I shall need to give my Xantia rack some much needed attention soon as the Teflon has worn off the bushes on the ends giving a distinct grinding sound when I turn corners especially in the winter when it is cold,
Martin @ Pleiades says its OK for now and it wont Break, I pierced the boots on the ends with a syringe needle and inserted the nozzle from a can of spray lithium grease and filled my boots...
piercings up with superglue.
