Rear axle bushes are easy enough. I'd advise fitting poly bushes just for ease really as you won't need a puller to fit them. Done quite a few on the floor (mobile mechanic) I drop the back beam off. Disconnect the brake pipes at the fixed mounting (clamp the brake lines), disconnect the handbrake cables, remove the rear
lower shock bolts then off it comes. I cut through the old bushes with a hacksaw fed through the bush and some WD40 to lube the blade through the rubber. Then the poly bushes will tap in with some washing up liquid. Worst part of the job is getting the beam back into the mounts when working alone, easy with a helper and then just bleeding the brakes up properly!
