Look at these critical details before you swap parts out: - Match the exact hook spacing to prevent frame stress during recline motion - Install coil springs rated for heavy daily cycles to avoid premature snapping - Apply silicone grease to contact points so sliding tracks stay smooth forever - Check anchor brackets before mounting since loose screws cause weird noise issues
