I developed a "thunking" noise on the rear passenger side and narrowed it to the cup or upper spring pad. I removed the strut assembly and compressed the spring. I attempted to remove the upper nut holding the shock with a wrench and a vice-lock, as is usually done. The gripping area above the nut broke off, however.\n\nI need to remove the shock. At this point, I'm fine with destroying the current shock and replacing the rear pair. They look like original equipment which means 50K and 18 years!! So basically, I'm looking for advice on removing these corroded in old shocks. My 2 foot bolt cutters are not large enough. Hack saw? Do I need a cutting torch?\n\nThe actual vehicle is an '02 XG350, but the rear strut assembly is identical to the Sonata, so I decided to ask here for a larger community.
