Bolt torque setting help
Cleaned up the wheels and painted the calipers. What is the wheel bolt torque setting? I couldn't find it in the manual and did a search on this forum but also couldn't find it, or missed it.
I have OEM stock wheels on my 2007 3.0i 225 45 R17 I'm thinking 96# ? They are the 17mm head bolts Thanks, Last edited by doane2u; 03-06-2016 at 11:24 PM.. |

Pretty sure it's 88, but wait for some other bids before taking my word on it.
I always go 85 on all my cars. Never had a wheel fall off. Never warped a rotor.

85-90 is fine but be sure to retorque after 100 miles or so

BMW TIS states that you do use a thin coat of engine oil on both the threads and the taper when reinstalling the bolts.
ONLY if you use new bolts you dont use lube. This is probably due to corrosion prevention and seizing of the bolts. (new bolts have an undamaged passified zinc coating that gets damaged once used). Personally I always use a very thin coat of copper grease on the threads, applied with a brush. (I don't reapply it every time when I install the wheels) The correct torque spec is 120Nm (+/-10Nm), so 88,5ftlb (+/-7) to be precise. Obviously never use impact wrenches

Thanks everyone for your quick input, really appreciate it. I always hand torque and I use a very light copper anti-seiz from a stick on the threads.

Man, I learn something new every day here. Is that copper grease available at local auto parts stores, or is that something that probably needs to be ordered?

Yes you can buy copper grease at any autostore. Either in stick or tube or jar....
You can also buy ceramic grease which more or less funtions the same, but I prefer copper grease for the wheels (I think over time it sticks better and leaves a better thin film and has better anti galling properties, but I use both extensively). Both are anti seize products. |

I've been using mine for 20 years on many cars I've owned and never had trouble with lug nuts seizing, etc. Mine is sort of a lip stick looking stick with a cap on it.

Yea, I never heard of copper grease until I read about it in a few threads here.
Gonna get me some. I've always used WD-40 on pretty much any nut and bolt, but then switched to Liquid Wrench Super Oil.

WD-40 does everything a little bit and none of those particulary good.
