Learned that the hard way recently. Even on the car if you dont have everything together, it may be too much movement. QUOTE]
It also depends on which direction you pull them can help reduce/eliminate the car from moving when taking the upper ball joints loose while mounted on the car. I usually find it easier to pull parallel with the centerline of the car. :cheers:
Also use a good "cheater pipe". Go to the hardware store with the exact wrench you will use with the socket and buy a 2, 3, & 4 foot pipe that will fit over the handle of the wrench for extra torque. :D
It's good to keep a couple of good cheater pipes in the shop. If you can't break it loose, you can break it off with a good cheater pipe and go from there.... :violent1:
