I need to replace all 4 wheels on my Honda Lawn Mower. For the front wheel I selected Part#44710-VL0-L02ZB. The Rear Wheel seems to have 2 Options Part#s 42710-VG3-010 & 42710-VE2-M02ZE. Also wanted to see if the Thermal Wax Assembly Part# 16620-Z8D-842 is correct. Ready to order as soon as I get confirmation... Thx :)

    The part arrived quickly and fit perfect. It was also the updated version of the repair part I ordered. It was fairly easy to install, as I only had to remove the 2 bolts that hold the carburetor assembly in place to expose the thermo wax assembly. Very pleased with this experience, and will order from eReplacement Parts again.

    Good experience! Arrived quickly.
    Replacement takes about 20 minutes. Cleaning carb and gasket faces will add another 1to 1and a half hours to the job. Mower runs like new again, starts on first pull.
