different speed window motors

[stockfornow]

just wondering if there are different speeds for window motors for a 89 ranger. my grandmother paid to have the pass side motor replaced for me because it was out when i got the truck. both windows go down the same but the pass side window goes up slower. any thoughts?

Try lubricating the length of the center window channel where the regulator bracket slides up/down with some lithium grease (spraying the sides where the glass slides with silicone spray lubricant may not hurt as well).
