* Hard to open/close? This could be due to misalignment, binding hinges, or worn weatherstripping.
* Doesn't latch properly? The latch mechanism, striker, or door alignment might be at fault.
* Gaps are uneven compared to the other door? This indicates alignment issues.
* Door sags? Worn hinges are likely the culprit.
Before you begin *any* adjustment, consult a repair manual specific to your 1997 Chevrolet Tahoe. This will provide diagrams and detailed instructions. Improper adjustments can worsen the problem.
Here's a general outline of potential adjustments, but remember, this is not a substitute for a repair manual:
1. Inspect the hinges and weatherstripping:
* Hinges: Check for looseness, damage, or rust. Tighten any loose hinge bolts. If hinges are damaged or worn, they'll need replacement.
* Weatherstripping: Replace worn or damaged weatherstripping as this can affect door operation and closing.
2. Alignment Adjustments (usually require loosening and repositioning hinges):
* Vertical Alignment: This usually involves loosening the hinge bolts (top and bottom) slightly. Adjust the door up or down by carefully lifting or lowering it while keeping the door supported. Then tighten the bolts once the desired alignment is achieved. You may need to adjust both hinges on the door to achieve a level adjustment.
* Horizontal Alignment: Similar to vertical adjustment, loosen the hinge bolts, adjust the door left or right, then tighten the bolts securely.
* Latch Alignment: If the door doesn't latch properly, you might need to adjust the striker plate (the metal piece on the door frame the latch engages with). This often involves loosening the striker plate bolts, shifting it slightly, and then tightening the bolts to secure it.
3. Latch Mechanism:
* The latch mechanism itself could be faulty. This usually requires disassembly and inspection or replacement of components.
Important Considerations:
* Safety First: Use jack stands or other proper supports to keep the door supported during adjustments. Never work under a vehicle supported only by a jack.
* Tools: You'll need various wrenches and sockets, possibly a pry bar (used carefully), and a helper to hold the door in place during adjustments.
* Patience: Adjustments often require multiple small tweaks to achieve proper alignment.
If you're uncomfortable working on your vehicle, it's best to take it to a qualified mechanic. Improper adjustments can lead to further damage and safety hazards. A repair manual is an essential resource for this type of work.
