Ken,

As the horse power goes up with an 8.75 you reach the design limit of
what
the gears will hold. Especialy if you're a drag racer using large tires
and a
trans brake. So if your running in the low 10's your about reaching the
limit
of an 8.75. That is why you see guys running Danas in the faster cars.
With
a good set of Moser street axles, and a properaly set up 8.75, you
should never
have any trouble with an 8.75 on the street, or if your in the high 10's
or above your kool.

Earl

Earl,
When you say "weak gears" do you mean a design flaw or bad metallurgy?
Thanks, Ken

Sean,

Think about this, if it is loose, then the pinion can get a running
start at the ring gear, and hit it harder. Gee what will that do. It
will impact harder, and have a tendency to strip the gears. That is the
only real issue with 8.75 rears anyway, weak gears. So go get your pig,
and have someone else set it up correctly. The only reason he wants to
set it up loose, is because he is too lazy to take it apart again and
put the proper shims in the pinion.

Hi Sean,
Yes, I think he sounds shady.  I recently installed a sure grip so I was
in the shop manual and it has only one way to rebuild a SureGrip.  See
if he owns a dial indicator and torque wrench.  :-) Regards, Ken
