Oil pump is toast and metal is everywhere... where do I go from here?
Well the oil pump in my 87 22R-E is toast. I just pulled it today and this is what I got 
:
Anyway, you get the idea. Needless to say, the oil pump, spline and cover need to be replaced, along with all the gaskets.
I want to drop the oil pan and there isn't much clearance between the oil pan and the front differential. My 88 FSM says to take out the engine mounts and lift the tranny about 1 inch. An online 93 FSM indicated that this should only be done with a 2WD.
I'm leaning more towards dropping the differential. How is this done?
Also, is there anything else that I should check after seeing this much damage to the oil pump, especially with all the metal that was broken off? I shook out grain sized pieces of metal.

i hope you have a good oil filter, otherwise you will have some major engine damage, thats the first one that Ive seen do that, it looks like it tried to seize up, is that a Toyota pump or aftermarket?

Does anyone have any suggestions about how to lower the front diff or is there a better way to drop the oil pan on a 22R-E?

OK, I assuming you dont have a lift, and your truck is stock.
First thing to do is disconnect the CV's from the differential. There are six nuts holding the CV shafts to the differential shafts. They look like bolts but arent, use a wrench and brace it against something for the differential side, and loosen the nut on the wheel side. Once those are loose, you should be able to, or be close to being able to pulling the CVs off the studs in the differential shafts.
Next remove the driveshaft from the front diff. There are four bolts with lockwashers. take all four bolts off between the diff and the d-shaft. Then pull the d-shaft off of the pinion flange (may have to pry it a little).
The last part is removing the diffential from the truck. first you need to jack the truck up and put the jack stands or cinder blocks on the frame (very important.) dont put them on the a-frames cause you could cause frame bending (I found this out the hard way). After that remove the front crossmember from the truck. Should be four bolts, two on the passenger side, two on the driver side. theres also the attachment bolt that holds the front of the differential up. Undo all those, and it should slide out straight downward. Next there are three more bolts that hold the diff on. There are two on the drivers side and one on the passenger side. Undo these three bolts and manuever the diff out and your done... it isnt the easiest manuevering it out, but its possible. IF the CV shafts didnt come completely off the studs, they will in this process, and when you reinstall it, as you put the diff up and in, you need to line them back up on the studs.
That should cover most of it, but this is all off of memory. If you want, PM me and I can give you my cell number should you have questions while your doin it. Hope this helps!

Hey Troy, if you need a hand let me know, I took the front diff out of my 93 when I had it. I've also got one brand new side seal from my diff that I never used. If you have any leaks it would be a good time to replace the seal. I'll give you a good deal on it
