My upper and lower control arms just arrived. I have all the tools needed, Just need to make sure I have enough time to get it done and still be able to drive to work. Which ones take the most time, upper or lower? Also,can the car be driven a short distance before an alignment is done once the LCA's are replaced? I only have a 8 hour window to do the job this weekend. I have talked to a couple other people and they said if you mark the dials on the LCA bolts, and alignment may not be needed. Thanks for any input!
