Good Parts Constant Velocity Joints (CVJ) - Winter 2010

Why Install CVJs?

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 ( is now selling. An email from Richard gave this explanation of them:

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 Nissan. 

The Nissan R200 differential requires two different sized axles with the longer one
 being on the bottom which gets installed on the car's right side.

The axles are made with rolled splines and are heat treated.

Hub face comes with slightly longer studs than stock.

The part number and welds around the stud has been discussed in the forums with the
"best guess" being from a Ford Taurus.
Here's the backside of the stud showing the weld

These will bolt directly to the Nissan differential with no adapters needed

OK.... let's get them on the car.
