Repair pivot looseness
Fit perfectly in my 2017 Thunderbolt and restored a subtleness to the suspension that I forgot was missing.
Note that if you have grease ports on the pivots the plastic bushings are not used, just the metal ones.
Also be warned that even if you regularly grease the pivots through the grease port there will be dry, worn areas where the grease did not reach - regular disassembly and greasing is mandatory!
