2005 Ford F-150 FX4 8 Cyl 5.4L
Steering & Suspension
Steering is stiff when turning corners.
145000 miles on truck. Truck was parked for 3 days and problem was not happening. Started again after 2 days, now its stiff all the time. No warning lights and fluid level is correct.
Several possibilities; faulty steering rack and pinion unit, slipping power steering drive belt (faulty belt tensioner), clogged / faulty power steering hoses. Check the many different on-line auto parts sources; such as - www.autopartswarehouse.com, www.partsgeek.com and www.rockauto.com for the replacement parts.
