Just fitted a pair of new tailgate struts to my 2002 Kangoo 1.4 - easiest job I've ever done. So pleased with the results.
I got my new struts off
, lots of suppliers, and paid £18.75 in total for the pair. They arrived next day, and fitted perfectly.
To get old ones off, I wedged tailgate open with a long plank, then prised off the old ones by tapping a flat-head screwdriver between the strut and the spring clip at each end. Clips come out easy, strut just unhooks from ball joint.
To fit new ones, just line up each end, gently tap with hammer, and it pops on. I had to push tailgate to max height to hook on the other end, but it was no trouble. A simple job easily within the capabilities of even the most timid owner.
Only one of my old struts had failed, but working out which one, when they are on the car, is impossible, and anyway, if one has failed the other will probably follow in a few weeks. For the price, swap both.
