So you were dutifully greasing your aftermarket Upper Control Arms (UCAs) that you dropped your hard-earned on and your kid starts screwing around with the cap. Sure enough, nek minute it's nowhere to be found and you find yourself Googling whether it's still illegal to punt under 5s.
Turns out it is, so rather than putting them out with the next council clean-up you take a deep breath and start looking for replacement caps, and Shamwow, here you are.
Nobody wants their UCAs looking like Friar Tuck, so keep the grit out of your grease nipple (look, there's no way to say that without sounding like it does, so let's all just collectively move on hey?) and grab yourself one or two of these and never worry about having to explain to your partner why your child is for sale on Gumtree, before slyly nominating yourself for Parent of the Year.
