I want to replace my rear struts from a 1998 Grand Prix from a 2003 Buick lasabre
Hello - according to the interchange manuals, yes, the rear struts are interchangeable for these 2 GM vehicles. I would certainly compare them visually before disassembling your Grand Prix, just to be sure. If you need assistance, I recommend strut replacement by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
