can u put most power to rear wheels?

[tay]

hi guys i wont to put most if not all power to the rear wheels
is it just a case of changing the gearing in the transfer box or dose the gear box have to be changed as well.

1) You cannot vary the power distribution as it is controlled by the VC unit, and there is no way to alter this.
2) When you say “rebuilding” what is exactly wrong with it? if it is the cast iron case version and has shed teeth then forget rebuilding, the only value is in the casing & end plates, the transfer gears have been dropped by VW a long time ago as have some of the bearings, [xx(]
btw the last price VW listed for the gears was over 600 euros a pair, and yes they are matched pairs

lol just shows how much i no
i was told that the tranfer box off my syncro will fit the rallye gear box. i dont no how bad it is the chap i got it off sed it could do with a rebild i was hpoing that a gear box place could do it if i needed it

whots the vc unit?

[Chris S]

VC = Viscous Coupling,

the ribbed alluminium cylinder in the centre of the axle

as for rebuilding a transfer box, your local gearbox place wont have a clue where to start.

may I also direct your attention towards the search button at the top of the page.

can you not alter the bias by changing the grade of viscous fluid used ???to bring it in earlier ?

IMO there is a lot of mis understanding about syncro’s and power splits. syncros are frount wheel drive’s that can divert power to the rear wheels when thr frount wheels slip, beacuse the frount diff is driven directly from the gearbox, power is taken from the frount diff and sent to the rear.

ther are only two ways round this, 1) remove your frount driveshafts and see if anythign gives, or 2) get a frout wheel off the ground like this

soz about the low quality

[ld50]

why bother with the VC at all – weld it solid!

do keep chris’s email handy though, he should be able to get you a replacement

And what fluid do suggest using? and where do you suggest getting it from? []

btw, the VC unit diverts power to the rear wheels within 1/10 of a second or 1/4 of a revolution of any front wheel slippage, is that not fast enough for you? [:0]

how does it werck?
thats where the prop bolts up to isnt it could i do away with it?
if i made somthin solid to riplace it

Yes, it would wind up till something went bang and broke [}]

older landrovers discoverys were sods for it, if you put the difflock in and the surace wasent slippy enough they’d wind up then good luck getting it back out

If you want rear wheel drive, remove the front driveshafts, drive it and wait for the viscous unit to die. then remove that, fit some sort of spacer in its place then wait to see how long the rear diff lasts.

I never known anyone do this, it should work in theory, it would be interesting to see how things lasted.

to see a golf in a rear end power slide in the wet would be something i’d love to see.

if you do it please video it!
