What is the best method to remove a rear diff from a brumby?

im needing to change the diff to suit the gearbox i put in.

I had a shot at it today but got stumped by the pins holding the driveshafts on. They just wont budge! have only soaked them in wd40, are there any other tricks to getting them out? i have removed in the past front driveshaft pins easily enough, but these rear ones are a mongrel.

cheers

Use the Toonga method.. FBH and if that doesn't work.. get a bigger one

yep it works 99% of the time but the other 1% nothing will remove those rear pins or shafts from the diff and as I recall the whole diff and shafts had to be replaced

add heattt....loads of boiling water works okay. Or a blow torch, i can imagine getting boiling water up there will be a pig haha.

is it the pins on the diff that wont come out or the ones on the hubs? If its the diff pins, sometimes its easier to drop the whole diff out of the car with the driveshafts still attached.

Or do what I did when cup not come off the diff due to my pin punch STILL stuck in there - swapped in another diff and axle. Bugger the diff - I want my pin punch set complete again

the drills dont work all the time, caus the pins are hardened spring, and will snap some of the most expensive drill bits...hahahaha....

Will probably try the FBH method soon. Was thinking about drilling them out but now not so keen about that.

did have a blowtorch lying around somewhere... hmm

I normally go with what Alex has mentioned and remove the shafts with the diff.. once out of the car you can usually have better control on the pin punch. We have had many that seize either the roll pins in or the cv joint to the spline.. so when you go to put them back together

make sure you use lots of Kopr-kote and make sure the hole is aligned correctly

so finally got the pins out

now i cant for the life of me get the drivers side driveshaft of the diff or the hub! ive covered it in wd40, put heat to it, bashed it but the bloody thing wont budge!

any ideas?

Keep hitting it with a FBH and it will come.. you might destroy the cv joint but you should be able to pick up a cheap rear one
