tranny swap question

[yuconfused]

well i have a whole list of problems.

1. my engine and tranny are dropped down about 3 inches in the rear witch makes my transfercase output pointed up. .

2. with the amount of adjustable lift i have 21in the angle at the highes point is crazy

3. i did talk to a driveshaft buiilder here in houston and he said that it would be possible to build one but i was looking at 12-1500 because it will require a double cardan at both ends.

4. the front axle will not accept the same gear the rear has. so my thought was to regear the rear to a 5.13 and put a 5.13 in the fron and change the gearing the the profab or scs drop case to get the final drive as close to the 7.17 that i currently have

the problem is that my inital build was not very thought out in terms of what i wanted as an end result. i have the look i want, but im sacrificing the function that i want as well, i hope this makes since.

thanks for all the replies.

the pinion angle is set to factory. i think that is a 90 ( but i could be smokin crack)

well, if you pull the steering nuckles off the front, and re-weld all your mounts, you could point that pinion angle way up which would help on the down low side at least.

well, without looking the truck over its hard to make suggestions and certianly they don't all sound easy or quick to do.

i am curious as to why your eng/tranny is at such an angle. i guess to correct the angle on the rear driveshaft. you could always fix the eng/tranny and run a 2 piece rear shaft. similar to what you would find in a stock long bed truck or 2wd CC with a carrier bearing.

12-1500 for a front DS with two double cardons is rediculous. get another quote somewhere else!

check out high angle driveline. i spoke to jesse and got some custom flanges made when i did my sas and he is very helpful and easy to work with. they do make a 18" travel/slip front driveshaft. i would think that could accomodate your 21" adjustable lift.

you then could add the double cardons at each end. high angle has some 42 degree double cardons. i think you could get all this done for under the suggested 12-1500.

what axles are you running front and rear?

i would look into changing the pinion angle on the front shaft. would take some serious work (rotating the knuckles), but would be worth it it sounds like.

[yuconfused]

i have thought about that as well ..... and its not out of the question yet. just looking for other ideas as well at this point. since no matter what i do is going to be alot of work, time and money.

yes the engine was angled to help with the rear drive angle.

Front axle is a D44 that has just about everything done to it. To make it as stout as possible, The reason a d44 was the choice is because when we first started this we didn't think we were going to run 49's. So we thought it would be plenty of axle and not to mention the truck will never really see any offroad. The rear is a d60

But again if i rotate the pinion angle i still have the gearing issue. That was something else that we over looked in the build. We never thought that would have been an issue. boy were we wrong

Houdini is the tranny that you have a 5spd? also how much do you want for it?

Thanks

yep....its a 5speed with 83k on it. i have had it on craiglist for a few weeks for 500 or best offer.



seems to me you could sell that D44 for a good little chunk of change and get a passenger drop d60 for the front and get the same gearing. you could always run the divorced case passenger side drop

[Inyourface1650]

Yep, thats what I'm leaning on recommending.
New D60
Then you can spend some time getting your new front axle right. Get the pinion rotated correctly, new gears, etc etc etc, and then just spend a couple hours swapping em. then you solve your front pinion angle, and you get your gearing back in order.



then all you have to worry about is the top end of the angle.

Your gonan end up spending the same amount of money by getting a new tranny and transfer case anyway. Not to mention new drive shafts. and you'll still have a D44.

Damit ...... I hate when people on the board say the same thing that my dad says. I guess y'all and my dad are right. damit damit. Thank you ,
guys very much for the help and input it is very appriciated. I will start looking for a d60 so i can start building it. Sure wish y'all lived local i would take y'all out for a beer.

Thank you,

Max

just so you don't run into a similar problem, you are going to have to change transmissions and get a diff t-case to run a passenger drop D60.

drivers drop (HP)D60s are harder to come by and wll cost you more(you could use your current transmission and t-case though). they are off of the older fords. anyway...you can only get up to 5.38 gears for the high pinion drivers drop D60s.

only way you will match the gearing you currently have is with a passenger drop.

some info for you on D60s you might like to read through

good luck!

If you aren't doing hardcore wheeling and that d44 is built I wouldn't change it personally. I would just go online and find a used np205 divorced transfer case ( they can have passenger or drivers side drop... the ford version has the drivers side drop. I picked up a 205 out of an old f-250 for my original plans for 250 in good condition). Then you can match your rear to your front gear and you will still have a good low range with dual transfer cases. That case has a good amount of front output drop and you could lower the transfer case slightly to improve driveline angles as well.
