Slack wheel nuts!

if a wheels been off i do them roughly 100km and then the following 2 days as they will work loose

shuttlespanker:
if the wheels have been off recently, they nuts should be checked regularly after 50 miles, as the wheel settles onto the hub and the nuts can work loose

most tyre fitters put a label on the vehicle to remind the drivers to get them re-checked after 50 miles

Our place operates a policy of torque nut up,put red pointers on nuts, then next driver takes unit to get nuts retorqued without vehicle going out on road.!!! Crazy system i know. :confused:

the bar is the biggest doer in of studs and nuts
over torgue as bad as under
you wont like this clean studs spray light oil on threads before refit

If wheel been changed nuts are torqued red pointers put on,unit sits minimum of 45 mins then they are retorqued.

Are they checking the wheels are seating properly with no rust/debris on the hub or wheel ■■ :grimacing:

have seen our mechanics put sstuds in one of those steam cleaning cabinets.

Never assume! Last time I had 2 front tyres fitted I watched the fitter leave the nuts rolling round on a dirty floor, he didn’t clean the countersink on the wheels and put them back like that, until I asked him what procedure his company had for re-fitting wheels, then he demonstrated the right way :imp: He also asked me to get them checked with a torque wrench after 50k

When my car is serviced and the wheels need to be removed the mechanic always washed the wheelnuts, cleaned the studs and countersink in the wheels then applied a smear of copperslip to the nuts, then tightened with a torque wrench. I have been using the same mechanic for the last 22 years and never had a wheel come loose!

Known as “cold torquing” i’m led to believe.

or as one fitter said to me about another company , the new thing for them is if the wheel nut indicators arnt lined up dont get a torque bar , just take the indicators off & refit them so they do line up :open_mouth:

If they’ve worked loose and they were over tightened then you’ll need to replace the wheel studs, as the steel will most likely have stretched and will continue to do so. Worst case scenario, they will sheer off or the nuts will be tight but the wheel will be still loose.

I have used the same mechanic for the last 30 years, who (apart from torquing), doesn’t do any of the above.

I too have never had a wheel come loose :slight_smile:

Our trucks have all been fitted with safetytrims on the wheels. These nifty trims indicate and lock a loose wheel nut. When I do my walk-round the only thing I have to look out for is whether or not a yellow indicator tab has appeared in the window on the trim. The good thing is that if a wheel nut works its way loose during driving, the Safetytrims will catch it, indicate and lock it in place so it cannot back off completely. They work really well…
Apparently the company that supply them have now decided to buy all the yellow Checkpoint indicators from operators that want to change to their Safetytrims. Ballsy!!!
