back up into the drive way that way it's easier to the oil leaks, lol
i know what your getting at and i think between the 2 on an extreme angle that parking nose up and a$$ down would be best because of where the oil sump sits on our engine, but that's just a guess on my part as i have no working knowledge of that half of the 3.4L v-6 motor in our trucks, and pray i never have too.
but backing away from the finer points , i don't think it really matters all that much either way....

Ok here is the deal. The gears in the differential are weaker when going in reverse. If you are trying to recover someone with a tow strap hook to the back of the truck that is pulling and if at all possible to the front of vehicle being recovered. If you are climbing a steep icy driveway Pull in. This is because if you loose traction on way up(tires slip on ice) then grab traction(sudden halt) then is less likely to damage the differential then if you reverse up the hill. It is harder to climb(heavier throttle more strain on parts) then it is to go down(less power used).

seems like it would be better for the trans as well,
but that said, how real are the dangers of exploding your diff from pulling someone from a snow bank in reverse?
seems very unlikely to me, it would seem as if something else would give before you damaged the gear teeth in the diff. it's self.
just speculating, as you pike man are the guy would know, lol
whats the deal, then? like 50/50 chance or like it would have to be worse then anything you have ever seen kind of stuck? just a ball park est. on how likely that scenario is....
x2... Never recover in reverse.

I can't give exact percentages as every recovery is different and maintenance of every vehicle is different. I do know that in every training I have received that is what they have said. I have also watched a few recoveries performed that way and it isnt always the gears that give out but on Jeeps they like to blow the U-joints in their knuckles up front so I guess for us likely to do a CV. I have also seen two blown rear diffs from recoveries this way.

lol, cool well that's good enough for me, i guess i have just been lucky over the years and need to avoid doing that in the future, it's one of those things i probably have done 50 times at least and never thought anything of it, well i haven't broken anything yet either, so maybe that's why, lol
huh, well that's embarrassing, some wheeling 101 i didn't know about, guess you learn something new every day then! lol
thanks guys and thanks for putting it into perspective, knowing that you've seen it happen a few times is good enough for me to avoid at all costs, if can be helped.
cheers
I've seen in person a bunch of blown Jeep u joints so I just don't do it even though I no longer own a Jeep. Hell, I never even wheel my junk so what do I know:shrug:
oops!
oil sump question ..
was curious if the driveway has an incline and there is option of parking nose up the driveway or backing up/reverse upthe drive and leave it overnight nose down the driveway, is there an oil draw benefit one way or the other..
I saw something online about toyos used off road oil starving the engines if they climb a certain sustained incline or ??

lol, not getting much help are ya buddy, lol
here's a flow diagram of the 22re, the oil pan looks to be almost the same shape as our motors so i'm assuming they have the pick tube placed in the same place, again not our engine so can't be 100% but it looks as if it would be better nose down butt up.....

THX buddy !
the g/f house has along steep drive way - I park on the street when I am not spending the night and switch my parking front or back in 1st - I will back it in / up from now on unless I hear of 3.4 being much diff than 22re

I don't see the advantage in that pic for going butt up. It is just a hand drawing. Maybe someone should take a pic of the oil pan if you are really concerned.
Honestly though, I feel like it would be better to pull nose up. Especially if it is slippery, going up is where you need to feather the gas and concentrate, so I would rather be going forward. Backing out, just put it in neutral and slowly let the brakes out to go down. I think that would be easier than feathering the gas and looking backwards to get up it.

i dunno i think going up hill is always easier then going down hill, esp if it's icey, as you always have more control when going up then when going down.
i feel like if i start sliding down my driveway in the mornings ice i would have better control to try and swerve or give it gas to recover if going down forward.
and to be honest i don't think it really matters at all which way you park,
unless you live here
and like i said i'm just guessing here, i truly don't know , but i do know that the where the oil pan is located as i have changed my oil a few times and can plainly see where it's at on the engine, also it makes no sense to place the pick tube in the shallowest part of the pan, so it just makes sense that in the most extreme circumstances that you would want to park with all of the oil to the deepest part of the pan.
and from that hand drawing you can tell Spatially that the tube is located in the center of the deepest art of the oil pan , as you rotate that view to a true sideview the tube pick up moves to the center of the pan.
again i'm talking out my butt here as i don't really know, just guessing from the information i have found, so i could be so far off base it's not even funny, lol

I've also wondered which direction would be the best way to park on my driveway but my concern revolves around the suspension. Since my truck sits in the driveway 5 days a week I'm wondering if that constant force on the downside causes the suspension to sag. Since that bothers me, I switch it up every week. Problem solved.
