This is a common problem in the cars of VAZ-2110, and also (and especially!) in the VAZ-2111 and VAZ-2112, in which the trunk is aligned with the passenger compartment (so extraneous sounds can be heard more distinctly). You can get rid of hissing in the area of rear shock absorbers by installing special fillers that you can take from your VAZ-2108. Each rack cabinet is required to have one filler.
