If you've ever typed any of these questions into a search bar, I bet you know the feeling. There's a stack of parts to order, a customer waiting, and you just need a straight answer. I'm the office manager at a 14-person independent repair shop. I don't turn wrenches, but I buy the parts, file the returns, and keep track of what actually fixes the car. I report to the service manager and the owner, so I hear about it from both sides. Over the past 5 years, I've processed a few dozen parts orders every month—roughly $120,000 a year in parts across about six vendors. This is what I tell people when they ask about Moog parts and a few other random maintenance questions.
I've split this into five questions I actually get, starting with the two Moog ones.
- Are Moog ball joints good?
- Is the Moog K8787 stabilizer bar bushing kit worth it?
- Can a muffler get clogged?
- 2000 Silverado oil filter: what do I need to buy?
- Should I switch to an LED motorcycle headlight?
Are Moog ball joints good?
Short answer: yes, for most daily drivers and stock-height trucks. Long answer: the right Moog part for a specific vehicle is good; the wrong part for that same vehicle is just an expensive box of disappointment.
It took me about 150 orders to understand that 'good' isn't one thing. I used to assume 'same specifications' meant the same result from every brand. Didn't verify. Turned out each manufacturer has its own load limits and small design choices that matter mostly at the edges. Moog is one of the brands that makes those choices visible. When I check the product page (I looked again in March 2025), they call out things like a hardened stud, a heavy-duty shell, and a grease-able design. Those aren't magic. But they do mean a Moog ball joint can be maintained instead of just swapped out, assuming the tech actually greases it. I try to put that on the repair order: 'grease all grease-able suspension points.'
The March 2023 failure changed how I think about this. A customer's truck came in with the classic ball joint clunk. We installed a no-name aftermarket joint, and it was back three weeks later with a torn boot and a dry socket. I had to explain why we paid labor twice. That won't happen again. If the tech asks for Moog, I order Moog. If they don't ask, I show them the difference with the two parts in my hands.
For the trucks we work on, Moog's ball joints are my default. I won't say they're indestructible, because no joint is. But I've had far fewer comebacks on Moog suspension parts than on the budget stuff I bought during my first year. That's a real-world sample of roughly 100 ball joints, not a marketing claim. And before you ask, yes, I know ball joints eventually wear out. That's why I don't order them without checking the mileage and the condition of the tire. If the front tire is already scalloped, a fresh ball joint won't fix the real problem. We tell the customer the truth: this component is nearly done, and ignoring it now means a bigger repair later. That's the prevention-over-cure part of my job, and it's why I like a grease-able part in the first place.
Is the Moog K8787 stabilizer bar bushing kit worth it?
The Moog K8787 stabilizer bar bushing kit is one of those small parts that can make a front end feel quiet again. If you've ever tried to chase a clunk over speed bumps, you know how easy it is to throw parts at it. The bar bushing usually isn't the first thing people think about.
What I like about the kit: it comes with the bushings and, if I remember correctly, the little metal retainers or brackets you need for the job. Don't quote me on exact contents; I learned the hard way that box contents change by application. Always open the box and compare the old part with the new one before removing anything. That's my rule now.
Do it in pairs and don't skip the check. Five minutes of verifying the bar bushings, end links, and sway bar hardware before you order can save five days of waiting for return authorization. I still kick myself for buying a budget bushing kit once and ignoring the fact that the bar was bent slightly. If I'd checked the bar first, I'd have seen the real problem. The kit didn't fix the clunk, and the customer came back with the same noise. That's the kind of mistake that teaches you to look at the whole system, not just the part in the box.
Can a muffler get clogged?
Yes. I've seen it three times in five years. Usually an internal baffle collapses, or rather, in one case it was chunks of catalytic converter that broke apart and plugged the exhaust. The car idled fine but couldn't get past 55 mph on the highway. There was also a faint rattle, like gravel stuck inside a can.
A clogged muffler is rare, but it's real. A quick backpressure test can confirm it in about ten minutes. That's cheap insurance. I remember a car that got a fuel pump and a coil pack before someone finally checked backpressure. The muffler was almost blocked solid. That mistake stuck with me, not because the parts were bad, but because nobody took the time to test before guessing. If you want to check before all that, feel the exhaust flow at the tailpipe with the engine idling. If it feels weak and the engine has no code for a sensor issue, a backpressure test is your next step.
2000 Silverado oil filter: what do I need to buy?
The easiest way to answer '2000 Silverado oil filter' is to ask which engine. For the 4.8L, 5.3L, and 6.0L V8s, the ACDelco PF61 is the filter I order most. For the 4.3L V6, the part number can be different. Either way, verify with the VIN. I've seen online lookup tools disagree with each other, so I don't want to send you to the wrong one.
In our shop, we use ACDelco or an equivalent that has a good anti-drainback valve. That valve keeps oil in the filter when the truck sits overnight, so the next cold start doesn't grind. I also write the date on the filter with a paint pen. That little 30-second habit has saved me more than once when a customer asked me if the oil had been changed recently.
It took me about 150 orders to understand that 'will fit' lists are starting points, not gospel. I ordered the right-sounding filter once, and the thread pitch was wrong. I had to eat the return shipping (I really should stop trusting those 'universal' charts). A 2000 Silverado is old enough that little variations matter, so verify before you buy.
Should I switch to an LED motorcycle headlight?
I'll step off the Moog side of the desk for a second, because this one comes up a lot. Yes, an LED motorcycle headlight is usually a big upgrade, if it's the right LED. The catch: the housing has to be designed for it, or the light scatters. I learned this after I recommended a budget plug-and-play bulb to a friend. He came back a week later saying the low beam was 'like a flashlight pointed every direction.' Oncoming cars would've agreed.
Look for a motorcycle-specific LED with a clean cutoff, aim the beam after installing it, and check your local rules. That last part isn't me being careful for no reason. A bad beam pattern is not just a nuisance; it can fail an inspection or make a rider hard to see. The upgrade is worth it when you do it properly. And if the bulb needs an adapter or a different harness, don't force it. That kind of shortcut is how you end up with a bike that has one high beam and one low beam.
