G'day guys,
i was looking to shorten my diff and just wanted to know how i go about measuring it..... do i simply just put the wheels withint he guards and measure off from that using the guards as the source for spacing....or is it done another way.... also how do you ensure that the wheels are 90 degrees straight.. using a square is not really that helpful as you are assuming the floor it is being placed off is level..... any help would be great....
also what are good diff shops within Sydney

what kind of diff and what is it in.the easy way to get it 90 degrees is a straight cut in a cold saw and ther maybe a pipe locater on the flange about 20mm long,depending on what it is.

for around 90 dolars a wheel you can have the offset changed,more expense but definately easier.they will seperate the centre from the outer and move then reweld and machine for trueness.it may depend on what wheels they are but i have seen alloy wheels done and plenty of steel ones as well

yer i know that you can do that but i just bought the wheels recently for the purppose of getting the deep dish look.....if i did not have the intention to shorten the diff then i would have bought the wheels with the required offset.

are you a machinist or have you got a good mate who is a machinist?
If no just bite the bullit and bring it to somebody who has done it before .
If yes and you want to have a go at then how long is a piece of string ? How are the tube ends fitted ? How do the tubes fit in the housing ? Have you got a heavyduty housing or the old style ? Do the axles run true ? How straight are your tubes ?
I'm not trying to be smart but there is a shit load to know and the more you get into it the more you will learn .Like I said before a machinist is a real handy person to know because he will make everything run true .
goodluck

Hang the expense and get it done properly, you will be alot better off in the long run. Let the pro's do it, that way if it distorts alittle while welding it can be staightened in shop and you end up with a nice clean looking diff.
