If the wheel is wobbling then try just tightening the QR a bit - this usually removes any play.
Ever seen a QR fail? Shoots into the hedgerow and you never see it again. You don't need to, its now useless.

To be fair- for this to happen you would have to be seriously bending the chainstays inwards towards an ill fitting hub.

So in conclusion.If the dropouts or forkends are not parallel, ( hub faces not correct width ) there is a bending action put on the spindle through compression. The bearings run uneven and they wear quicker, or the spindle cracks.
If its the rear spindle cracking and fatigue fails, the next time you remove the wheel because the tyre is rubbing on the left hand chainstay every time you pedal hard, the spindle comes out in two pieces.
If on the other hand, the dropouts, spindle, cones and locknuts are in parallel, if there is a weakness in the QR thread, ( it can happen with out of alignment assy too ) and the owner gives the QR some jip, BANG!
I am hoping Dr Philip Whiteman of the Beacon RCC can confirm a QR failure on a Beacon RCC Sunday run about three years ago when a Beacon rider suffered the catastrophe about 1 mile south of Ragley Hall near Alcester.
The QR was never found and the chap phoned his brother-in-law ( a man with a van ) to get home. I cannot remember the chap's name ( I'm a Solihull CC rider ). We were returning from Craycombe cafe, where since an uproar with Kenilworth CC, cyclists have been banned.
So recently I noticed my back wheel was slightly wobbly, the rim is straight its the bearings which seem to be the problem. Is there anyway I could repair it myself?

So in conclusion.
You can have large muscles in your legs and bend rear spindles, or large muscles in you arms and over tighten QR skewers putting a squeeze on the bearings.
Either way, learn how to assemble a rear hub.
And finally.
A cyclist who has a perfect dropout/spindle alignment and NEVER suffered a bent rear axle;
has NEVER pedalled hard.![]()
You're overcomplicating things again Jimbo ... the anecdotes are great, but keep them in Cafe, eh?
