The 1988 GMC Jimmy is the kind of SUV that can go anywhere, but after decades of use, it’s time to check on the engine mounts, suspension components, and brake system to make sure it’s still trail-ready. Whether you’ve got the fuel-injected 5.7L V8 or the 6.2L diesel, a fresh fuel pump and ignition system can keep it running like new. A common issue with these trucks? Worn-out steering components—if your Jimmy is feeling loose on the road, check the pitman arm, idler arm, and steering box for play. And if your weatherstripping is letting in water, a fresh set of door and window seals can keep your interior dry.
