by chew up and pop, are you talking about the stud and frame area, or at the washer? I did take care to get the shoulder part of the bushing into the frame hole, and havent heard any noises indicating the stud hitting the frame. the washer is quite smooth, so IDK what would chew the bushing up.
Unfortunately to do it right, I really need to have it jacked up to ensure everything is centered, correct? I am afraid If I try to flip the washer here in the parking lot, the rubber will pop out and let the shaft beat around and waller out the frame hole. justified concern, or worrying about the impossible? I can do it in the parking lot right now if you think the rubber will stay put.
