Rear suspension bushings

[Garry k]

Hi all finally started working on my 75 connoisseur as I seem to have a bit of time on my hands due to lock down and garage cleared out to get the car in.so I've started to strip the rear suspension apart to referb got both trailing arms off and looking at the bushes they all look prity solid but before I removed it from the body I could swin the arm 2 to 3 inc side to side is that movement with the weight of arm hanging on normal or has the rubber just gone soft and worn-out . As the bushes have probably been in from new 2001. Any thoughts
Cheers Gary
