Here’s the short version: if you’re replacing a ball joint, an engine mount, or a water pump on a car you intend to keep for more than a year, buy Lemforder (or the equivalent OEM brand). Don’t cheap out.
I'm a fleet mechanic at a mid-size logistics company. I've processed over 500 emergency parts orders in the past four years, including same-day turnarounds for delivery trucks that had to be on the road by 5 AM. When I'm triaging a rush repair, I don't have time to second-guess parts quality. I need something that fits, lasts, and won't come back. And after testing six different aftermarket brands for ball joints alone, I've settled on Lemforder for the critical stuff.
One of my biggest regrets? Not switching sooner. I still kick myself for the three months in 2023 when I tried a budget brand to save $40 per ball joint. The first one failed after 14,000 miles (on a 2012 Chrysler 200, ironically – the same model you're probably searching for alternator information on). That failure cost us a tow, a replacement, and a missed delivery penalty. Total cost: roughly $850 vs. saving $40. (Note to self: stop being penny-wise, pound-foolish.)
Why Lemforder for Ball Joints?
Lemforder is the original equipment supplier for German manufacturers like BMW, Mercedes, and Volkswagen. Their ball joints are cold-forged and come with a Teflon-coated bearing surface. I've pulled 10-year-old Lemforder ball joints off trucks that still had zero play. The aftermarket replacements I've tried – even the “premium” ones – rarely make it past 60,000 miles on heavy vehicles.
I don't have hard data on industry-wide failure rates, but based on our internal records from 200+ ball joint replacements, the Lemforder units had a 0.4% return rate over two years. The runner-up economy brand: 6.2%. That's a 15× difference in failures. For a part that can kill you if it lets go, I'll take those odds.
Engine Mounts: The Quiet Problem
Lemforder engine mounts are another no-brainer. Most people don't notice a worn mount until the engine starts banging against the subframe on hard acceleration. But that vibration kills other components – exhaust hangers, coolant hoses, even the flywheel turner tool you use for clutch jobs can get damaged if the engine shifts during service.
Take this with a grain of salt, but I estimate that ignoring a bad engine mount costs roughly $300 in accelerated wear on other parts over 20,000 miles. A Lemforder mount costs about $90 on average – comparable to many aftermarket brands. But the aftermarket ones often use softer rubber that degrades in 3 years. The Lemforder one uses natural rubber bonded to metal. I've seen them last 8 years on a 2012 Chrysler 200 (yes, that same car).
What About Water Pumps? (And What Even Is a Water Pump?)
Since someone searching “what is a water pump in a car” might land here: a water pump circulates coolant through the engine to keep it from overheating. It's a simple impeller-driven pump, usually powered by the serpentine belt. But “simple” doesn't mean “cheap to fix when it fails.” A failed water pump can dump coolant, overheat the engine, and warp the cylinder head – a $2,500+ repair on most modern cars.
Lemforder doesn't make water pumps directly (they're mostly suspension and steering). But their parent company, ZF, does supply water pumps for many European OEMs. For the 2012 Chrysler 200, you'll likely need a pump from Gates, ACDelco, or the dealer. But the philosophy is the same: buy a brand that supplies the factory. For Chrysler, that's usually Gates or the Mopar OE.
I wish I had tracked water pump failures more carefully. What I can say anecdotally is that aftermarket pumps under $60 tend to leak in 2–3 years. The OEM-level pumps ($80–$120) nearly always outlast the timing belt interval. And since you're paying labor anyway, the incremental cost is trivial.
The Flywheel Turner Tool: Don't Forget the Support
While we're on the subject: if you're doing a clutch job on a 2012 Chrysler 200 (or most front-wheel-drive cars), you'll need a flywheel turner tool to lock the flywheel while torquing the pressure plate bolts. Lemforder doesn't sell tools, but the concept of “buying the right tool for the job” fits the prevention mindset. I've seen mechanics try to get by with a screwdriver; they end up stripping teeth or damaging the flexplate. The proper tool costs $30 and saves hours of rework. (Obviously.)
When Can You Cheat?
I'm not saying you need Lemforder for every suspension bolt. Here are the boundaries:
- Sway bar links and tie rod ends: aftermarket is usually fine. They wear out faster anyway and are easy to replace.
- Control arms for low-mileage cars: if you only drive 5,000 miles a year, an economy arm with a 2-year warranty might outlive the car.
- Water pumps on throwaway cars: if the car is worth less than $3,000, a cheap pump might be rational. But be ready to scrap the car if it fails.
But for ball joints, engine mounts, and anything safety-critical? Spend the extra $20–$50. Your future self (and your mechanic) will thank you.
