I've heard bad reviews of the polybush and the metal fatiguing due to the removal and refit of the bush.
My uppers were done on my driveway. My LR Indy is mobile do he did them while I went to work. No body mounts etc were moved.
I had similar issues with my old Hitachi compressor. A new AMK lives in its place.
I have the iid tool so I could update the software to the amk but also the pipes on my old unit were seized in place. Cutting them to fit the amk worked out best for me.
