Have '13 3500HD. For 25,000 miles so far have been doing oil and filter changes, tranny filter changes, and tire rotations myself. Figure I have saved hundreds of dollars so far.

Question on torque on lug nuts....stupid one probably. ...manual calls for 140 ft lbs torque. I usually just torque them manually. Any downside to using sears impact driver with up to 200 ft lbs torque? Bad idea?

I don't trust just pounding the lug nuts on with an impact. Damage the stud by over tightening and you can have a real issue. I always use a torque wrench.

I agree....always use a torque wrench. Back in my younger days, I always rattled them tight with an impact. Then I had my front wheel come off while driving. By over tightening my lug nuts repeatedly, it stressed the studs, and they broke off. Lesson learned. :eek:

If I'm not torquing them myself, I always watch the tire guys to make sure they are torqued properly by hand. Been years since I had flat tire along the road but the last time it happened the tire monkeys torqued the lugnuts so tight I couldn't break them loose by hand. Don't wanna have that happen again!
