get a BIG breaker bar Posted by Snowmobile [Email] (#686) [Profile/Gallery] (more from Snowmobile) on Wed, 20 Jun 2012 03:22:13 In Reply to: Lug nuts and the Saab wrench, GFW3pedals [Profile/Gallery] , Tue, 19 Jun 2012 07:59:40 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I run into this sometimes when other people tighten my wheel bolts (on this car and on my c900's). I now have a 4' solid inch thick breaker bar with 3/4" drive. I've bent too many 24" breaker bars removing wheel bolts from guys who don't know their own strength. The other thing though is to never get anti-seize on the threads! We had one once where a junior mechanic intentionally did that, then overtightened. This was before I had my own good breaker bar, but it took the guys at a tire shop an hour of very intense effort to get the wheels off! In that situation, the car rocks back and forth a lot + it can help to have someone step on the brake while another cracks the bolts.
The torque spec is a little lower for the 9-5 than the c900 (c900 uses thicker bolts), but I basically torque both to between 90 and 100 lb-ft using a torque wrench whenever I change wheels. I do use an electric impact wrench to get the bolts on fast + then hand torque each one. The torque wrench I use is just a cheapy $20 mechanical one and it works just fine. I can always crack bolts I've tightened (with a normal wheel tool, not the big breaker bar) and they never come loose.
It is amazing that you bent the Saab wrench. It is so short that it is useless. I have put pipe over it and never been able to bend it. It seems pretty robust, just really short. Besides a "+" style tire iron is way more efficient on the side of the road, at least for me, since it will spin...
