Known issues on the 1987 V2500 Suburban. NHTSA has one owner complaint on record for this year, filed against the steering. With so little reported there is no pattern to draw, but a heavy four-wheel-drive Suburban puts real load through the steering box, the linkage and the front axle, and diagnosing looseness means checking each in sequence rather than replacing the obvious part. The manual lays out that sequence with published specifications, torque values and the related suspension and alignment procedures.
