1JZGTE Posted June 12, 2009 Share Posted June 12, 2009 My wheel nuts are rusty and the wheel studs could do with a clean. I used a wire brush to clean up the wheel studs. Question is, before whacking the wheels back on, would I be doing any harm by slapping on some grease or maybe spraying some WD40 on the wheel studs and wheel nuts or is this a no no as the grease / WD40 will assist in the bloody things coming off at high speed? Sorry if it sounds daft... Link to comment Share on other sites More sharing options...
Guigsy Posted June 12, 2009 Share Posted June 12, 2009 its probably a daft question.. but not one that i know the answer too Not as daft as the guy we had once that said "can i put wd40 on my brake disks to stop them rusting up" Link to comment Share on other sites More sharing options...
trinitom Posted June 12, 2009 Share Posted June 12, 2009 never use any kind of lube on wheel studs!! Link to comment Share on other sites More sharing options...
pistonbroke Posted June 12, 2009 Share Posted June 12, 2009 Copperslip mate, thats what I've used in the past. I only use it because I've seen others do it, so I followed suit. Link to comment Share on other sites More sharing options...
downimpact Posted June 12, 2009 Share Posted June 12, 2009 (edited) Me and Brother use Copper grease having been recommended by others. Also due to not being able to get wheels off before without a big hammer. We've done numerous track days and drift days between us and never had a problem edit - only use a dab per stud. Edited June 12, 2009 by downimpact to add a small amount (see edit history) Link to comment Share on other sites More sharing options...

matthewm1965 Posted June 12, 2009 Share Posted June 12, 2009 I always use copperslip in the studs/nuts. Also a thin smear in the mating faces between the steel hub and the alloy wheel centre. Having witnessed a tyre fitter bend an ally wheel when using a sledge hamer to remove it! Link to comment Share on other sites More sharing options...
1JZGTE Posted June 12, 2009 Author Share Posted June 12, 2009 never use any kind of lube on wheel studs!! Ok from the responses I now understand that I shouldn't use grease / WD40 and instead use copperslip, but why not use WD40 / grease etc. that's what I'd like to know Link to comment Share on other sites More sharing options...
SteveC Posted June 12, 2009 Share Posted June 12, 2009 WD40 is primarily a water repellent and would dry out. I can't see any problem using a bit of grease on the threads instead of Copperslip. That said, I also tend to use Copperslip. I remember having to drive down the hard shoulder of the motorway with a flat tyre because I couldn't undo wheel nuts (threads hadn't been lubricated). Fortunately it was only in a Fiat Panda, so the replacement wheel and tyre weren't very expensive. Link to comment Share on other sites More sharing options...
Andy Blyth Posted June 12, 2009 Share Posted June 12, 2009 I'd personally never use any kind of grease or lubricant on wheel studs. The reduction in friction provided by the grease will alter the relationship between torque on the nut and tension in the stud. This means that when you tighten the nut to the rated torque, the stud will be under a lot more stress than you expect. It's a gamble to how close this stress will be to the yield stress meaning snapped studs and lost wheels. Keep them threads clean and dry! Link to comment Share on other sites More sharing options...

garethr Posted June 12, 2009 Share Posted June 12, 2009 I have always been told (and I've seen it in some car handbooks) that wheel nuts or studs should not be lubricated. Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted June 12, 2009 Share Posted June 12, 2009 Just use copper slip. Its a supra so the studs are more likely to snap off first before the nuts have a chance to come undone:) Link to comment Share on other sites More sharing options...

Need4Speed Posted August 23, 2009 Share Posted August 23, 2009 A very small amount of copperslip on the thread only. The nut is locked by the face that contacts the rim. And use a torque wrench. Link to comment Share on other sites More sharing options...
pete_TT Posted August 23, 2009 Share Posted August 23, 2009 Yeah i use copper grease and a torque wrench too. Think its 114NM. Link to comment Share on other sites More sharing options...
Scott Posted August 23, 2009 Share Posted August 23, 2009 I use copper slip. I doubt anyone actually torques their wheel nuts so ignore that bit. Never ever over tighten them though, as hard as you can on a one handed pull with a 10" ratchet is plenty, put a couple on that way then use your wheel brace to get a feel for the torque by registering where the brace is, loosen it off, then tighten it back up. If your wife/girlfriend cannot undo them then you have gone too far. Link to comment Share on other sites More sharing options...

If you've got a torque wrench, use it and if you've got a socket set but no torque wrench, buy one (and not one of those cheapo bendy bar types) it's an investment in your car.

Scott Posted August 24, 2009 Share Posted August 24, 2009 I doubt it will work like that unfortunately. The torque settings are for stock wheels with top-hat nuts. The torque setting will be slightly higher for the 60 degree nuts on most aftermarket wheels i would have thought. Link to comment Share on other sites More sharing options...

Yes, it would appear that around 20% more torque is required for the 60° cone type nuts. There's some good info here about wheel nuts, studs and spigot rings.
