Rear Axles.

Post by Trigger_Andy »

Anyone ever swapped an A-Body 8 3/4" Axle into an Aussie Charger? I see the A Bodys come in at 57 1/8" Wide Drum to Drum but Im not sure what the Chargers are? I'll suspect they are wider?

I might be getting my hands on a very rusted out RHD rusted out Barracuda, but it looks like the rear axle is still there. Which would make it a Suregrip.

the spring perches are in the wrong place by an inch or more
you could move them or the springs..
suggest moving the perches is best bet. the axle is a little bit shorter so with the right wheel offset and tyres you will get a bit more tyre under the back
you do end up with 10 or 11 inch drums
benefit... parts easy to get from rockauto
drawback the 9 inch drums on there originally used to lock up as soon as you looked at the brake peddle. 10 or 11 inch will potentially be too big


mid 60s B body is about the same width axle as the original and it has spring perches that are only 1/4 to 1/2 inch out so it bolts up

no idea if you can use the same prop shaft length but if the US axle has a small dodge yoke and many many did and still do, it would bolt up to the original prop. but as i say prop shaft length wise not sure.....

60s B body axle is basically a bolt in provided you don't go mad on tyres and check the depth that the trans yoke goes in

i.e compare axle centre line to tip of the pinion yoke on both axles if they are within a 1/4 - 1/2 inch you will probably be ok yoke at trans usually sticks out a bit past the bellows on the old style seals, to allow in out movement as suspension winds up and down...

if the back of the joint Bananarama! the bellows when yer mate jumps up and down in the boot you will rip it off.

flat seal could be used or get prop shortened

if the yoke doesn't go in far enough you risk trashing the transmission

the whole stability of the rear end of the gear train is dependent on the bush in the end of the tail housing keeping the yoke centred. to stay centred it needs full engagement of the splines across quite a length of the output shaft

that bush in the end.... think of it doing a similar job to a crank main bearing..... clean yoke smooth seal surface decent bush decent seal....

the new axle will be worth more if it is a plate/clutch sure grip than if it is a cone sure grip

i think cone sure grrips were a 70s thing and may ony have been in 8 1/4 rather than 8 3/4 . the cone ones are supposed to be great for snow and greasy roads not ideal for drag racing, and dependent on type once worn out can't easily be rebuilt when the centre case is worn its scrap

Thanks once again Dave. :)

If I get my hands on this RHD FB sitting in the field I'll flog the axle or swap it for a 65-67 B Body one then. :) Im sure the Sure Grips in these Barracuda's are the Clutch type, but could well be wrong. :D

I know Jerry’s 69 C Body Fury had an 8 3/4 Cone style rear end ...

that makes prefect sense....you would expect them to be in the Posher cars, less likely to be gunned from one set of lights to the next and supposed to be slightly less abrupt in the application of torque biasing mainly working better with less traction at both tyres... snowy rainy muddy etc

might have phased em in or, it was a who can supply what and when thing, cone are Borg Warner designed dunno if they had anything to do with the plate/clutch version.

if it was a separate cone and side gear one its a prime candidate to be rebuilt and live again..the other type with the i piece cone and side gear it makes more sense to buy a new one..

BW still made little versions of them in oz but the company has changed hands so many times BW - British Tyre & Rubber (BTR in receivership under Grant Thornton for years)- Spice Axle Australia - Dana Corp and the dana corp site doesn't list any anymore, so i guess the factory went down the tubes along with the rest of the Aussie car industry...their T5 T56 etc gearbox factory closed i know that
