Now that the stock stabilizer bar is somewhat free to move from side to
side, shift the bar to one side in order to remove the upper end link nut
using a 21mm wrench and 7mm Allen Wrench. Once you remove the

other end link. This method gives you more room to easily remove the nut
for each end link. Save end links and hardware for reinstallation.
