Hi FABO. Can anyone tell me what caused this deformation on the spindle bottom where the large bearing meets?
Spindle deformation is caused by what?
- Thread starter jawbone
- Start date
-
Bearing bind or a nut that was loose and allowed the cone to spin on the spindle.
So just the incorrect preload could cause this?
Giving it some more thought... probably the seal chewing at it ...
Are those '70-72 E-body spindles? Because if they are, using the 73+ inner wheel bearing will do that. The bearing has a larger inner diameter so loading the bearing pushes the seal against the spindle and backing plate.
It was advertised as a 73. Confirmed the measurements for a 73 spindle. Has me at a loss as to what could chew a groove that deep. If it can't be seen, there is a deep lip on both sides.
That has to be an inner wheel bearing failure. The seal rides further back on the shoulder, and the inner race should be seated against the lower section of that. That looks like where the roller for the wheel bearing would be, so maybe a roller backed out of the cage?
Still problematic, you're definitely going to need to dress that rough spot out, and then check and make sure that groove doesn't interfere with the location of the inner race for the wheel bearing.
The wheel bearings were replaced but so far the seller in not saying why.
Doesn't really matter at this point, the spindle is chewed up. So regardless of what caused it, you'll need to make sure that the new inner wheel bearing can ride where it's supposed to and everything fits properly.
So right, Was not planning using it. Sacrifice to the God of Speed.
