Detecting Problems with Your Volkswagen Jetta Lug Bolt
Your Volkswagen Jetta lug bolt is not just an ordinary fastener. It is a heavy-duty component that keeps your wheels securely attached to your vehicle. Even though it is made to withstand extreme vibrations, there will come a time when the bolt will finally bid you goodbye. When this happens, you know that your wheels are in a big trouble. But don't fret. All you need to do is to troubleshoot the causes of the problems to arrive at the right repair solution.
Rust may not affect the bolt head severely, but it can damage and ruin the threads completely. You can determine the extent of the corrosion by visually inspecting the bolt. You need to remove them one by one using a ratchet and a wrench. But if the bolt is very hard to take out, you might need to tap the bolt head gently with a hammer. Once the bolt is out, look closely to the threads and find signs of rust. When rust is prevalent to every thread, you need to buy and install a new set of lug bolts.
Lug bolts are usually torqued very tightly to make sure that the wheels are firmly attached to the vehicle. When the time comes when you have to replace them, expect that your lug bolts won't easily come off. Stuck bolts indicate that rust has already torn the threads down. The best way to take out stubborn, rusty bolts without breaking the bolt head is by soaking them with penetrating oil. WD-40 is the most common penetrating lubricant in the market. You can buy it at any local auto parts store.
Broken bolt head
The head of the lug bolt can break if extreme force is put on it. Without the head, you'll find it very difficult to remove the lug bolt. After a thorough inspection and you've confirmed that the head is completely ruined, you should be ready for the next step. You'll still be able to remove it, but it would take a more complicated process. First, you need to heat the bolt using a propane torch. Heat will allow the bolt to loosen up. Next, you need to hit the bolt slightly with a hammer. If those aren't enough, you might need to drill to the center of the bolt. Once it's cracked, you can extract it from the vehicle.
