Front End Alignment by Nissanman

This all from memory, but I'm only 65, so we all know how reliable that should be :roll: Readings from the wheel alignment machine: -

As you can see the camber on the RHS was up the putty as was the caster on the LHS.

Instruction sheet for the Longacre Camber Caster Gauge: -

  • 1. Rolled the car to a point on my driveway where the front cross member read level using a spirit level.
  • 2. Jacked up the front end and removed the front wheels.
  • 3. With equal height wood blocks placed under the lower control arms at the same place side to side, I lowered the car so the weight was placed back onto the front suspension.
  • 4. Checked that the front cross member was still level.
  • 5. The Camber/Caster gauge was fitted over the top wheel stud and magnetically clamped to the wheel mounting flange.
  • 6. I recorded the camber and caster values for each side at both full lock positions and dead ahead, 3 readings per side. This gave me the current settings and therefore how much I needed to adjust the degrees to get to my desired settings.
  • 7. Jacked up the front end and rested the cross member on jack stands.
  • 8. With the front suspension in full droop, I re-read the 3 settings per side which gave me a new base line on which to add the require degrees to get the settings back to what I wanted when the suspension was loaded. As you can see from the table, the camber setting hardly varied from loaded to unloaded.

  • 9. Loosened the upper spindle mounting bolts and inserted shims between the spindle and the chassis.
  • 10. Shims at both ends will adjust camber, shims at the rear only will adjust caster.
  • 11. I re-read the settings at the 3 steering positions with the suspension still at full droop.
  • 12. Once I had reached the required settings per side, I blocked up the front lowers again and re-checked with the suspension loaded up.
  • 13. Below and hold, after I had adjusted the angles at full droop, the loaded readings were brought back to the desired settings.
  • 14. I was mainly concerned about the camber settings, which I managed to correct, but the caster was also slightly adjusted.

I now know why the "technician" couldn't be bothered. It took me quite a few hours to do the alignment since all I had was 2 jack stands, 2 blocks of wood and a trolley jack plus my trusty Longacre gauge.

No turn tables and certainly no laser alignment tools :roll:

I had to re-tighten the upper spindle fasteners every time before I could check my progress.

It was gratifying to see the logic and mathematics I applied, resulted in a predictable and repeatable result.

Well, it worked for me! Nissanman, just trying to help. 1965 SP310 Engine No. G-93326 Car No. SP310-10817 http://nissanman.shutterfly.com/117 McQueen! He's on the road again!
