A wheel stud is still a wheel stud and a lug nut is still a lug nut and you tighten them up all even and tight enough to not come loose but not so tight as to damage the treads, break as stud, or wallow out the wheel. But you can take it to the Nth degree as usual. http://www.raskcycle.com/techtip/webdoc14.html I still use the elbow pop method on the front wheels and the snapping back on the back wheels. When something on my body snaps crackles or pops it's tight enough. But then again if it were me putting the heat tiles on the space shuttle I'd be using 16 penny nails and a hammer.

I'm not sure that include this one.. They also, as you may know, have 20 % of coupons that they send to your email almost weekly if you register..

Just tighten until your hands hurt was the rule <grin>. > > What has changed? > m A torque wrench is generally most accurate near the middle of its measurement range, and the one in the link has a max of 80 foot pounds. The other difficulty you will have with the torque wrench in the link is that it is 3/8" drive, and the lug nuts on your Sienna are probably 21 mm, which usually come in 1/2" drive. HF's 1/2" drive torque wrench is $19.99 so for $5 more, you will get a wrench with 1/2" drive that 21 mm sockets fit more easily, and the torque measurement you are looking for is towards the middle of its range. Here is HF's 1/2" drive torque wrench: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=239 Get a 21 mm 6 point deep socket so the wrench body will clear the wheel ornament. As far as lug nut torque, plus minus 3 or 4 ft lbs is OK, although it is probably better to go more rather than less. If you have alloy wheels, make sure the lug nuts are centered in the wheel holes so the wheel seats properly, tighten the lug nuts in a star pattern, and tighten to about 70 ft lbs with the wheel in the air and then tighten to 76 ft lbs when the wheel is back on the ground, using the start pattern when tightening the nuts. The reason for using the star pattern is to make sure that the wheel is seated properly and is not warped. The reason for using a torque wrench is recommended more now than in the past is that alloy wheels can warp more easily than the heavy steel wheels, and wheels in general have gotten lighter to reduce unsprung weight, which helps handling, and to save fuel, and over-tightening or uneven tightening can warp the brake rotor or drum that the wheel mates to. -- Ray O (correct punctuation to reply)

Just tighten until your hands hurt was the rule <grin>. > > What has changed? > m A 3/8 drive torque wrench will not have the capacity to tighten your lug nuts. It is going to have a useful range of about 20-ish to 45-ish foot pounds. This is a tool for far smaller projects than you intend to use it on. |
