Dicky Ticker

I sorry I disagree yet again,crushed speedo drive on a front spindle probably cause by overtightening,secondly front spindle comming undone due to undertightening.
Both scenarios where +/- 5lbs could be enought to cause this. Industry standard would be about 45lbs so 40-50lbs by guestimate on a large nut or bolt head like a spindle is not a lot of pressure and for the DIY mechanic using a fair sized socket wrench or spanner very hard to get within the peramiters,especially if it has corrosion or burred threads.
