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

"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 :D

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

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

Cheaper option

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.
