Fitment Chart:

✔ Fits these vehicles — AWD models only

⚠ AWD models only (the “x” models). Does not fit RWD M37, M56, or Q70 models.

The unit includes the electronic solenoid.

On the M37x — steering feel off, but no leaks and no play in the rack? It may be just the EVO sensor — we sell it separately: NEW $155.99 or USED $145.39.

Signs yours is failing

• Steering feels loose, stiff, or has play
• Power steering fluid leaking at the rack
• Clunking over bumps or when turning
• Uneven front tire wear

How the core return works

There's no core charge when you order — nothing is added at checkout. After your new part is installed, ship your old part back to us within 30 days — return shipping is on you:

OK Speedline Auto — Core Returns
4600 W Chicago Ave, Chicago, IL 60651

Your core must be the same year, make, and model as the part you purchased. Cores that are bent, broken, or missing parts will not be accepted — no exceptions.

Once your acceptable core arrives, your lifetime warranty is activated. If we don't receive your core, the part carries a 30-day warranty instead of the lifetime warranty — and you're still never billed a core charge.
