It's been more than a decade since I bought my GMC truck. I haven't tried lifting it not even once. But now, seeing how muscular-looking my friends' trucks have been since they were lifted and fitted with big tires, I'm tempted to do it. What will I gain from such mod?
Performance-wise, lifting your truck's suspension will only become beneficial if you frequently drive your GMC truck off-road. Raising it and fitting in larger tires give the truck more ground clearance, which increases your capability in dealing with rocks and other impediments the rugged driving environment can throw at you. There are also cases when bigger tires provide better traction, and not to mention, greatly enhances the truck's appearance, making it look more powerful and masculine. If you're only after the aesthetics, you can use a body lift kit instead of suspension lift kit.
Are there important things that I should consider before giving my suspension-lift project a go?
Before you do the lifting, however, you have to find out first if such mod is legal in your area or not. Make sure that the modification you'll make won't violate any of the suspension regulations in your area. Also find out if your truck's suspension is capable of handling the additional weight of the larger tires. And, depending on the configuration of your GMC vehicle, you might also be required to do other mods just so your lifted truck can perform safely and more efficiently. Another thing you should consider is the changes that it will bring into the vehicle's handling. Driving a lifted truck may take some getting used to, so after lifting, don't go for hard-core offroading yet. Instead, take some time to learn the adjustments that you should make so you can have control over your newly lifted truck before you drive it of the beaten path.
My GMC V1500 has been with me since 1999. I managed to maintain it well, so it's still on the road today. Lately, I noticed that its fuel gauge is starting to function erratically, like indicating low fuel even if my tank is full. What could be causing it and how can it be solved?
It can be caused by a faulty sensor in the tank. It's possible that the sensor is reading the fuel level inaccurately, so that's what the gauge displays. This problem can be resolved by replacing the sensor with a new one. But since your ride has been with you for a while now and might already have high mileage, your technician might also recommend completer fuel pump module replacement.
The tailgate of my GMC V1500 won't open up; checked it already and I'm sure it isn't locked. What could be the problem?
Check your latch mechanism. It's possible that a washer in the said component has come loose, causing it to get stuck. To fix this, you may need to replace the washer with a new one or just put the old back in place if it is still in good working condition. This time, make sure the washer is securely installed in its place to prevent it from coming loose again. Depending on the structure of the latch mechanism, you may need to deal with clips rather than a washer. Sometimes, the vibration of the truck bed can cause the clips that hold the latch mechanism in place to pop off. You can fix this by putting the clips back in their places; secure them well with a high-quality tie wrap.
