Known issues on the 1990 V1500 Suburban. The complaint record for this model year is thin: a single owner filing with NHTSA, concerning the steering. On a full-size four-wheel-drive wagon the steering system is a linkage of many wearing joints, and diagnosing play in it means working through the box, the pitman and idler arms, the tie rod ends and the front suspension geometry in order. The manual sets out that inspection, with published specifications, torque values and alignment procedures for the components involved.
