shaving diffs

[THICKNICK]

searched to no success

just tryin to find some info on shaving GQ diffs. wanted to shave and laminate diffs, they are 4.3s and rear is factory locker type.

was going to buy the brace kit (will try and find photo of it) but wondering if still useable if you shave the diffs, and what have you guys done about the drain plug.

your input would be appreciated,
if anyone knows any links could you chuck em up for me

there was a thread a while back.
Someone posted that they remove the lowest stud/nut that holds the center in and replace it with a bolt, this serves as the drain point.

As far as shaving goes you need to remove and strip the housing. cut the bottom section off the housing and weld on some flat plate. You are limmited by the mating surface for the center as to how far you can cut. (you will destroy the gasket face before you fit the crown wheel.

For the bracing, personally for the price (and i'm someone who could fab the braces easily) i'd just buy a brace kit from Superior Engineering.

What do you mean by "you will destroy the gasket face"?

[brad-chevlux]

the mating face on the housing where the carrier bolts on.

In order to take enough off the bottom to hit the crown wheel would mean you would have to cut though it.

probably a better way to say it, but i know what i mean.

Another shave...



Neither have drain plugs. The gasket face hasn't been touched at all either..

Not the best pic but you can see the 2nd one in the car here and the "Gasket Face" didn't need touching cause the pinion angle is best with the flat surfac (shaved bit) facing the ground.

so what do you do when you want to change diff oils with no drain plug

Pull an axle out and lift up the other side.


What wicked said, the pinion points up so you shave off the section parallel to the ground.


Where abouts are you located?

I was told this by a qld mod engineer- braced diffs are fine as long as the lowest part original housing is not lowwered or raised, ie pumkin.

I don't have specs but his word is good enough for me.

I shaved it anyway.
