My slider door tends to noisily trundle shut as apposed to smoothly gliding shut !. Would new rollers make much diffence do you think or should i save myself the expense and give it a good greasing ?.
Dont grease your rollers or tracks you will make them worse They have bearings in them that need oiling and they need friction on the wheel against the track to make them roll on the bearings Clean any grease out of the track with somthing like kerosene then clean the rollers and bearings and oil up the bearings I bet it feels a lot better for it
It's well worth a mornings farting about to take off the door then all the roller fittings and take them to pieces as much as possible. Crud gets trapped behind the roller wheel on the middle hinge. It takes some prising off but this is the one that'll make the most difference. Once you get it all clean you will find a special hole to oil the u-hinge for instance so clear this out and use it occasionally. Get all the crud out of the middle track and as Para says a smear of grease - really the least you can is all - any more and the block will scoop it into a heap anyway. The nylon block - if you're hinge brass bushes are worn it can lead to the part on the track sitting rear up so the nylon block scrapes the top of the track - replace the bushes. Conversely if you've had to adjust the height of the door with the rear hinge, you may have ended up with the hinge sitting rear end down causing the top of the slot in the guide block to foul the track and take the weight of the door - file the groove in the block deeper so just the sides touch the steel track. Bottom rollers changed over the years but lates should have sealed bearings. Again, scrape away all the crud and lastly all the crap from the track. No grease in here as said above it stops the wheels working. Another common problem here is the fixings for this one have slipped with the weight of the door causing the bottom of the bracket itself to scrape it's way along the track. Loosen the fixxings, lift and push the bottom of the door in to change the angle as required and re-tighten. Top roller - Pull it off, clean, smear of grease, put it back. If your door is stiffer at some points check this one isn't jammed against the top of the track. If yes, remove plastic cover, adjust bracket downwards. When you're done a slight push or a small incline and the door will run on it's own.
