The Mueller-Kueps Suspension Wear Indicator, No. 432 910, can be applied onto the steel with a special injection technique, allowing for the inspection of moving parts in the lower suspension of a vehicle on any surface. It eliminates known struggles such as moving wheels in the unloaded condition, specially shaped tire irons, wood blocks, pry bars and etc. It also helps increase workplace efficiency, eliminating the need for a second mechanic to check for other moving parts of the suspension.
