FR Strut/ camber adjustment

[kkrup62 at hotmail.com (Karl Krupke)]

Right... the adjustment is the relationship between the strut and the hub 
carrier, the eccentric bolt is merely a means of setting the adjustment.
    I use the eccentric to line up strut and carrier to the mark I scribed 
earlier, then tighten the other bolt (non- eccentric) to spec, then rotate 
the eccentric bolt out of contact with the flange on the strut, then tighten 
IT to spec.
    The compression of the strut's bracket onto the hub carrier holds it in 
place, NOT the eccentric bolt. So the eccentric doesn't have to remain in 
contact with the flange once the adjustment is set (and non- eccentric bolt 
is torqued down). Loading on the strut/ hub carrier joint is going to be 
linear (more or less) along the line of the strut, rather than from the side 
(which would create the most leverage to 'change' the adjustment, the force 
would be perpendicular to the joint).
    So if the strut bracket and hub carrier are nice and clean, bolts in 
good condition and torqued to spec, you're good to go. I usually wire brush 
the hell out of 'em then wipe on a thin film of light oil; 3 in 1 or WD-40 
-ish to prevent rust.
