On checking the pre-load was up to max ready for our Spanish Trip on Saturday the adjusting wheel on my glee was too stiff to turn by hand as I tend not to adjust it much. Thinking it may have seized I applied lubricant to the top of the shock and thought I'd take the adjusting wheel off to check if the mechanism was gummed up.
What I didn't know was the fact that there are 2 spring loaded bearings underneath the wheel which did what spring loaded things tend to do - they shot all over the Garage floor! Much grovelling about turned up 1 of the bearings and luckily I had another the right size. Big glob of grease to hold them in place while I re-installed the Adjuster did the trick.
Note to self - get a manual!
