Sliding door upper roller bearing

[abehil]

I have a 2002 Quest and the passenger side sliding door roller bearing is worn out. I'm talking about that little 1/2 inch bearing up at the top of the door.

Is it possible to buy just the bearing and replace that part of the assembly?

from the looks of things the part is discontinued by Nissan. your best bet is to either A. call some local nissan dealerships and see if they have anything in stock or B. visit your local junkyard
