Knuckle Replacement

I had a bad bearing on a Ford sport track course with no press. This knuckle assembly makes replacement much simpler and quicker pulled the old one off. This one slid perfectly in place fix the issue.

I originally thought the old tires were shot because there was no play in the wheel bearings. I was wrong and decided to go this route for my application for so many reasons. Trust me when I tell you I was dreading this, but it was a pretty straight forward repair and A LOT of videos out there on it as well. I would highly suggest having an impact for this one!! The parts seem very high quality so far and arrived on time via free shipping. This is my 1st experience with 1A Auto and I am impressed.

Perfect fit plus great price ??

Looked like the one online. Fit was perfect. Only thing was the Original axel nut was a 36 mm, and the one in the kit was a 35mm. I had to run out and buy a new socket. The 3 bolts on the back were installed with lock tight and rusted so it was a lot of work taking them off, but the new kit went in smoothly. I highly recommend this instead of pressing out the wheel bearing.
