And if you are dropping the subframe anyway, the tool is more effort than properly applied fire.
    Takes no more then 5 mins with the tool to remove the bushings with or without the subframe removed...I don't like wasting time on shit if I dont need to...and if you're going to replace the rtab you still dont need to remove the subframe. ..its stupid and unnecessary to remove the diff for this job unless your changing out the bushing for it.

    Question: could you slice up a full pizza without a pizza roller? Yes. Would it be a lot easier with a pizza roller, of course. RSFB replacement can follow the same logic.

    If you are *just* replacing the subframe bushings, then it makes sense to use the tool and do it on the car.

    If you intend to do more (like the trailing arm bushings), it makes more sense to pull the subframe.

    $800 is not a bad quote for that kind of work, it does take all day.

    Sometimes this works. This is what I did. Didn't exactly come right out. Ended up getting a steel chisel and split it in half.
    You didn't use enough heat, then. :p MAPP at least. Forget propane.

    Rent this, it'll save you a major head ache and you don't need to pull the subframe to do it.

    Heat the subframe instead. Once you melt the rubber on the outside of the bushing's metal ring, it'll slide right out. And with FAR less nauseating black smoke.

    Ya need a blow torch
    And then a hack saw to cut out the metal ring
    Connect the blade through the center n cut
    Use a hammer n screw driver once fully cut
    Don't score the subframe with the saw
    Press in new bushings and re install

    I just removed my rear subframe & took it to a suspension shop. $50 later, they pressed out the old bushes and put in the new ones.

    Is that how you got your front subframe out? You don't get to work on my car.
