Steering gear woes... Replacement options.

[Z48LT1]

CrackedHead, thanks for the pitman arm specs - a picture worth a thousand words and all that. Now that I read your first post again, I see I was alerted to the 10:1 ratio way back when. d'oh!

Anyway, glad you're enjoying your new steering.

Cheers - Gary

a 12.7 :1 G body box is 2.5 turns lock to lock so a 10:1 box at 2.5 turns will rub hard at full lock cause the wheels are turning more.

So if I read that right, you would remove the washers, put in a shorter spring, and drill the orifice out to .144?

SPRING - GM (5688037) - $4.33

I think what they're saying is that you have the option to drill out the orifices or replace the valve and spring and eliminate the washers.

i think the math goes like this. 12.7:1, 12.7 degrees of steering wheel rotation for every 1degree of pitman arm movement. all things being equal, i.e. internal steering stops. total movement of a gbody gear is 78 degrees and 30 minutes, or 78.5 degrees. so 78.5 times 12.7 equals 997 total degrees of steering wheel movement. divide 997 by 360 and you get 2.75 turns of the steering wheel.

if you apply the same math to the 10:1 gear you end up with about 2.25 turns.
