How do you lock the front so that it doesn't spin when you tighten the front wheel spacers?

 

Put the car in 4lo and keep it in gear (cars off obviously). Or have someone step on your brake while you tighten.

 

 

Or impact wrench!! Mine didn't move!

 

Good solid screw driver wedged in the rotor slots which then jams up against the caliper when you tighten it

 

this is what i did on both jeeps.. works great no damage!!

 

^^^^^^This....

 

NO! NO! NO! I would never use an impact to tighten lugs, it's a great way to over tighten and stretch the lugs (among other things).

^^This, although I just held it and didn't let it jam into the brakes (and it also helps to have someone step on the brakes.)

 

Thanks guys!

 

Place one end of 2x4 braced on the ground and the other end on a lug. The wood won't damage the threads and the ground will provide the resistance needed to torque to spec.
