I have an extremely noisy garage door. It is a segmented door with torsion springs. I would like to replace the wheels that ride in the track as they look to be the original ones. that would make them close to 25 years old. Has anyone ever done this? Is it something I could do myself? Thanks in advance for any advice.

Hi I would like an opinion on an alternitive to a concrete floor. But first let me give you some background as to why. I built a polebarn garage 24x26 last year with the intention to install a concrete floor at a later date when the gravel had time to settle. The garage is intended for working on my cars and had planned on installing a lift. My problem, last year we had alot of rain through out the year and this year seems to be the same. My yard has a natural spring and needless to say I have a high water table. And though I don`t have any visable water problems in my yard my neighbors do. I think if I lay concrete now or later it would crack and would be an expensive mistake. The garage is being used for storage right now and has no water problems. It`s about 5" above grade and is filled with crush & run and also 1/2",3/4' Gravel. I need a floor that will safetly support the weight of cars on jackstands and since I wouldn`t be able to install a two post lift I would like to use a portable lift. The weight I would need supported in a concentrated area on the high side 5000lbs (Datsun 240z 2600lbs, 68 nova 3400lbs) My idea is to level the gravel and build a welded sqaure tube support grid. Put flat concrete block in the squares of the flooring grid and weld 3' x 10 flat 11ga steel sheets over top to finish the floor. This is of course is just an idea and if it doesn`t fit my need safely then it won`t be built. Thanks, Mark
