I replaced the center roller on the passenger side sliding door today.
Symptoms were 'jerkiness' when opening and closing. I originally thought it was dirt on the bottom rail... but there was no improvement on cleaning.
The broken roller is visible if you look at the hinge on the back of the door. (see the picture on post#5 below to get an idea of what you are looking for)
10 and 12mm sockets. Long socket extension. (probably 6" or more)
grease for rails
EX Part # 72520-S0X-A53 (passenger side)
EX Part # 72560-S0X-A53 (driver's side)
LX Part # 72520-S0X-A03 (passenger side) (thanks to Odyclub member 'Extreme' for LX part no's)
LX Part # 72560-S0X-A03 (driver's side)
In Canada, each part was about $90Cdn + tax. I understand it is about $50US. Go figure....
I just did the passenger side.
Time required -
* For an EX (electric sliding doors) 1.5 hrs without knowing quite what I was doing. Would probably be 45 minutes next time. The major difficulty is loosening the drive cables that are used by the motor to open and close the door.
* for an LX (non-electric sliding doors) - you guys have it easy: maybe 20 minutes.
1) remove rear brake light & turn signal light assembly by prying open two small plastic access ports and removing two phillips screws. The whole assembly pulls straight back - it takes a bit of effort. (picture below is the passenger side)
