Working on rear wheel repair and need to replace the wheel studs (P# 11571093) and lug nuts (P# 09595175).
I have checked every which way to get part numbers but can not confirm OEM equipment.
I see cheap zinc plated nuts and what appear to be a galvanic coating all with the same part number and a $10 dollar spread in price.

The original lug nuts have what appears to be a brass finish to them.

Does anyone have an idea who is selling what?

 

Checked Rockauto?

The brass/gold colour is just another type of finish similar to galvanizing, I don't recall the name of it
Check out McGard 64014 unless you need the ones to retain the hub caps, M14 x 1.5 mm
Dorman would be a good budget option

 

Little factoid tangent: It's unlikely brass. A common anti-corrosion finish for steel these days is zinc chromate or "yellow zinc" plating, which has a straw yellow color. It is applied electro-chemically. It has replaced hexavalent chromium plating, which has fallen out of favor since it was deemed a pollutant by the EPA. It is different from "hot dip" galvanizing, where a part is submerged in a bath of molten hot zinc metal. Yellow zinc isn't as durable as chromium, but it's more than good enough for a commodity item like lug nuts.

 

Thanks SteveROntario and mountainmanjoe, especially for the education on plating.

So would I just be paying dealer mark-up to get wheel studs and lug nuts or are these hard to fowl up items?
They are holding the wheel on so I look at them as a critical items.
Part of my concern over the finish is them rusting onto the wheel and not having a breaker bar available in a pinch to replace a tire.

 

Any parts dealer. I’ve never seen “bad” lug nuts

 

Just realized that there is no space behind the rear wheel hub to punch out the wheel studs,
- without pulling out the rear axle,
-- which requires opening up the differential.
Looks like another episode of 'Chevy Designers On Crack'.

Has anyone found a hack to get around the necessity of pulling the hub?

 

some vehicles you can grind off 1/3 of the head and that gives enough to install. some vehicle studs come clipped for this purpose. if you have the rear end i think you have...remove the axle shaft and hub...replace the axle seals and axle gaskets
