2wd or 4wd? You safely raise and support the vehicle, where applicable. Drain oil from oil pan. Remove bolts from oil pan. You may need to use a thin putty knife around gasket edge of oil pan to loosen. Depending if 2wd or 4wd there may be a different procedure?
There are safety issues working under a vehicle. Safety is your responsibility.

2003 Chevy Trailblazer Cannot seperate differential from oilpan is there a trick?

You have to remove the oil pan first - the diff stays up in the body until you remove the pan, then the diff comes out.

How to pull down oil pan on 2003 chevy trailblazer

Guessing you have the 4.2 liter engine and are trying to figure out how to "release" the oil pan from the engine block as it is on there even though all the oil pan bolts holding on the transmission bellhousing (4 of them) are out and you have everything out of your way like the compressor and differential etc. Take the 2 bolts that were holding the oil pan to the engine block. There are 2 "jack screws" on the oil pan. Take those 2 bolts and put them in the "jack screws and tighten the evenly in to remove/loosen the oil pan. Hope this is what you were talking about as this is kind of a tricky one if you haven't done one before.

I am changing the drivers side carrier housing! I pulled the wheel, and c.v. axle, I removed all of the bolts holding the Housing to the engine, and removed the driveshaft. It will not fit through the hole...

you will need to remove the steering rack,frame crossmembers,and motor mount stud nuts.then CAREFULLY lift the engine up by the oil pan with a jack.The jack must be positioned on the passenger side of the oil pan.Or you can remove the oil pan.

Need to know once u have taken all bolts and parts looose on 2003 trailblazer front diff. is there anything going thru oil pan connecting left and right sides

yes. the passenger side axle goes through the engine and into the diff. there's a retaining clip just like on the driver's side axle i'm assuming you removed from the diff. you'll have to just pop the axle loose to unseat the retaining clip and you should be all set.

2003 Trailblazer EXT - replacing the front differential. I have it all torn down, the differential loose, all the bolts out of the oil pan but the oil pan will not come loose. Help please?

it's possible the gasket could be sticking. give a few taps with a hammer just dont go crazy on it, i think it's aluminum. hit it on a well reinforced part, or use a block of wood to spread out the blow.
