I already knew all that, crankshaft pulley is out, so is oilpump spacer....this is all from AllData, I already have...., I needed to know, if I could get oilpan out, just lifting engine a little, and take grossbar member out?? So I don.t have to lift engine totally out, what a headache, with front CV axels!!! What the stupid design!!!!f I just could pull oilpump out, I could change timingchains, and pull heads off!!! Any other way to do this?? And, where can I get slingers fitting to my VK45DE engine?? Dealer the only place??/ i checked ebay, no luck !!=((
Expert:  david craig replied 13 days ago.

you need to lift the engine enough to clear the pick up and strainer, so no, it needs to come up a lot. as far as the slings, i will need to look around. theres no other way around it.

Expert:  david craig replied 13 days ago.

you really dont need the engine hoist brackets. if you have and engine hoist just use nylon straps and tie them around the manifold tubes. (after disconnecting the manifold at the pipe flange of course)

Customer: replied 13 days ago.
OK, that's what I though too, but,....do I have to take transmission /separate that from engine, or can I lift engine just couple inches?? Just to get oilstrainer bolts out, open oilpan of course, and do I have to take crossmember out anyway?? How about both CV axels?? Can I leave differential attach into oilpan??? I am going crazy here....all because this stupid oilpickup strainer.......
Expert:  david craig replied 13 days ago.

been there done that. its amazing what you have to do. you dont need to separate the tranny, but you do need to unbolt the mount. you can leave the halfshafts in as long as they're disconnected from the knuckles

Customer: replied 13 days ago.
I don't have to pull axel out from left side/driver site, which is inside oilpan?? Just unbolt left axel from engine site?? Or both axels from knuckle site?? I will change left axel anyway, my concern was, do I have to separate differential box from oilpan, or I can take it down with oilpan?? How about this long axel coming from rear into differential box?? And one more time, take out crossmember or not??
Customer: replied 13 days ago.
what did you mean unbolt tranny mount??? The rear one, just loosen it???
Expert:  david craig replied 13 days ago.

the halfshafts do not go through the oil pan. they go through the transaxle. the axle propeller shaft goes into the rear of the transaxle. that doesnt nee to come out either unless it give you more room. unbolt the tranny mount completely to give the engine/tranny assembly move room to lift.

Expert:  david craig replied 13 days ago.

taking the cross member out will give you more room, so i would do it if it were me.

Customer: replied 13 days ago.
I am doing this in a very tight space, about 18 inches free space both side of the truck...., plenty to go up, but...I don.t want to lift engine complete out, if I don't have to I would think 2-3 inches..., and then take crossmember, and stabilizer bar out, I should be able to drop pan off couple three inches, right??? Even the differential box is still attached into oilpan, am I right?? That damn strainer.....lots of problems because that strainer.....Got engine lift from Harbour Freight,....cheap $165 only, now I quess, I need to take it out of box,....to lift that damn engine 2-3 inches???? Happy Thanksgiving...., anyway.....=)
Expert:  david craig replied 13 days ago.

the oil pan should be able to be unbolted all the way around and seperated from the diff.

Expert:  david craig replied 13 days ago.

please accept the answer and leave a 5 star rating for me if you were satisfied with my assistance. its the only way i get credit for my help. thanks and happy thanksgiving to you also. take a break and eat some turkey.

Customer: replied 13 days ago.
Are you telling me that I can pull oilpan out/down and leave differential in place?? The differential box is attached into oilpan??? 3 bolts??? How about the axel inside oilpan?? It comes out, when I pull oilpan out?? It has to be freed someway, from which side of oilpan?? Thanks!
Expert:  david craig replied 13 days ago.

nothing goes into the oil pan..... you arent going to have bolts going through an oil pan, let alone axles......if its a cast oil pan, then there may be bolts that are attached to it, but not into it.

Customer: replied 12 days ago.
It is a cast oilpan, and I think differential box is attached into it!!! Just loosen the bolts, 3??, and leave differential in place?? my concern is the axel going thru to left side, inside oilpan, how do I pull that out, from where??? it is just not that simple......
Expert:  david craig replied 12 days ago.

loosen the bolts yes. the axle IS NOT going through the oil pan. its going through the transaxle/diiferential

Expert:  david craig replied 12 days ago.

just pull the halfshaft out on both sides, if you are worrired about it. it easy to do.

Customer: replied 12 days ago.
There is #16 "axle pipe" in you oilpan picture, and of course, there is axel inside, transferring power to driver/left side, my question is,: How do I pull that axel out?? From what side, and do I have to pull it out to be able to drop oilpan??? Yes, there is axel inside oilpan.......
Expert:  david craig replied 12 days ago.

what year is the vehicle?

Customer: replied 12 days ago.
I start to panic,...when Infiniti technician tells me there is NO axel inside oilpan....., getting nervous here,...that's why I always ask Jed,...or something like that, at least he knows...., my truck is FX45/2004.....
Expert:  david craig replied 12 days ago.

Expert:  david craig replied 12 days ago.
