On the lower portion of the rear springs is a plastic sheath that covers about three of the coils. Is there any reason for these other than to accelerate the rusting of this portion of the springs? Can I live without them?
I have never known why they put the plastic around the bottom few rear spring coils.
i have noticed,on the hoist,that the lower few coils can,and do,rub on the axle housings,and can cause a squeek.
I usually remove the plastic from the rear springs cause i have found rust starts in there and ghave also seen spring break in there due to water getting in there,,rust starts,then they break.
Just remove the rubber,and evaluate the spring coil condition.
