Hello guys and gals. is your sliding door having issues? Well this is what i did and the results are amazing. first thing you need to do is remove the center roller guide from the door make sure to secure the sliding door or it can fall and mess your whole day up. I suggest a jack stand to support the weight and a rope tide to the door piller to keep it falling sideways. Remove the retainning washers at the top with a pair of wire cutters. Now remove the plastic bushing guides. Now you need four 6x9x4mm bearing and two 5mm c clips. install two bearings on each guide post and cap it with the c clips. Now its ready to go back in. FOLLOW THE TOYOTA MANUAL FOR PROPER INSTALLATION AND ALIGNMENT OF THE SLIDING DOOR.
