Used this one time so far, I chose to remove the knuckle from the car to make it easier to remove the snap ring. I was able to remove and press in bearing with hand tools, I have impact gun, but chose not to use it. Lubed the forcing screw and washers and it was much easier than anticipated. Very glad I bought this kit over a cheaper one. 10/10 recommend

works as advertised. very sturdy. Just make sure you go slow and keep everything perfectly aligned if using impact wrench. Its easy to get off alignment --- and you don't want that when pressing new bearings.

I used this on my lower control arm. Sadly I failed. But it is not the tool's fault. I don't have all the adapters. So I used one that looked okay, but it did not work in the end. I had to buy a new LCA to get the job done. Next time, I will make sure that I have all the adapters before I press the bushings in.
