I recently notice the steering wheel in my Toyota Van shaking whenever my driving speed goes above 50 KPH. However, the shaking would stop the moment I reduce my speed. What could be causing this problem?
There are several things that might be behind the problem. One of the most possible culprits is a tire that is out of balance in your ride. If shaking happens above 50 KPH but stops when you drive even faster, then check your tires to catch the problem. Another possible reason is a damaged or sticking brake caliper. If this is the problem, steering vibration will typically get worse as the car speed increases. Check the said components, together with your suspension system and steering assembly. Damaged bearings, broken suspension arms, wearing axles—all of these could lead to the symptom that you mentioned. You can also check the balance bar in your vehicle for possible damage. If the bar is broken, then the chassis will flex and cause the steering wheel to shake. Replace a damaged bar right away.
I'm looking at cleaning the throttle body installed in my vehicle, and I wonder if I can reuse the gasket and re-install it when I assemble the throttle body back. What's your advice on this?
We would suggest that you carefully inspect the gasket to see if it is still up to par. Any sign of tear, wearing, or even the slightest damage should automatically make you reconsider the reuse of the said material. Installing a damaged gasket would most likely cause problems in your drive, especially with regards to idling due to the presence of vacuum in the throttle. The best suggestion that we can give you is to replace the throttle body gasket regardless of the presence or absence of obvious signs of damage. This gasket comes cheap, and it's a practical thing to do to replace it together with the disassembly of the throttle body compared to doing the task all over again just to replace a damaged gasket. It's easier and cheaper in the long run.
How important are auxiliary lights? One of the front auxiliary lights in my Toyota Van vehicle is no longer working, but I don't have a budget for a replacement yet. Can I skip it for a while? Or is it absolutely necessary to replace this lighting component?
Auxiliary lights may not be central to your lighting system, but they provide crucial illumination when you drive in harsh weather conditions. For instance, foggy weather is something the headlight can't handle; you will need a fog light set for this in order to prevent accidents caused by improperly directed light beams. Driving in the dark will also call for additional lighting to ensure that you will see the road ahead clearly. Just remember that different auxiliary lights are created for different purposes; you cannot substitute another kind of light when the auxiliary light gets damaged. The only way to deal with this is to get the right replacement light for your van.
