Squeaking coming from the Thruster mechanism is common and can be solved easily in a few seconds. The squeaking is not dangerous or damaging to your SmoothStar so there is no need to be worried!
Unfortunately, we cannot provide this oil with purchase due to the long distance it must travel to get to customers. Imagine if oil was everywhere inside the box!
To fix this problem, tip the board on its side and apply a little lubricant on the front and end of the spring inside the Thruster. Please use machine oil or sewing machine oil which is readily available in hardware stores. Don't use WD-40 as it is too light to lubricate this part effectively.
We provide a spare rubber pivot cup for the back truck with every purchase of a complete SmoothStar. Just like the rubber on the wheels of a car wearing down over time, the pivot cup on the back truck will receive the most wear over time. This is due to the additional pivoting force exerted on the back truck.
Bushings, wheels and the pivot cup on the back truck are all components that can wear out over time. You can easily replace these at home. All spare parts can be purchased direct from the SmoothStar website.
