Thanks Spider.

 

My plan is to set the car up so its sat at ride height but without the offending wheel on.

 

Correct the camber whilst in situ on the car using the otherside as my guide - thats the easy bit.

 

Then remove the arm and bit by bit adjust the toe angle refitting after each tweak until satisfied using string alignment.

 

It doesnt have to be to the degree accurate.

 

Im sure there are quicker ways but after some time thinking it through - I feel this method suits me.

I routinely bend the arms, nearly every kerbside one I seem to pick up is bent.

 

I did make a jig for the press to do them in, but found that cumbersome to set up, so I tried them between 3 hardwood timber blocks and found this to be quite successful. I set the Arm in the press sitting on 2 timber V blocks, with the blocks as far apart as they can be placed, then the 3rd block in the middle to press on.

Before getting this far though, you really need a reliable means of measuring the arm so you can see just how much it's bent and checking your progress as you press it back. You also want a means of gauging it when in the press to see if you've gone enough at each go to re-set it.

 

This is the jig I made for measuring the arms for Toe and Camber Angles;-

The heavy steel block fits on the stub axle (very neatly !) and then the angles are measured from that with a protractor;-

 

 

I's suggest over-bending it for the Toe Angle and then shimming it on the subframe to bring it back.

While I did make a jig for measuring the Arms, they can of course be measured on car. You don't need to measure to the minutes of degrees, just be able to check that you have it Toeing In, then as I suggest when fitted, shim it back.

 

Hi Spider, what are the correct camber and toe angles ?

Hi Spider, what are the correct camber and toe angles ?

 

 

Camber is 10 +/- 10 and Toe is 00, 15' (or 1/40).

I generally bend the arms to give 00, 45' to 10.

0.040" of Shim between the Outer Bracket and the Subframe reduces the Toe by near enough 00, 15' (1/40).
