Constant Velocity Joints?
Every winter I try and pick one major
project to improve my car for both performance but, more importantly,
reliability. Perhaps by coincidence or perhaps it was a sign being sent to me
but there were two Forum members who had catastrophic rear axle failures while
driving this past summer. Typically when this happens the rear wheel falls off
the car and you lose all control. One member was going slowly through a
neighborhood, bounced off the curb and ended up on the grass by the sidewalk.
The other member flew off the road, ending up in a cornfield. No one was hurt in
either incident, though the cars did sustain additional damage.
Every suspension component on my car
has been rebuilt or replaced with the exception of the rear hubs and axles. In
addition, all summer I was bothered by a "clunk-type" sound that was coming from
the rear...........sometimes on the left, sometimes on the right and sometimes
not at all. My guess was either worn splines on the stock axles or not enough
grease packed in to the stock axles. I
was going to buy Goodparts' upgraded hubs and axles but an email from Richard
informed me that he now had new improved CVJs in stock.
The new stub axles on
the right are substantially more heavy duty
than the stock ones on the left
Below are the new Constant Velocity Joints (CVJ)
that Richard Good (www.goodparts.com) is
now selling. An email from Richard gave this explanation of
My new CV joint axles use the Nissan
inner joint. The Saab 9000 turbo outer joint will fit in my hub and in the
trailing arm but I chose to use a larger one for more strength. I have the
axle bars made with rolled splines which are stronger than a machined spline
and then have them hardened. All parts are new. This is a better design
than the first ones I offered which were made by a shop in Florida. And
they're less expensive. I can sell the new hubs and axles for $1498/pair to
fit the 5-bolt Nissan diff or $1598/pair for the stock diff or the 6-bolt
