Why would the left axle shear off (while going down the highway) right behind the castle nut?
My '96 Corolla got a rebuilt tranny about 8 months ago. Last night the axle sheared off. I
was very lucky and did not end up in a ditch or worse. When I took the wheel off to see
what the noise was all about, the nut with a stub of the axle fell out of the hubcap. What
would cause this failure? The only thing that held the wheel on was the brake caliber
assembly.
