Sears locally just has a mechanic and torque stick. I had to ask them to hand torque them and you'd think I asked for their first born son. No more sears store for me.

I checked afterwards when the tires had been put on with 100 lb/ft torque sticks. Usually they were almost 100 lbs and some lugs were higher substantially. They don't go around and around star pattern to evenly tighten with the torque sticks. They just crank up one and then another and when all five have been hit--thank you. That'* why they get uneven tightening.

My torque wrench is 35 years old. It seems to be on. I'll check with the mechnic up the road who will have a professional model at home... I'll compare readings.

Doctors double check their instruments before they sew someone up. Are they ****-ups, as well? That was kinda harsh. Please try not to come across so tough on people.

I torqued my wheels after that last guy, they were close to the 80 he said.

Hella good point...

I retorqued all of my lugs before I left for my Vacation, after a rotate and Balance at Goodyear, and found the lugs to be on the money...

Both of my cars at one point had tires from Wally world, I watched them do everything.... They hit the lugs with aht torque stick, lowered the car and hit all the lugs with a torque wrench, parked the car and then sent me along my merry way... we pretty much never hear of them having much trouble..

Try not to offend people so much, weather or not you intend to do so, it sure comes off that way... Minimum wage Idiots?? Nice one

on my ssei they were terrible, massive shaking comming to a stop. on my eighty eight I purchased the most expensive rotors at RICEHQ, and they warped within 2 months, to the point where the whole car shakes bad from them.

What exactly is the problem with using a torque wrench? They're accurate and easy to use.

Jeez, we're supposed to be a bunch of car guys here. Act like it!

Damn, I always tightened the lug nuts by hand, first when its up and then when its on the ground, no torque wrench or anything. No warpage except for the front right but that was there before I did work on it. Need new rotors anyway...

Thats is a great way to break a stud off.

Thats what I do. My tire iron won't fit on the lugs with my rims, so I went out and got me a half inch drive breaker bar and deep socket (3/4'* I think). Been using that with good luck for 6 months or so...until I get a torque wrench
