Unhappy Rear wishbones....HELP

Hi
Does anyone have a plan view picture of the rear wishbones fitted to the chassis. My car is sitting wrong and after hours of measuring I seem to have one of the rear wishbones back to front.

Perhaps this picture will make the orientation a little clearer



This is the nearside rear wheel, photograph taken looking at the back of the car .

If memory serves me right, the book states that the single arm of the lower rear wishbone faces the front of the car.

sorry to be a stick in the mud ronnie you have that wishbone on backwards. the brace at the hub end should face forward.

Talking Damn, blast & bother

Oh bummer

Thats another re-read of the book

All seems to line up well. I can't remember if the wishbones are made symetrical or if they are made with an offset.

If they are symetrical I would assume that the placement of the wishbone is stress related.

On a brighter note, at least they are just test fitted

Default Confusion

Unless I am mistaken the picture ( p74 ) is opposite to the text on p73.

EDIT. Check the Drg on page 10, arms are made symetrical if not you would need 2 jigs as upper front needs. Brace should be under compression when acceleration. Pic must be wrong. OOOOOOOOOOOOOOP's

as tsm says the stress from forward motion should go into the brace at the front down to the rear sus bracket. the design is intended to make the wishbone stronger in forward motion should you hit pot holes curbs etc.

my 2p if i read the book amendments correctly bonzo has it correct it says:
"the lower wishbones need to be installed with the cross brace angled from outside rear to inside front"
So are you guys saying this is wrong or am i being thick?

Default not really important

allow me to give my opinion on the matter.

The amendments state that the text (page 73) should be installed with the cross brace angled from outside rear to inside front. This corresponds with the picture on page 74.
But is contradictory to the drawing of page 10.

Either way, the brace is meant for the triangulation of the lower wishbone and it doesn't really matter how it is orientated.
However, it would look silly if you have the two mounted differently.
From the viewpoint of mechanics it would be logical to have the brace being stressed rather than compressed while taking loads (say driving). Mind you, I wouldn't like to sit in the car when the brace breaks, no matter how it was mounted.
