Outer Limits 4x4 Board

Hi, i have repeatedly snaped the rear axles on my 89 model 75 series cruiser, its stock except for a locker & 37's.
Can anyone tell me where to get stronger axles whether it's from another truck or an afermarket item?

Any help will be greatly appershated
Thanks for your time........


BTW... I did a search & couldn't find anything, there is proberly a thread out there but i can't find it so that is why i am asking......Cheers.

There are plans by PolyPerformance in California, USA to build 80 series axles out of 4340 alloy. They said they might consider making 40/70/75 or 60 series widths on custom made basis as the tooling is identical. No word on date of production.

Moser Engineering in Indiana, USA also has made them out of 4340 on a custom ordered basis. No idea on the costs though.

Where did your axles break? Pictures please?

what size tyres? if they are less than 42" you shouldnt be breaking rear axles.

do you have an autolocker? If you do this will be causing the breakages due to the strain it puts on the axle when it is locking in and out.

Upgrade to a manually activated locker and your axles will last alot longer.

Hi, sorry about the late reply,

Thanks for all the info, i will replace my Detroit locker & fit new axles.

Sorry but i don't have a digy camera.

Thanks again for the help.
Cheers

maybe a driving still issue perhaps?

i think Jack Macnamara in Melbourne is doing tougher diffs to suit. I know he's got an air locker for the 75. (just had one fitted in 1988 75ser)

Yeah I agree! You are an animal man. And stock ?? What about the excessive amounts of boost that thing runs??!!

I'll second that

How about running a rear LSD and haultech traction control. Cheaper then a manual locker and you wont be putting as much strain on those axles

Axles break because they are too weak for what the driver wants to do with them. Changing lockers or driving styles is just masking the problem of weak axles. I'd be searching for some custom axles.

an autolocker will break axles alot easier than a manual locker due to the engaging and disengaging an auto locker does.

unless hes running 42" tyres the rear axles should be strong enough.

He runs 37 inch MTR's

Cruisers commonly break rear axles if the wheel bearings are loose or it has a bent housing.
