ericem Posted September 21, 2006 Share Posted September 21, 2006 Hello my friends, time to do the brake pads. Now i have my fancy micrometer torque wrench and would like to torque my wheel nuts to the correct amount now that have one. So what should each nut be torqued to? Thank you!

tcspeer Posted September 21, 2006 Share Posted September 21, 2006 I use a 80 ft. lb. torque stick, and it ends up around 78 lbs. when I check it with torque wrench. The correct value I think is a little lower but not much it should be in owners manual. quote=ericem]Hello my friends, time to do the brake pads.

I wish i could find my owners manual, lost it some time in 1998. Link to comment Share on other sites More sharing options...
Wayne Boncyk Posted September 21, 2006 Share Posted September 21, 2006 My usual ROT (rule of thumb) is 80 ft-lb for alloy wheels, 100 for steel. That is close to mfr recommended torques for many cars, I think. Link to comment Share on other sites More sharing options...
tcspeer Posted September 21, 2006 Share Posted September 21, 2006 Haynes manual says 72 ft. lbs. for my 1997 Legacy wagon, I think yours would be close, I still like 80 ft. lbs. Link to comment Share on other sites More sharing options...
dmanaenk Posted September 21, 2006 Share Posted September 21, 2006 So why alloys should be torqued less? I always thought it should be other way around, and vaguely remember that subarus are ~65 steel and ~80 alloys.. ericem look at Legacy777 web site for a manual for a similar year legacy.

Manarius Posted September 22, 2006 Share Posted September 22, 2006 whats his website? http://www.surrealmirage.com/subaru 80-100lbs was what I always thought. I just put them on as tight as I can get them. I figure that's around 80-100lbs per nut. Link to comment Share on other sites More sharing options...
jamal Posted September 22, 2006 Share Posted September 22, 2006 So why alloys should be torqued less? I always thought it should be other way around, and vaguely remember that subarus are ~65 steel and ~80 alloys.. Because alloy wheels are softer. This says 67-70 lb-ft, which I haven't had any problems with. 80lb-ft is apparantly about the tightest you want because of the strength of the threads. I'll flip through a machinist's handbook at work tomorrow to see if that's true. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted September 22, 2006 Share Posted September 22, 2006 I used 65'/lbs on SSR alloys the day I went to the track with my WRX and checked 'em twice during the day. They never budged. Carl Link to comment Share on other sites More sharing options...
ericem Posted September 22, 2006 Author Share Posted September 22, 2006 So for metal rims what torque? Link to comment Share on other sites More sharing options...
Moodybluesr Posted September 22, 2006 Share Posted September 22, 2006 58-72 lb-ft. according to Subaru. I always err on the high side and torque mine to 72. This is for all Subarus except the SVX and some of the newer STI's I believe, wether steel or alloy. Link to comment Share on other sites More sharing options...
NoahDL88 Posted September 22, 2006 Share Posted September 22, 2006 Subaru's have crazy low wheel torque, i think the EA-82's were close to 52 foot pounds. if you over torque them, they tend to warp the rotors. Link to comment Share on other sites More sharing options...
Setright Posted September 22, 2006 Share Posted September 22, 2006 I go for 95 Newton Meters. What's that in your money? 73ft/lbs ? Link to comment Share on other sites More sharing options...
BigMattyD Posted September 22, 2006 Share Posted September 22, 2006 on my 96 legacy, the FSM states 65 +/-7 fl/lbs it seems low, but it works matt Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted September 22, 2006 Share Posted September 22, 2006 If you throw out the highest and lowest numbers from this thread so far, total all the other numbers and divide, I get approx. 71.6 . I see no reason not to use 70-75 ft/lbs and then just check the torque a few times, especially on new alloys. There is further discussion we could pursue as it relates to lug nut/rim seat profiles, use or not of anti-seize, nut thread engagement, etc. I think there is a page at www.tirerack.com that discusses lug nuts. be careful out there.

Setright Posted September 22, 2006 Share Posted September 22, 2006 Clean, dry conical surfaces. Anti-seize on the threads. Torque, drive around 200 miles, re-torque, sorted. I set my wrench a little lower like, 94Nm instead of 95Nm when I re-torque as this avoids over tightening. Link to comment Share on other sites More sharing options...
ericem Posted September 22, 2006 Author Share Posted September 22, 2006 why does this seem so difficult? Isnt there a known amount of torque for each bolt? before all i did was make each bolt tight as i could, so. Maybe i should just do that lol.

Wayne Boncyk Posted September 22, 2006 Share Posted September 22, 2006 Wow! I found a website that gives recommended torques for lug nuts based on bolt diameter: http://www.tirerack.com/wheels/tech/techpage.jsp?techid=107 I always thought that there was an issue with torquing alloy wheels too tight and causing local fatigue and/or deformation at the point where the wheel meets the nut, but the more I poke around for info, the less I see anyone care about that any more. Maybe with the nuts properly designed to spread the load over a greater part of the wheel, that's no longer a problem. Anyway, Tire Rack says to follow mfr's torque recommendations, but if you don't have those handy, then these torques should suffice. Interesting -- I always learn something here on this Board, although sometimes I have to go off-Board to learn it! Link to comment Share on other sites More sharing options...
Moodybluesr Posted September 22, 2006 Share Posted September 22, 2006 The most important thing to remember when tightening your lugnuts is to use the same torque on all four (or five, six, whatever) on any given wheel, especially if that wheel uses a disc brake. Uneven torque will cause rotor runout due to the disc itself being slightly cocked from the uneven pressure on the surface of the hub mating surface. Tightening by feel is not good for your rotors; always use a torque wrench. Even if it is a crappy torque wrench that is off by n% it will still get all the nuts to the same torque. That said, Subaru recommends 58-72 ft-lbs for all of their cars except the SVS (90 I think) and the newer STi's with the 5x114.3 (can't remember).

1 Lucky Texan Posted September 22, 2006 Share Posted September 22, 2006 The only other thing I can think to mention is, I have a personal habit of going around 2-3 times only bringing the torque up to spec on the last pass. I dunno if it's REQUIRED but I just can't bring myslef to go all the way to 65 on the first nut while the others 4 are loose. Carl Link to comment Share on other sites More sharing options...
jamal Posted September 22, 2006 Share Posted September 22, 2006 After I hand tighten them I'm usually within less than a full turn of spec, which I think is probably more than adequate. Link to comment Share on other sites More sharing options...
Olnick Posted September 22, 2006 Share Posted September 22, 2006 I have a personal habit of going around 2-3 times only bringing the torque up to spec on the last pass. Carl Excellent practice! Also be sure to tighten in an opposite/opposite sequence so the pressure is applied as evenly as possible while the wheel is being pulled in.

cookie Posted September 22, 2006 Share Posted September 22, 2006 I spin them on with a ratchet and then torque to specs. I leave the torque wrench out and set up and retorque after a day's driving. Then I put the wrench away and forget the wheels till next time. Link to comment Share on other sites More sharing options...
