Pandemic caused parts into prolong storage conditions. Empirical experiment was carried out to determine the viscoelastic behaviour and consistency of unworked grease from inside a wheel roller bearing. The grease samples intervals were 9, 10, 11 and 24 months from stored wheel roller bearings. Fresh grease is also tested as a controlled sample. A rheometer amplitude oscillation test was performed. The grease was tested for contaminants such as oxidation, nitration, soot, sulfation, and water using FTIR. Rheology test exhibited changes in viscoelastic behaviour. Grease consistency changed from grade 2 to grade 1. This confirms that the grease tends to soften and degrade over time. FTIR results revealed that there is no significant contaminant for unworked and packed grease in the wheel. Storage and maintenance interval derived from this study.
