Ford Explorer Sport Trac Problem
Average Mileage: 120,691 mi (80,000 mi - 150,000 mi)
www.carcomplaints.com -- This is a dangerous issue with Ford Explorers from this model year. I just paid $800.00 to repair my right front wheel bearing at Koucourek Ford in Wausau, WI. I paid around $600.00 to repair the left front in July at the Firestone dealer near Jolliet, Il. After paying $800.00 I was informed the front left side has failed again. After further research, I discovered this is a common issue, continuous failure is the norm, it is a dangerous flaw, and Ford should recall these models.
Last summer year had to replace brake pads etc. This year had to install right front hub bearing assembly. Still feels rough. Probably others need replacing too.

I have replaced the brakes,rotors,and hubs yearly for the past three years!! It is a JOKE. I feel it is time for Ford to check into a recall on this item. It is unsafe people could get hurt.If I didn't check mine with every wheel rotation it could be bad. I was just told again today the whole right side is bad again. I am sick of replacing these parts...... ;^(
