Front Top Wishbones
 
Hi Guys,

Trying to work out the correct way the front top wishbones should be on the sierra uprights. Anyone have any pics?

The threaded part is at an angle to the two tubes, does the threaded tube point up or down to the upright.
The thread is offset from center, I am guessing reward mount to get positive castor?

Upwards and longest leg of the arm at the front

Perfect! Many thanks.


On the rear, the two intersecting tubes at the chassis mount, towards the front of the car?
Top one then mounted so its equally in the middle of the two lower mounts?

Many thanks!

I Carl,

As said in the book page 73 regarding rear wishbones:
"The lower wishbones need to be installed with the cross brace angled from outside rear to inside front"

The picture Fig. 5.32 page 74 shows the RH side of the car:

Then, you attach the lower points of the rear upright to the lower wishbone, and there is only one way the upper wishbone can be installed to fall perfectly between plates RU2 of the rear upright when in place.

Hope that will help :)
