Het guys,
A while back there was post on warped rotors, with reccomendation for dealer to always use T wrench instead of air wrench. Didn't think of it in time recently, when i had wheels rotated ,so, can I re-torque mine using star cross pattern with wheels on ground or do I have to use the jack? Thanks!
Subscribing... When I rotate I use an 18" ratchet and snug them up while its up in the air, then tighten them in the criss-cross pattern when its on the ground.
if you get them stung when in the air and do the every other one till there tight then set it down then torque it down in a star pattern you'll be good.
i always put them on hand tight in the air, then let the jack down a bit so there is some weight on the tire and get them good and snug.
then i let the full weight down on the wheel and torque them down.
in your case, i'd just put the torque wrench to them on the ground.
if you find one that just makes the t-wrench click without turning, back it off a bit and re-torque it. the go around the full pattern one more time before walking away.
the idea isnt just to make sure there is *at least* 150 ft-lbs, but to make sure all of them are *even* and as close to 150 ft-lbs as your equipment allows.
if your shop used a torque stick on his air gun, you may find that they are all pretty close and pretty even. thoes torque sticks are a mechanic's best friend, and the owner of the vehicle's as well.
nothing beats torquing them by hand though, that is by far the best way.
You would normally think that anything that has factory recommended torque specifications and the dealers are using impact tools on, you could have a legitimate complaint but I doubt it would do any good.
The wheels can be seated with tires off the ground by snugging the lug nuts. Once the wheels are seated you can set the vehicle on the ground and do final torque. All you're doing with final torque is properly stretching the studs so the threads lock together and the nut doesn't loosen. The trick I use to snug the lug nuts is to give the tire a gentle spin and use the socket wrench to stop it. That little bit of spinning tire momentum will snug down the lug nut pretty good and you won't have to try to hold the tire by hand while you snug the nuts.
The other trick I use is to find a shop that really cares about doing things right and let them do it for me. Much easier then doing it myself.
