I'm a DIY mechanic, someone who buys all the tools they need to get the job done. While it's not the cheapest tool, I figured I'd get more than one use of it's with a few bit cars I have, as well as friends' vehicles. You have to do some work if you want it to pay off, but it works. A few tidbits about this device: * The instruction manual is very complete. You'll need a bit of mechanical intuition to match the drawings to the car itself as they use generic images for different cars, but any mechanic can figure it out halfway. * The application guide covers the period from approx. 1996 onwards. If you have older vehicles, please note that the guide does not cover them; you're alone. * It is highly recommended to lubricate the threads of all jacking screws to prolong the life of the unit. I just used the all-purpose lube I had and it helped keep the ride smooth. Pluses, but that's a pretty big key for a home master. Be sure to order one of these! I used it to replace wheel bearings on a Kia Sephia and it worked like a charm. and he easily removed the old bearing and pushed in the new one. Take your time, read the manual and wear safety goggles when working with this type of equipment as there is literally a ton of force going on the parts inside. I don't want something to fall apart and hit you!
