wrong tool for the job. ![]() Posted by Snowmobile [Email] ![]() ![]() ![]() In Reply to: Cordless vs corded impact drivers, Dan ![]() |
corded or not is not the issue. I know some people only use a gun for this, even to reinstall, due to speed... but it's not the best way to do it.
I first walk around the car with a breaker bar and crack each bolt. My breaker bar is a 3/4" drive 4' long inch thick deal I got at Princess Auto (Canadian HF) for $50. Great investment! It doesn't matter what the tire shop did wrong before, corrosion (we're salt belt), etc, those bolts will crack loose with minimal effort.
Then I jack the car, and swap the wheels using a corded impact gun. Any gun will do, but I hate having batteries wear out, and this one cost me $30 on sale. It is not high torque and will not remove most fully torqued wheel bolts, but it has been perfect on other suspension components. Another great investment! Some people hate cords and are ok with batteries so they should get cordless.
Finally, I lower the car, walk around and hand torque each bolt to spec in the proper pattern. I use a simple cheap lever/dial style 1/2" drive torque wrench. Cost maybe $20.
It's pretty simple, takes little extra time, and I know everything is perfect in the end. I usually measure brake pad thickness and clean wheel bolts as I go.
I can't imagine buying a $600 impact gun unless I was going to take on many other tasks that actually needed it. You actually shouldn't blast wheel bolts on too tight anyway! Seriously over-tightened wheel bolts can be a big problem to remove.
