Actual rear-end flip

[cris well]

could you actually flip the rear end upside down (left drum to right side) and bolt it on top of the springs?

if you could, you wouldn't need any kind of flip-kit at all--just c-notches.

i've been thinking it might work.

[the_duke]

The housing for the bolts is different. you'd probably drain all your oil out cause your rearend would be upside and leaking out?

And if I'm not mistaken, you'd have 5 reverse gears and 1 drive gear if you flipped it your way.

[Restrorob]

Simply put, It Can't be done and driven down the street....

[scotts62]

no just buy the flip kit..

[SWEET7T]

As The Duke said, it would go backwards. You would have to put the truck in reverse to drive it forward... So nope

[cris well]

it would go the same direction--the only thing i see that would be a problem is the pinion yoke would probably be too high.

[panhandler62]

It *would* be reversed. All of the angles would be seriously out of wack also.

[texasfunk]

Yea. Just get a flip kit..if you want to go cheap..there's a guy selling the brackets by them selves for around 40..reuse all your old hardware..used em on my 89 no probs.

No the rotation of the wheels after the flip will pull the truck backwards instead of pushing the truck forward. The rotation of the driveline will not change, thus the wheels will still rotate in the original direction, flipping it will cause it to go backwards not forward.

[cris well]

wow, this is turning in to quite a discussion.

i'm not gonna do it but it still think that it would still go the same direction.

since the rotation of the engine is not gonna change it would be just like a propeller on a wooden toy plane. it's gonna spin the same direction regardless of the position of the plane itself--be it upside down, side-ways, whatever.

just think of the truck as the plane and the diff as the propeller. does this make any sense?

the only thing different is the ring gear is now gonna be on the pass side instead of the drivers side.

i may be wrong though--it's rare but it does happen, ha ha.

[lolife99]

I disagree with everyone.
I say try it and give us some feedback.

There are alot of members that ask questions on here and don't listen to the replies.
I say prove them wrong.
Take plenty of pictures.
We all like pictures.

Cap the vent hose so all the fluid doesn't run out.
Cut off and re-weld the shock mounts.

I myself would just get the flip kit saddles and shock extenders and be done.

Cris, I believe you're right. I became so intrigued by the question
I drew one out on paper. The diff would be driven the same direction.


I think.

So..everyone got me thinking..had to "test" this..I agree..I don't think it would go forward...I grabbed a bottle..and rotated it forward..if u flip it while it's rotation..it indeed rolls backwards. Although..I did it several times. Couldn't be sure. Lol

ha ha.

texasfunk, the bottle trick isn't a good comparison. that would be like turning the yoke around backwards.

think about a truck that was driving down the road and has rolled over in a wreck. the engine and trans is gonna be upside down too but it doesn't matter because it still rotates in the same direction.

now the rear end is upside down but the wheels are still gonna be turning the same direction as before it rolled over.

anyway, i'm not gonna do it--just daydreaming.

who has those brackets for $40? is it a board member?

I'm with you, on this one. Makes no difference. On the other hand, if you took a Corvair rear end (rear engine, remember?) and turned it around and mounted the engine mid-ship, you'd have to flop the ring/pinion to get it to "act right".

[cris well]

you guys are right.

i figured out what texasfunk meant by spinning the bottle and flipping it--i was doing it the wrong way.

i was flipping the bottle end to end, not side to side.

[texasfunk]

Lol..I was like..hmmmm...I went to the shop an had an axle laying around...had to try it again. It indeed goes backwards. Lol..now let's put that to rest! I'll see if I can find the link to the flip kit for ya

Just reverse the rotation of the engine and you will be good to go........

Even if it would work, the rear axle isn't designed to run upside down. It would burn the bearing up eventually.

A marine cam should cover that !

[the_duke]

I had to wait to say this after the discussion...


































I thought I was wrong, but man, am I'm glad I'm right.

:LOL:

^^what he said^^

Nothing else matters...

[BigBlocksRule]

I had to think twice about it, but the wheels definitely reverse rotation. If you have a truck with a posi rearend on jack stands and drop the driveshaft, you can spin the tire on the passenger side clockwise, normal direction for forward movement. Rotate that axle 180* and direction for that tire is now still clockwise, but it's now turning towards the back of the truck...reverse.

Even if that didn't happen, you'd probably starve the pinion for lubrication, plus all your diff fluid is going to run out your vent tube.

[FMBL]

There was an episode on Extreme 4x4 a couple of weeks ago where they did flip the rearend for a rock crawler. They did say that it would change the direction. If interested you might look it up and see if there is any recap that might explain what they did to correct everything.

[GCncsuHD]

As stated before,
it would rotate the wrong way
would need to plug the vent
and vent the plug
pinion bearing would not be lubed properly.

You "could" flip a 3rd member axle like a 9" or a Yota, or one of the old Eatons, and leave the 3rd member right side up, but not sure if everything-bolts, axle tubes, etc would line up then.

That was with doing what I mentioned, flipping the axle, but leaving the 3rd member in the correct position so it will rotate correctly.

The perches and u-bolts are cheap enough, do it right.
