I just checked, 800 miles driven so far. Except for a tiny coolant leak
where the cooling fan sensor is welded and a bit excessive oil consumption,
it?s been driving and running just about perfect. With one exception.
A harsh vibration under accelleration. And not even hard accelleration.
always there, always stripping away the good feeling you get when you
get to drive your brand newly done project car.
Yesterday i fixed it!
I was going to adjust the rear axle backlash (a pain to do on these 10-bolt
axles). I wasn?t exactly enthusiastic, and procrastinated by checking the
prop shaft alignment, or ratger the pinion angle.
I noticed that the pinion was one degree high, which, of course isn?t ideal,
A degree low would be better. So, just to avoid the shimming of the axle, I
unbolted the lower link bars and screwed out the ends one and a half turn.
This amounted to a 3 degree change.
By the one change at a time rule, I lowered the Buick to the floor and went
driving. The vibrations were 90% gone!
This time procrastination really worked in my favor, the result is a car that
I can finally enjoy fully to drive!
