Front Polyurethane Control Arm Bushing Mini-Kit - Volvo 240 / 260

IPD Front Polyurethane Control Arm Bushing Mini-Kit on a Volvo 240 and 260 series from 1975-93. 
Clunking sounds when driving on rough or graveled roads, or squeaking noises over railroad tracks and intersections are key indicators of bushing problems.
This kit uses all polyurethane bushings for increased longevity. (Some companies make their poly bushings from very hard material.
IPD formulate theirs for a slight increase in firmness, but not too much to degrade ride comfort).
You may hear this type of bushing referred to as a poly bushing, urethane bushing or plastic bushing.
Those terms are all slange references to the same bushing material.
