I am building a Book locost

I have a axle and when I got it, it already had the shocker & articulaing points welded on.
Just checked and found that it is toeing out by 0.35°

I am assuming that there should be a slight toe in but by how much ?

I am to adjust this by running beads of weld around the front, opposite to the welds where the mounts have been welded on

Also it has +0.35° camber out, so this will also have to be adjusted

Any one out there know what toe in and neg camber I should be looking for

Live axle camber is almost immaterial as it is changed by cornering forces as the whole axle being fixed to both wheels.
Setting up one axle on it own without taking into account the chassis and the front wheels may mean resetting once the car is built.
Dess Hammills book on suspension set up is a good guide and has I fo on live axles.
Toe could be influenced by packing out the rear hubs with washers.

Another vote for Des Hammill's book on suspension setup and brakes - published by Veloce http://www.veloce.co.uk/shop/products/productDetail.php?prod_id=V4207&prod_group=Performance Tuning & Modification&


Correct me if I'm wrong, but unless the axle is bent/damaged shouldn't the toe and camber both be 0...? I appreciate they'll never be 0.00000, but they should be near as makes no difference. Otherwise the half shaft inner and outer bearings would wear out pretty quickly wouldn't they?

It sounds like the axle may have distorted due to welding which is understandable and should be corrected if possible, although it would be easy to make it worse rather then better.

The shimming technique works to some degree with IRS and De Dion set-ups running jointed driveshafts as the joints can accommodate the angular change. I can't see how it would work on a live axle, again going back to the misalignment on half shaft bearings and or splines?

Live axles shouldn't have any toe or camber, all at 90degrees to axles.

Otherwise, it will eat wheel bearings with great regularity, and only marginally less so will it consume diff centres, by wearing out the inner diff gears.
