CSX7070 Rear Suspension Rebuild

[CompClassics]

The rear uprights are formed sheet metal with a machined from billet bearing area and an adjustable spring mount that allows for camber adjustments. The front upright are forged lower castings with a pivot bearing for steering and a spring mount that allows for camber adjustments. The front steering arms are look to be machined from billet steel. I will post photos when I get a chance.

The reason for replacement was to replace these parts with original specification parts.

Might add the SAI clunk frame pic?
May help others in the future.

Another reason for the clunk May be the upper chamber adjustment cam bolt adjustment. The camber adjustment bolt to the spring eye was not particularly well thought out. The camber adjustment bolt and the spring pivot bolt are one and the same, if you don’t tighten the bolt enough it will not hold the camber setting, if you tighten the bolt to much it pinched the spring eye and causes the spring and the upright to bind during travel creating wear at the thrust washers and the spring eye bushing. Eventually the wear turns into slop and you lose Your camber adjustment.

Here are the photos of the right side rear and front upright......

Dang, I hate it when you have to do something just right.

There should be a sleeve on the upper bolt that goes through the spring on the front upright so when you tighten the eccentric it tightens against the sleeve not the spring if it’s binding against the spring the sleeve is not there.
