If your Mercedes is feeling loose in the front end or you're hearing clunks over bumps, this control arm might be the fix. It's a brand new front right upper control arm, complete with a pre-installed ball joint. Made by Detroit Axle, and it comes with a solid 10-year warranty. Part number X90422, which replaces OEM number K90422. Fits a bunch of Mercedes-Benz models from around 2000-2001: C220, C230, C280, C36 AMG, C43 AMG, CLK320, CLK430, CLK55 AMG, E320, E420, E430, E55 AMG, SLK230, SLK32 AMG, SLK320... you get the idea. Covers both Kompressor and non-Kompressor engines from 2.2L up to 5.5L. The arm is polished and rust-protected, so it looks good and lasts. Includes all necessary bushings and the ball joint – ready to bolt on. Direct replacement for the original part. If your old arm has worn bushings, a torn ball joint boot, or just too much play, swapping this in will tighten up your steering and improve handling. Great for DIY mechanics or shops. Installation is straightforward with basic tools – just support the suspension, unbolt the old arm, and install the new one. Alignments are recommended afterward. Keep your Benz driving like it should. A quality aftermarket part that won't break the bank. Get that precise German feel back.
