It installs as a fully assembled, direct-fit replacement for the 2003-2006 Acura MDX — see the Buyer's Guide tab for engine-level fitment. Fit checked and ride tested, this Quick-Strut arrives ready to bolt in with no spring compressor needed.

What vehicle does the Monroe 172230 fit?
It's a front-left Quick-Strut assembly for the 2003-2006 Acura MDX. Check the Buyer's Guide tab to confirm engine-level fitment for your specific vehicle.
Do I need a spring compressor to install it?

It's an all-in-one unit that includes the preassembled upper strut mount, application-specific coil spring and strut needed for the front-left strut replacement.
Should I replace both front struts at the same time?
This listing is for one front-left assembly. Replacing both front struts together as a matched pair is recommended for even, balanced ride and handling, though not strictly required.
What are signs this strut assembly may need replacing?
Common signs include excessive body sway, bouncing, uneven ride height, or increased vibration and road harshness. Have the suspension diagnosed to confirm the cause before replacing.
