Thread: Sheared wheel nuts

Probably over tensioning the bolts, tyre fitters rattle gun springs to mind

Under tightening will do it too, due to metal fatigue. Correctly tightened nuts or you are at risk. Light oil on the nuts when tightening helps a lot.

Do you have D2/P38a wheels fitted?

If not, and they're not supported by the hub, this can weaken the studs.

I've always been taught that oil on the wheel nuts is a big no-no, as the extra lubrication causes them to self-loosen far more readily than otherwise.
Just my opinion, others disagree

Hi scouse,
when I bought the car it had 19" wheels with low profiles on, bought it because of its great condition and got a set of standard 16" rover alloys after a couple of weeks it handled like crap with the 19"on.That was over 2 yrs ago wonder if the damage had already been done

Cheers

Dave

I support the other lot..
I use nickle antisieze but if its not available a drop of engine oil on the threads and a wipe with a damped rag on the chamfer of the nut then up to 100NM or 100ftLB depending on what rim its on

Lack of lube will cause the thread or the mounting face of the nut to bind up before the torque applied can create the correct tension in the stud. It is this tension that clamps the wheel to the hub. I have been lubing wheel nuts since I was a lad, I once had endless trouble with mag wheel nuts picking up alloy out of the wheels. A quick spray of CRC or similar lets you apply torque without it being wasted on friction and metal damage.

What loosens wheel nuts is cyclic forces from the wheel turning and the wheel moving a tiny amount each rev on the hub. Only the correct stud tension will stop this cyclic force. Lube the nuts and you will achieve it.

There is on going debate about this as well,there are many wheels around that are not supported by the hub with no issues.

The D2 studs are pretty heavy duty,much heavier than many other similar type vehicles.

in fact the D3/4 have thinner wheel studs than D1/2.
