Question
how long does it usually take to replace an old door with a new one? i have a 4 door 2007 toyota rav4. i want to replace the drivers side back door. thank you

Answer
Cricket, Do you mean that you are going to do it yourself and need to know how long it will take you, or are you planning to take the car to a shop and are wanting to know what a reasonable amount of time for the repair? Also, I will need to know if a new OEM door shell is being used or if you're going to use a complete used door from a salvage yard. Thanks
