what size socket for wheel lugs ??

[pastor scott.com]

Tried to rotate my tires and found out the socket I need is not in my box. Is it a 21 mm ? nothing seems to fit. Whats the FP setting for the wrench ? Or should I bother. Heard that if you go to tight like with my air gun it might warp rotors

 

 

 

thanks Guys

18mm rings a bell for the lug nuts but then again, I may be thinking caliper bolts. Yes, it is CRITICAL to properly torque the lug nuts or you WILL warp your rotors. I use a 3 stage process. 1st pass torque to 70ft/lbs using the star method. 2nd pass 100ft/lbs. Third pass final torque to 140ft/lbs.

its most likely a 22 mm, thats what my '99 is. and yea, i heard 140 ft/lbs is where it should be.

Yeah, now that bob1527 mentions 22, that sounds more like it.

Bob and Bish are both correct. It is a 22MM socket and torque is 140 ft/lbs. I just did a rotation myself and noticed the tires on my 04 Silverado are about gone @ 16K miles. I'll be lucky to get 20K out of them. Is it me or has the General gone el cheapo on the OEM tires? My 01 got over 45K out of the stock Firestones.

22 sounds like it.

Wow I never thought Torque really mattered on these trucks. I've always just tightned lug nutz up like this

First Pass) Snug to the rim. Lower vehicle till the wheel makes contact still weight on the jack.

Second Pass) As tights as I could possibly get them by hand with a standard Wheel wrench.

 

I've never had any problems so far but, should I redo all of my wheels with a proper Torque Wrench???

i dont think its gonna matter a whole lot if its torqued exactly. i only recently got a 1/2" torque wrench that goes up to 140 ft/lbs. before that i would just tighten them as much as possible but not tight enough that it would be a problem getting them off. (which usually was more than 140 ft/lbs... im very muscular, haha jokes!)

22 mm and 140 ft lbs sounds right to me for what it's worth.

It is more about the sequence than it is about the total torque.

 

The problem is the newer vehicles have very thin rotors to start with. I'm assuming to save weight(fuel economy) and cost. If they are tightened improperly, they can and will warp. If you overtighten them (like with an impact), the same result can occur. Also, you should not have any weight on the wheel while tightening. Just have somebody hit the brake while you tighten them.

 

If it were my truck, I would redo all 4.
