Darrin reported that there was no noticable ride quality issues. He drove it 900 miles to Bowling Green last May with no issues.
There was no body tilt before or after we replaced the spring. Maybe because both side of the spring had damage?
I don't believe that it is an age problem because there are a lot of these springs in service that are in perfect condition.
As stated in the Service Manual, DO NOT use cleaners or solvents on the springs.
