The strut top nut is accessed from inside the engine compartment. Hurried mechanics often use an air-powered impact wrench, but it is better to use a deep-offset box-end wrench with a long hex key holding the strut shaft to remove the nut. I couldn't find a 22mm deep-offset box-end wrench in the Craftsman catalog, so I went to Harbor Freight and bought a whole made-in-India set for $9.99. On the Jetta, the wrench didn't fit inside the strut top mount at first, so I took the 22mm wrench over to the big, bad, belt sander and made it fit. I was amazed when the wrench didn't break. I began to feel a little cocky.
