Period Decamber Mods shim up stub axle

[John A. Ross]

That was done by hartwell so I assume it was well tried and tested, however .... it was a quickie mod as the high pivit suspension had reall y really bad camber, if you do the mod then lower the suspension then the geometry goes to pot again

I have seen folks thread these but there must always be gap inside the cavity which is not how it was designed to clamp in and concerns me.

So yes it is a standard mod Bob, thes days i would sit the suspension on lowered springs first then find a distance for neutral camber so its only pushed a little neg when diving in a corner.

Sit the car on stands under the wishbones and on its suspension with say weight of full tank of fuel, put stub axles in and find a hight that suits first.

Then see if the camber needs adjusted and test remove material to suit keeping measure, then make padding washer to suit car.

Those washers used to sell as kits.

Perhaps Dave Lane might have original mod somewhere

I have the receipt for this mod in my cars paperwork collection

You've got me wondering now !!!!!!
Should l do this mod now or see what cars like when running? as stub axles haven't been fitted yet.
How good are results , was the 1\8" come about by trial and error ? how reliable is that figure?

Period Decamber Mods - Material removed from bottom face of stub axle and washer added to the top



About 1/8th removed off bottom where the vertical drop bolt for the stub axle assembly is fitted through I think was instruction

The stub axle can then pivot on the horizontal bolt

Then to make up the gaps inside the wishbone a machined washer was used as a gap filler to prevent the wishbone being crushed when rumped up.

The lip is only there to stop it slipping off when attached to the bone
