Lined up perfectly with the original. Install took about an hour with the right press. Solid feel back in the steering, no more clunk over bumps.

Ordered on a Monday, had it by Wednesday in Calgary. Greasable fitting is a nice touch. Quality looks on par with OEM.

Works great so far. Just confirm fitment for your exact trim before ordering — the fitment list on the page was accurate for mine.
