  • Good Tool
Sturdy tool. Has a wide enough jaw to get around my Jaguar XKR lower ball joint. After struggling with separating the ball joint, I ordered this tool and had it off in 5 minutes.

  • Worked like a charm
Heavily built, no worry of jaws bending. Took a bit of pounding to get it positioned, but once in place it took only a couple turns of the screw to pop out the stuck bolt. Saved the day for my repair job.

  • Don't change tie rods without it!
Invaluable tool for tie rod ends on the BMW E46 Chassis.

  • The opening is big enough for BMW e36/e46/z3/z4 lower ball joints
Works great for BMW lower ball joints. The gearwrench and powerbuilt versions are too narrow to fit the lower ball joints this Astro is just big enough. CTA fits the best so far but double the cost. This Astro is strong and good price!

  • Small and perfect
A very handy tool to own. Not bad after all. Compact size dor easy removal of stuck ball joint rather than using a hammer to release them. Adjustable makes itceasy and I hope it will last long.

  • It works on short shaft ball joints.
It works on short shaft ball joints but add any more to it and it doesn't open wide enough to put it over needs another lower hole in the adjustable part then it would work all the time. Needs 3in to 3 1/2in not a 2in max opening size.

  • Best puller !
This is probably the best puller I’ve had. I have managed to destroy 2 ball joint separators previously, on a very tight job. Finally, I bought this one, Astro Pneumatic. What a great tool. So far, it held up on several ball joints, no sweat !!!

  • Buy it, you won’t regret it. Worth every penny.
Holey Moley! I just finished a complete suspension change on my 04 CRV. I originally rented ball joint removing pickle forks from my local autozone. I spent the next 5 hours hammering, spraying and heating the ball joints to try and remove them. Got many scraped fingers and banged up hand but no free ball joint. I stopped after that. When this arrived I literally took out all my ball joints in 15min. It was easy, safe and almost enjoyable. Love love love this tool. If your a car DIYer, you need this! Chris fix needs to get one of these instead of the BS pickle forks he suggested. Game changer. ... show more
