HI, yes they are a high pinion diff with reverse cut gears and by design are inheritly(sp) weak in Reverse.

Posted: **Mon Nov 26, 2007 9:44 pm**

"Apparently" from my research on ih8mud.com, the front diffs are fine, you just don't do recoveries in reverse. Its bad practise anyway, but something to keep in mind.

The guys in the states run bigger engines and even bigger tyres with no problems, provided you don't get aggressive trying to recover someone using your front tow hooks :wink:

Its not the diff thats weak really, hell, its exactly the same diff thats fitted with the factory lekky lokker. Like NJV6 said, its inherent due to design

Posted: **Mon Nov 26, 2007 9:50 pm**

Yep, very strong in forwards. 30% stronger by design I think over a normal one......

O and red devil - Prado ones are the same as far as i know - may be cheaper than an 80.

Posted: **Tue Nov 27, 2007 7:12 am**

cheers boys i just read the same info from i8mud too last night

i have the factory locker in my truck so will the prado one still fit. just thinking of the dollar.

Posted: **Tue Nov 27, 2007 7:22 am**

Must place a note in the truck "Dont tow PR if he is stuck in front of me", "USE the winch Jono"

Cheaper option

heheh

arrrr PR ill still get you out even if i have to turn the whale around. :wink:

Cool

it will happen again :twisted:

Posted: **Tue Nov 27, 2007 10:05 am**

Just check the ratios

Posted: **Fri Nov 30, 2007 6:07 pm**

They are quite a strong diff,being a locker one all 4 bearings are different also(very large bearings I might add $$$

)

what were you doing when it broke?

Posted: **Fri Nov 30, 2007 8:10 pm**

your 80's cruiser will be 4.1:1 ratio,i think all the prado ones are 4.3:1 ? so you will be looking for a cruiser one or parts there of. i have a cruiser high pinion in my spares pile but would cost you a stack of cash to have that...and you only really need the parts to pix yours..not the whole thing ?

Cheers wopass i was thinking of taking out the diff head and getting a new crown wheel fitted by the diff shop. as your right i dont need the whole thing and i not going to be going out in the hard stuff to brake it again.

shane i was backing up on a rope with PR stuck down a bank (Huge Hole) to check i was clear of a tree behind me and it went click click ( no bang).

i winched PR back to all four.

Hopping to get the head out monday.

Jono, there's a lesson to be learnt here, and I'm not sure the right person has learnt it yet. If my memory serves me correctly your not the first person to damage a diff trying to recover PR.

WHY DO LIFE'S LESSONS HURT THE POCKET ??

FITZY.

Posted: **Thu Dec 06, 2007 9:49 am**

Yea Fitzy

that wasnt quite a diff but a shared pinion :roll:

But it was a toyota aswell :lol:

Posted: **Fri Dec 07, 2007 6:55 am**

o bugger

nar when you look hard at the break you can see there are cracks that have eed there for a while. i was going to go anyway. im just please it went with me driving not the wife as she would have driven home on it and done a little more damage.

as for PR his time will come and all those toyotas ill be there to tow him home :lol:

Posted: **Fri Dec 07, 2007 9:12 pm**
