call precision, they do all the work around were we live, and all parts are lifetime, you have that single pring which should be double, but they did these cheap when they put them in and even though houses are only 5-10 years old the door work was cheap, they will also put in the neopruine wheels and bearings and you are set for life will take them about 2.5 hours and you will need new cables total cost was 646 and it is lifetime and they are all over us, they only thing that could go wrong is the opener after you have them fix it, but these double wides are to heavy for single spring and trust me these guys have done 455 of the 900+ houses in whittney ranch everyone on the block has had theirs changed over due to that problem, let them do it and they can show you how many they did in our block, had mine done last year and you cannot even hear it open and they check it once a year, don't go back to single spring trust me door way to heavy and you can't do it yourself, 361-8445 you will be happy you called them.
