What is the proper recommended torque for lug nuts on the 968? How often do I need to check? Any help would be greatly appreciated.

Thanks

95 ft-lbs. I check (maybe too?) infrequently - once, about a week after I put wheels on.

We use 95 lbs/ft for the tech line at our DE events...Anchorman is spot on!

95ft/lbs and I check mine about once a month. There's always at least two lug nuts that are less than 95.

While we're on this, and without trying to be what I call a TPITA (that's a Technical Pain In The Ass), I feel the obligation to point out that the proper SI measure of "torque" is the Newton-Metre. Of course, more familiar to us, and correct for the "95" number, is foot-pounds. It's not "ft/lbs" and it's not "lbs/ft". Torque is not a "rate", it's a "force". Applying torque at a particular rate is what results in horsepower.



For another discussion of torque, see http://vettenet.org/torquehp.html.

Anchorman - I'd rather be technically correct any day! Press on...



So then what technically should we call it when we 'torque' a bolt to a specifice setting?

Anchorman's information doesn't "torque" me. I like it. I have three torque wrenches....aka tork in some venues.



For smaller bolts, I use a small, sensitive, dial indicator torquiing device. For lug nuts, WalMart might work. I save my Snap-on for more critical, less frequent work as I don't want to wear it out.

Harvey,



At the risk of yet again going somewhat off topic, I'm planning to do the sunroof motor torque check procedure described in the DIY section (it's averaged in the mid-seventies all "winter" here in Austin), and the procedure calls for a very small torque wrench, one that can accurately read 5 ft-lb. What type of wrench do you have per your description above that you use for smaller bolts? My local Sears didn't have one that went low enough. Thanks.

Sears should have several torque wrenches that measure in inch pounds. For example this one would work fine set to 60 inch pounds

If not Autozone or other car parts stores should have something similar on the shelf for $20. I used some cheap torque wrenches until they failed then bought three craftsman torque wrenches.

something to think about on the lug nuts:



the more times you remove them, the less torque they can hold - this is especially true of the factory nuts - that is why they are not allowed in racing



if you find that your nuts are losing torque (no jokes please), or if you've been removing your wheels more than twice a year, replace them - i'm not saying to replace them every two times - i'm saying that over 12 years, at twice a year, those things have been torqued at least 24 times - that's a lot



this is an extremely inexpensive and far too often overlooked component on performance cars, that can result in very bad things happening to you and your car if you ignore it

Really? Most interesting - and something I would never have thought of.

i know - most people don't - it's one of the first things that stewards look at though - too many wheels flying off the cars - it's not nearly so bad with steel lug nuts - these aluminum ones though really take a beating - the next time you ahve a wheel off, take a close look at the inside of the nuts, and look closely at the threads - i'm willing to bet you see tiny specs of loose aluminum - care to take a guess where that came from?

i can't resist....



i think they make a shampoo for flakes on your nuts.

it helps if you want to wear black.



okay. i feel better now going into the weekend.

The steel lug nuts allow a visual confirmation of sufficient thread engagement, which is pretty important as well.



The alloy nuts do not seem to like being taken on/off 20+ times a year. Bloody things get pretty brittle.

The small torque wrench I have I got off Ebay and it goes from 0-50 ft lbs or 0-70 Newton Meters. It's marked:



CDI (made in USA)

#5120

OC 242

12/91 (so it is pretty old, I hadn't noticed)
