Ive got almost the same problem with my left stilt, only found out the problem this morning since I discovered my left stilt just didnt sound right at all, always made a "clunk" sound when I stepped on the ground with it, the right one felt solid and made no noise at all. Ive had this problem since I got my PJs last Friday and put them on.
The poor lass on the other end of the phone when I phoned up Pro-Jump couldnt understand what I ment by "The bracket that holds the top of the spring to the L frame is wobbly".
This is the only part of my Stilt that is "loose" and "wobbly" and because of it, everytime I take a step with it, it does feel as if the foot plate itself is going to fly off
On a not so serious issue, the right angle part of the L frame, there is a large, long, cylindrical washer on the inside and it rattles, I dont see it causing much of a problem but it doesnt half make a fuss. Not sure if the issus are related...
Ive kindly been asked to return the stilts with a return order form to Pro-Jump HQ (doesnt that sound awesome?!
) though it'll be Tuesday as I dont want to miss out on Capital Bocking.
