    Ball Joint Separator Tool

    In need of a ball joint tool for front control arms, the ones I currently have are too short. Anyone here in Socal have one for rent?

    Harbor freight one works well and then the trusty pickle fork and a mini sledge hammer.

    I do have this one from HF and is not tall enough. Only works well on tie rod/thrust arms. The BMW specific tool is substantially taller

    For the inner ball joint on the control arm I use a pickle fork, you can rent it from Autozone.

    None of the rentals at any stores, including autozone, advanced auto, and harbor freight, will work. Ask me how I know. And, IMO, the sledgehammer ideas are bad due to the complexity of the E39's suspension system.

    I ordered an "Orion Motor Tech Ball Joint Separator, Universal Ball Joint Puller with Lower Control Arm Prying Tool Compatible with Ford Lincoln Mercury, 2-3/8 in. Lower Ball Joint Remo" from amazon as an alternative to dremeling down the stud. (Came so close, but I was wondering about the other side, and that the part is probably forged steel.) The cost was under $30 including the taxes and overnight shipping. For cases where you cannot wait, hit up your metal grinder/slicer/dremel.

    Any ideas as to why stores don't carry units that fit? Is this some dealer incentive thing?

    The HF one works on everything I've used it on including the e36 which I maintained for well over 12 years. There's two holes for pivot points, are you using the correct one?
