Mercury Regatta mobility scooter?

A mate is selling his wife's (she passed away recently) Mercury Regatta mobility scooter and I'm considering it for my Mum (90). She did ride Dads lightweight / take-down trike but when coming to a halt on the down-amp at a pedestrian crossing, rather than just letting go of the throttle bar her ancient cycle riding muscle memory kicked in and she pulled what she for that second thought was the front brake. ;-( Luckily I was ready for such and event and was just able to hold her back from going straight out in front of a 4X4 (that very considerately didn't slow down but just sounded the horn). ;-( So, rather than a finger operated, brake-like f/r throttle bar, this Regatta has a thumb(s) operated 'Wigwag paddle' and apparently my sister hired her something like that at a garden centre and she got on with it well (no mishaps). Anyway, mate has let us have it on approval to make sure 1) we can get it into Mums back garden easily and 2) to see if she's happy with it. I have previously done a discharge test on the 50Ah batteries and they were both around 40Ah so still useable. So, we got it to ours tonight with the thought of taking it to Mums when we get a chance (one of us can ride it there) and when giving it a quick look over (I was going to treat the tyres (tunes) with Punctureseal and pump the tyres up etc) I felt the front suspension (a coil-over-shock on a trailing arm, like a sand rail ) and it felt non existent. I first put the grease gun on the main pivot nipples and it took a few pumps but I saw no grease anywhere. Not wanting to fill the arm with grease, I thought I'd better give it a closer look. I removed the nsf axle bolt and had to tap the wheel off with a rubber mallet. Then, to get the swinging arm off I had to disconnect the track rod end, the spring damper and the king-pin (large socket head bolt with Nylock nut) and stub axle assembly. I then released the trailing arm (central bolt and large washer) and pulled the arm off and it was very dry and...
