Wheel Bearing/Hub Assembly For The 88 Fiero
As read in the September/October Issue of Fiero
Dickman recently released his new front
wheel bearing/hubs for the 88 Pontiac
Fiero. This front wheel bearing/hub assembly
was only used for one year, and the only GM
car to use it was the 88 Pontiac Fiero. The
original GM part was #7466939. A number of
years ago these bearings were discontinued
by GM. Leftover OEM 88 Fiero GM bearings
were also sold thru auto parts suppliers in
boxes with various vendor names on the
carton, but they were all from this same
manufacturer that supplied them to GM for
the 1988 Fiero production run. The supply of
these also dried up around the same time.
One company made all the OEM GM 88 Fiero
front wheel bearing/hubs in the late 1980's.
This company closed several years ago.
been two aftermarket versions of this 88
Fiero front wheel bearing/hub that have been
made in the last few years, with limited
success. The ball bearings in these
aftermarket 88 Fiero wheel bearing/hubs are
significantly smaller in diameter than the
ball bearings used in the OEM GM hubs.
Dickman's front bearing/hubs use tapered
roller bearings. which provides a
significantly larger amount of bearing
surface than ball bearings. Why did GM use
ball bearings? Ball bearing hubs have
slightly less rolling resistance and provide
a small gas mileage increase. This minimal
difference is negligible. Rodneys new
bearing/hub is a heavy duty, double tapered
roller bearing design that is quality
designed and built, and should last for many
thousands of trouble free miles. While not
promoted or marketed for racing use, this
bearing is currently being used on some 88
chassis cars in racing applications.
Feedback has been positive, with no
malfunctions. The other two aftermarket
bearings have not held up when used on an
88 Fiero in a racing environment.
There is a
good guideline for installation at:
Pricing is $159.99 each, or $299.99 per pair
which saves you $20.00 when you buy two. I
suggest that if you develop a bad
bearing/hub, buy and install two; if one is
going bad, the other one is not far behind!
