Trackday today and i could not keep the front left wheel bolts tight.

[PBCup]

Basically after about 10 laps of Donington today the front left wheel was loose. I tightened the bolts up went out again, came in after 4/5 laps and again the bolts on the front left were loose this happened everytime i went out. I was not torquing with a torque wrench but I was using a big bar are they were tight and just as tight as the rest of the wheels. The bolts did have some copper slip on.

Any advice appreciated.

Probably the wheel bearing, mine was doing the same and changing the bearing fixed it.

Don't use copper grease on wheel bolts on track.

Recently had the wheels painted?

 

[MartinR]

Aftermarket wheels with wrong size centre bore? Spigot rings needed?

am i missing something here? how could the bearing have anything to do with the bolts coming loose?

Excess heat or vibration could easily affect wheelbolts.

A fubar'd wheel bearing creates excess heat, a hot wheel bolt does mental things.

The wheels are Ph1 172 and have been refurbed.

Burpspeed had this issue (iirc)

Get some wire wool and get the paint out of the bolt holes. Where the wheel touches the collar on the wheel bolts if you get me.

I had a similar problem and cured it by running a tap down the thread - they were just full of 10 years of crap.

Could be loads of things though.

Wheel bearing normally undoes the hub nut too (pass side)

studs are better IMHO, the pure ones are the best of the cheap ones.

 

[PBCup]

I think for the sake of £130 I'll get the studs and the piece of mind.

Thanks for the advice guys. Won't be on track again till march time so plenty of time to get sorted.

It's all sky blue, just depends what time of year you look at the sky. Get that hairdresser's car to Oulton on the 24th you tart.
