Sharp clicking from passenger rear half shaft area.

Leave it alone..........next time if it becomes a nuisance.......put some anti-sieze on the axle spline.....that worked for me

Where did you find the nut? I called all the "big" parts houses and they don't have anything (back ordered) for 45 days.

Is this/could this be a hardware store item? If so, do you have size specs?

Thanks!

I (Finally) found a set. Davies Corvette (corvetteparts.com)in Davies Florida. They have them in stock #646030 for about $25 I got both sides for new washers, nuts, star and cotter pins, delivered on Thursday.

I swapped them this morning before all the college football begins. I torqued to 190ish. I went for a quick ride on a route that typically gets my rear axle sounding like a Rice Krispy treat. So far all quiet but I'll take it out for an extended ride this afternoon.

So, other than new, what makes the new set quieter than the original set that appears to be in good condition?

Look for Dorman Spindle Lock Nut Kit 5101 at your local auto parts store.
They run around 8 bucks each

I wonder if the loose nut caused my right rear bearing / hub assembly to go bad... didn't notice noises until this summer - less than 75k miles. Put it up on stands and found the right rear wheel would move quite a bit.

Finally pulled the rotor off last weekend and found the nut was just more than FINGER TIGHT!

There is a huge amount of play in the hub assembly on that side compared to the other, and have a replacement in hand... hopefully next weekend I can get it off!

I agree that the loose nut contributed the failure.

After thinking about it more, I'm not so sure. The nut simply retains the half-shaft, keeping it engaged in the splines. The hub (and bearings) are held in place with the three bolts to the suspension system.
