The cause of the creaking in the forward suspension at the beginning of the movement and the end of the braking may be the protection of the crankcase, which secures the imitator, the longeron and the protection sheet. It is a mistake to assume that the saloon blocks are creaking, so there is no rush to replace them.
It is all about the suspension: the mimic is kept only on two short bolts, and the front is only supported by the bar of transverse stability. The leaves of the sheet are attached to these bolts without any basic protection. Because a node consists of three non-pinned elements, the design is broken and begins to creak. A self-sufficient key can cause damage to threads.
The solution is to dismantle the structure and replace the bolts with the longer. You have to twist the old bolts, then roll the colt on the longeron so that the new bolt can go through three parts. For a gap between the protection and the longerons, you have to put the ghaypuck and firmly tighten the design.
