rear axle

hey, im planning to run a cossie rear diff (lsd 3.62:1) on a de-dion chassis (but i dont get my chassis till end of march :cry: ) just a question about the rear set up really, bob just said that the cossie rear set up was bigger but i think that it doesn't make that much difference :?: when i was reading through some posts on the locost site they were saying that they had to use half shafts at the rear with a de-dion? what are half shafts and why do you need them? surely you can just put in the cossie rear diff,drive shafts and hubs? any further pointers here would be helpful thanks

ALSO.....

im having a bit of a problem getting the wish bones off the cossie rear setup




do i have to undo these bolts (forgive the sexy slippers)



or the hub nut?



its been doing my head in for the past week its a job that could be done in half an hour (i think) but forgive me im new!

Can't see yer pics!

The halfshaft talk was referring to your sierra shafts, one and the same!

I think without the aid of the pics that you have a shaft and arm off each side still complete???

If so, you need to undo the hub nut on each of them, which will be fun!!!

In your top pic, you can see the diff. Either side of this is a hald shaft. This is the metal bar with a CV joint at either end. The other end of these half safts bolts to a hub which is sandwiched to an upright which is connected to the A shaped trailing arm.

You will need to remove the uprights and trailing arms and replace these with the de-dion tube.

right just before i pop off to work, i have a compressor that is 2hp with a 100 litre tank i think and a pneumatic socket gun that fits the big nut on the end, a have a big stilton as well and a vice, would the compressor be powerful enough to remove it if u had the rest clamped up.

I have found the only successful undoing route to be to put the wheel flange of the hub in the vice, with two studs against the top surface of the vice to prevent rotation, and do the vice up bloody tight, then undo the nut with a big bar and extension tube (scaff pole!)

Seconded. After ripping the top off my work bench I took mine to work. Their steeb benches are fastened to the wall. the 500mm handle on my 3/4" socket had a 2m tube passed over it. I lifted myself off the floor before the nut cracked. They are on tight.

just remember those nuts are handed cant remember which is which though

near side nut is left handed

omega0684 - 16/1/06 at 07:43 PM

is it the drivers side (right) does up to the right ie clockwise, and the left hand side does up to the left ie anti-clockwise
