I am going to repalce the axle bushings soon and i was wondering if there is a load on the upper control arms and if they are heard to line back up with the bolts?
They can be a pain -- you may have to pound on the bolts and move the axle around to get them back in. When you take them out, they can be under some load -- but if the axle is supported you shouldn't have any problems. Be sure to do a final tighten with the car supported by the axle, like when it is on the ground.
