I had a loose stub axle so I took both sides out. Found two different axles in the car! The one on the left is stamped "J15" and has the backing plate for the lugs while the one on the right is stamped "F15" and has no backing plate. The one on the left had an unpeened nut at about 40 ft lbs of torque. The one on the right was the normal bear to loosen up after dremel-ing out the peened portion of the nut. The one on the right almost has too little rust...
It gets worse, the one on the left had the threads shaved! There was no apparent use of lock-tight on the retaining nut. The spline count is the same on both axles as the flange which hooks to the half shaft are interchangeable.
I have bigger images on my server http://www.lee-thompson.com/Z/StubAxle/ but the bandwidth is slowww.. I have 200K, 2M and 8M versions of the images.
Two questions.
Is the shaved thread axle useable with locktight on the retaining nut?
Where did these axles come from as they are differnt? 260Z??? Its been reported that the spline count is different for 280Z stub axles.
Thanks in advance for your advice
