Corroded Wheel Stud Spacers

[stevesnaz]

I've bought new wheel studs because the spacers on my original ones were heavily corroded to the point that they were breaking up!!! I searched for it on the forum, but didn't find anything, so thought I'd mention it. Has anyone else come across this issue?

Looks nasty! I haven't seen it before, but definitely something to keep an eye on. Thanks for the heads up.

I guess they are original studs, although I still wouldn't expect to see corrosion like that after only 7 years! Nice set of new studs now, so hopefully no worries..

Lots of instances of corroded studs quoted on the American site Planet-9.

Seems to be more of an issue there.

Looks like salt corrosion

I thought that as well. The front studs were worse than the rear, however they were pretty bad as well...

Just wondering what you clean the wheels with?

Yeh a lot of plated steel on bikes go furry in the winter, I replaced all my studs on my R1 because it looked aweful, not too much you can do about it, although that said, I've not seen it before on care wheel nuts. I assume the plating has worn off and the whether and salt has got into them. If they are just furry it should just sand off and they will be sound underneath.

I have had this on my Boxster and my 996 almost identical

Nothing out of the ordinary. That said, I've only owned this car for a few months...

Common wheel cleaners are often quite corrosive.

Ive got a few similar on my Turbo, told the wheel cleaner was to blame. Can I ask where you purchased the new ones, there seems to be many types and prices out there?

On a related subject, does anyone know whether or not Porsche recommend lubricating the stud threads?

I also run a Golf GTi and note that VAG state explicitly that the studs should NOT be greased.

Porsche say:

"Always apply a thin coat of Optimoly TA (aluminium paste) on the thread of the wheel bolts, on the shank and between the bolt head bearing surface and spherical cap ring (under the head). Do not grease the spherical cap bearing surface of the wheel bolts that faces the wheel."

 

[Motorhead]

Interesting....thanks for that Richard.

In the past, I've normally used Copper Ease. Any idea why Porsche recommend an aluminium-based paste: are the steel studs aluminium coated? And, if they are, why are they corroding?

No doubt tubes of Optimoly TA are available at dealerships at a price greater than their mass equivalent in gold..!!

I always use copperease just on the threads-when I asked some years ago for Optimoly to use on the 964 we had then,it was no longer available.

Just found this on a BMW motorcycle spares site:

£6.75+VAT for a 100gm tin of Otimoly TA compound.

There is a good selection from Porscheshop.
