Live axle trailing arm bracket orientation
Hi,
Is the back of the trailing arm bracket meant to be parallel to the back of the casing, or parallel to the prop flange?
As they are in the pic, they are parallel to the prop flange - surely this is right?
Cheers,
Pat...

Parallel to the prop flange. If not the rear UJ will be running at a different angle to the front and it will vibrate.

Are the prop flange and the casing not parallel??

The axle is resting on it's prop flange in the pic, but the rear of the casing is on a slightly different angle.

I'm sure i read on the forum somewhere to set them equal with a spirit level sitting across two bolts protruding out of the backplate mounting
holes.

I don't have any protruding bolts from the back of my casing - it's an Enlgish axle.
Any further updates on this as I need to get these brackets welded on.
Cheers,
Pat...

Sounds like you have a 'Banjo' axle with the diff cartridge that bolts into the front of the casing?
I levelled a piece of flat MDF as a surface table and then rested the axle (with diff removed and hole facing down) on four spacers of equal height
(positioned equally around the machined diff mating surface.
I then measured where the axle brackets went and levelled them (using a spirit level or inclinometer) before tacking.
With the diff bolted in and the axle installed in the car the diff input flange is pretty much vertical give or take 1/2 degree.

Right, so if I I remove the diff and place the casing on a flat surface (it will sit on the studs that hold the diff in place) this is my datum line
and then the brackets should be level to the board as well.
I can see it not being far off the first pic I posted.

I wouldn't use the studs as a datum but instead the machined surface where the diff gasket was.

Yeay, got it now - can rest it on two pieces of chassis tube inbetween the atuds and on my build table.

A trick to hold the brackets on when tacking is to put any old bolds through the holes and loop a big cable tie through so it clamps the bracket on to
the axle tube. --- it was good enough for a few tack tacks.
If you want to clamp the brackets more posatively use a very big jubilee clip instead.

When I welded mine on I set the brackets on a stand that was leveled and then set the axle on the brackets . Aligned and leveled the two and the
weight of the axle kept everything in line when welding up.
