Original Bush vs Polyurethane – What’s the Real Difference?
If you’ve been hearing a persistent “erk erk” sound from your car’s undercarriage while turning, braking slowly, or driving over bumps —
and your vehicle is over 10 years old or has more than 100,000 km on the road,
the issue is likely caused by worn or cracked lower arm bushings.
Many believe that polyurethane (aftermarket) bushings are better — stiffer and more durable.
But based on real-world experience:
❌ Over time, polyurethane bushings often:
– Develop small gaps between the bushing and metal
– Create abnormal friction and wear
– Produce even more noise than before
– Result in a rougher and less comfortable ride
Genuine Toyota | Lexus bushings are engineered for:
✔ Ride comfort
✔ Suspension quietness
✔ Long-term flexibility and stability
✔ Compatibility with factory suspension geometry
At MD AUTO, we’ve seen many customers who switched to polyurethane bushings eventually return to reinstall original bushings — just to get back that refined Toyota / Lexus driving feel.
If a quiet, smooth, and well-balanced drive matters to you — Stick with original parts. It's not just better — it's smarter.
