Nice job. Both my front levels were leaking and needed new seals. Had the work done at a tractor dealer who rebuilt both for $100. I did not replace the spring and so far everything is still working great.
Starting to get mine ready for summer season and found my step will not retract. Also plan to remove the carpet from the entry step and replace it with a high grade rubber cap similar to those used in commercial bldgs. Meantime my heater inside the steps quit so got to check on it too. Last time it was just a loose wire. Its like a house...always something to do
