It does appear hard to find in exploded assembly drawings, so I would call a dealership's parts department and describe the part as you have done here.

I've never had those done, since I change my own oil and oil and air filters. It's always good to look at your maintenance schedule to see what would be checked and/or replaced. If you've been keeping up with oil and oil and air filter changes, most likely, you are good to go without visiting the dealership to check various things.

Ha! My hands often look like that after replacing/installing auto-related things. I'm glad you were successful. I may be doing the same thing, some day.

Check out Magnaflow mufflers. I believe they have a variety of types, depending upon your sound preference. Independent muffler shops can sample various mufflers before you commit to any one. That's what I did for my Miata.

I believe that Carfax shows only service done at a dealership. I owned since new a 2014 Mazda 3. All oil/oil filter, and air filter changes were done in my garage with synthetic oil. I'm fairly certain that the Carfax reports showed none of those completed maintenance tasks. You may want to have a mechanic pull the pan to check for metal particles in the fluid.

I'm very surprised that Toyota/Lexus would risk its reputation by doing that. There are some high-quality dashcams out there.

Hello, Danh. Have you called the dealership parts department? They may have a touchup kit.

As a Consumer Reports subscriber for more than 40 years, I can tell you this: RX vehicles, including the 25% more efficient hybrids have been very reliable. However, if you are buying any vehicle that is more than 10 years old, its maintenance by previous owners is extremely important. Preferably, the current owner can tell and/or show you what was done over the years. But before you even discuss this, I recommend that you find the manufacturer's maintenance schedule, which will list mileage and dates of services. I would walk away from any vehicle for which the owner does not have this information.

I am fairly certain that that is not normal. My experience with runflat tires during the early 2000s is that due to their greater sidewall stiffness, the ride was harsher than that of non-runflat tires. I don't remember the noise level being that much different.

Does your dealership have its own body shop? I've taken ours to a Toyota Collision Center, a couple of times and they've always done an excellent job. Also, I don't think that you can demand that your vehicle be totaled by your insurance agency. My guess is that once the vehicle is put back together correctly, then thoroughly tested, there should not be "ghost" issues that randomly appear, later on. Of course, your ending up with a repaired and painted vehicle that is worth less is a common concern of accident victims. I'm not sure if there is a way around it.

You could try grinding a slot (with a Dremel cutoff disc) in each stud and with a large screwdriver, try to thread each one out. A strong, 2-part epoxy may provide a strong bond on steel dowel pins, but what happens if you need to disassemble the mirror?
