Front Upper Control Arm Bolt/nut Size

[jonn]

I have discovered that the nut on the front upper control arm bolt (the one holding the arm to the body) has fallen off.

Does anyone know the size of the nut, as in thread size? I know I will need a proper 'crushed end' nut.

When I pull the car apart to fix it tomorrow I will have no transport to get the new nut so it would be good to know in advance. Attached pic showing which bolt/nut I mean. It's the one in the rear of the pic.

Cheers.

Same happened to me a month or two ago, Brad should have a spare one or two, I've only got a spare bolt now.

Good thinking. I have to drive past there tomorrow anyway.

Hey that looks familiar...

Also pays to check the bolt on the upper outer trailing position on the drivers side. Mine continuously works loose. No idea why.

I cant remember the size or pitch other than it is a flared nut ont he inside.

Yeah shamelessly stole your pic djr. The royalty check is in the mail.

The thread size was M12 * 1.25mm.

I'm willing to bet its because those bushes allow a little movement as they flog out. you need to replace them pretty regularly especially if you run extra caster

Yeah I was told it was most likely due to the bushes hardening in their old age, thus allowing the movement.

Not sure if the last couple of posts related to the first photo in the thread but if it did & for info the bushes in question were not by any means old. There is a thread on it somewhere which you can find with a search of the Whiteline part number for an R32 GtR front camber kit.

The photo is a few years old & may no longer reflect the product from Whiteline.

no its exactly the same I put in a set a couple of weeks back. how are the outers lasting? I've got adjustables inner and outer because its the ony camber adjustment I'm allowed to run

I replaced the outers with some bushes dimensionally similar but made out of nylon. They are a couple year sold now & are still fine.
