ok guys got a big lift and complete suspension change in a sierra ute
what i want to know is do i have to rotate the diffs around to get the flange that conects to the tail shaft to be pointing more at the transfer case?

i know tht sounds confusing but help please

the front has been changed heaps to.

the pic is of the back its the 3/4 we have in mockup stage the boys have done more since then but its the best pic iv got to show the setup


cheers

If you're using the stock shaft, then no, don't change the angle as the uni's need to be parallel to work properly.

[ajsr]

you dont want to rotate the front diff unless you are going to cut and rotate the knucles as you will muck up the castor and it will drive like even more of a pig when you get it going.

[matty87]

ah k thanks for that fellas

so if the angles on my unis is to great best way to fix that would be to lower the transfer case?

[shep]

unless you have lots of lift i wouldent worry about it. i had 100mm lift in a swb
and the shaft angle was fine a lwb has a longer shaft and can handle a lot more lift. ya just need to watch the slip joint, both my tail shafts have spacers on them.

[matty87]

Ah k thanks shep

we have a fair bit of lift but should be fine in that case.

my 3/4 eats uni's like theres no tommoro, i have recently had some shims fitted between the leafs and the diff to correct the pinion angle a bit as it was way out with 2" springs and shackles, dont ask me why. Havent done another rear uni since. Feel free to pop in have a squiz if you need any help with it.

[shep]

i have greaseable unis and i keep the grease up to them.

[matty87]

cool thanks mister rocky. baker boy (cam) and netts (kieran) who are on perth 4x4 are working on it at the moment i might let em know get em to send ya a pm and check it out.

cheers mate

[matty87]

mr rocky your understimulated on perth 4x4 right?

[MrRocky]

yeah i kept getting kicked off, would have liked to keep the same name but had to change it like 5 times before they realised i was there for good.
man i hate that greybeard dude, i reckon i'd punch him if i saw him.
Let us know when you sort out what your doing with the old tray off the ute

[lump_a_charcoal]

Both my diffs are rotated, and I have no vibration issues...

[matty87]

ok thanks charcoal think iv opend up a can-o-worms hahaha

Mr rocky i hear ya he is a bit of a doosh.

that tray is yours for the price of taking it out of my front yard. its in really bad condition tho like rusted through at the front and cam took to it with an angle grinder to get it off the chassis it might be worth you looking at it first but ya can have it if ya want it. Cam may even take it over to ya if he borrows my ute and comes out to check out ya 3/4 setup. id just send him a pm or an email to
team-whysoserious-racing@mothfukle-engineering.com
about it to sort it out. ill let him know what i told you.

what suburb you live in in perth?

[MrRocky]

Im in ballajura near malaga but if you want i can come grab it and you can have a squiz at my setup at the same time. Im free most arvo's anyway.

[matty87]

cool yeah i think cam has ya mobile number he said he would try give ya a call tonight if not iv sent ya a pm with his mobile number i think he is free for most of the week.

[bakerboy]

hey mick i sent ya a msg, let me know when ya free and ill drop the tray off
