Got a wobbly front end on your 2001-2006 Nissan Sentra? This lower control arm with built-in ball joint will fix those steering and alignment issues. It's the front left (driver's side) assembly, made by Detroit Axle, part number K620359. The whole thing comes complete - control arm, ball joint, and bushings all in one piece, so you don't have to buy separate components. It's brand new in the box with a polished, rust-protected finish that'll last. And get this - it comes with a crazy 10-year warranty! That's how confident they are in the quality. Installation isn't too bad if you're handy with cars - you'll need some basic tools and probably an alignment afterward. Fits Sentra models from 2001 through 2006, including XE, SE, Base, GXE, Sport, CA, S, LE, and Edicion Especial trims with the 1.8L engine. If your car is making clunking noises over bumps, or if your tires are wearing unevenly, this control arm could be the problem. Save money on shop labor and do it yourself - just make sure to torque everything properly and get that alignment done when you're finished!
