MVS member 850LPT shows us exactly how to DIY a door check:
Shortly after I got my V70 last summer the driver side front door check failed. It had been repaired before, but the work didn’t last. It took me a little while, but last weekend all stars were aligned just right, and I went to work.
Thanks to this site, I had great infos on how to take the door panel off, and also on how to take the door itself off on just the pins (this was super easy!)
