Hi there
Does anyone have any experence with factory cable difflocks that came out in 60, and 70 series cruisers.
How good do they work,and are they subject to horsepower limitations?
Any info would be appreciated.

Cheers

no personal experience, but I have heard of them twisting axle splines
between the locking mech and the side gear which prevents axle removal and requires cutting open the back of the diff housing and cutting the axle to remove the diff head. This is with a 350 chev

Never heard of the spline twisting with the cable lockers.

I have two trucks with this setup. Both are still running the factory engines. 12HT and 13BT. They both run 36 centipedes when 4 wheeling.

The only issue that I have come across is the front CV's are two week for the front locker if you want reliable use. The rear axle tends to pop the little studs that hold the drive flange onto the hub. Gotta keep making sure the littel suckers are tight.

The lockers are a 5 spline dog clutch. 4 or 5? Which means they don't lock in a responsively as an ARB or 80 series front locker.

But they are bloody tough. Never had any damage in the diff itself. Have pulled them in going hard nuts too.

We also ran them on the tough dog cruiser for a few winch challenges. That had a bored and stroked 350 with the cruiser A440 auto. Never had any trouble there either, apart from the endless supply of CV's. chromoly CV's are the way to go.

This type of diff lock is also very easy to adapt an air ram engage system to.

Might wanna steer clear of the HJ61 diff lock with the 12HT diesel. Ratio of 3.7:1 Kinda makes going slow out of the question.

yeah cheers for that ,I'm just looking at some different options for my winch truck than the usual ARB's. Power wise they only have to take a lexus and 35 simexs

Yep - I agree Damn Rotorua Safari

Jeez boys, this has always been a problem with front lockers in 60 and 70 series cruisers. Don't know about the 70s, but a hilux cv is stronger than a 60s cv, beacause the flat spot to pass the king pin bearings is not as big on a 'lux. Just bite the bullet and pays your money for some chromolly numbers from Bobby Longfield in the US.

I think I have any C.V. issues sorted, but only time and abuse will tell
One of my friends has been running 70 series prado cvs with good results so far in a lj71 cruiser with a front locker.The dude is normally pretty good at destroying cvs and he hasnt broken one yet.

I thought the LJ71 cruiser was the prado. LJ71's are those small cruisers with coil suspension and hilux engines? What year are these trucks you talk of?

They are also smaller than the BJ and HJ cruisers!

Sorry he has a lj 70 cruiser the one that came out as a bundera in austrailia.
The cvs we are using are out of lj71/78 and kzj71/78 prados and have a lip cast around the outer edge of the cv
You need to grind a bit out of the housing to get then to fit though.
Apart from these cvs all hiluxs and cruisers up to 80 series run the same size cv joint.

As far as I know ,all the Prado's from 1990 on, all came with the same front axles and CV as the Landcruiser 70 Series.from 1990.>
As in the PZJ, HZJ. Quite a bit stronger than the earlier cruiser's and Bundera's.

I heard 3.0 prado's had stronger cv's than 2.4 2LT Prado's (bundera's)....

Is this a Myth?

how can prados have the same length axles as a cruiser when they only run a hilux sized diff head?Its only the cvs that are interchangable.
Both 2.4 and 3 litre prados from 1990 onwards have the bigger cv that I'm
talking about.
Cheers

Classic discussion

All i think of when someone says prado is the light weight IFS shopping trolley version of a landcruiser

Sorry, i just do!
