Two problems related to power steering pump have been reported for the 2000 Ford F-250. The most recently reported issues are listed below.
Turning locks when brakes applied at low speeds. Nearly impossible to park the vehicle because steering is impeded. Ps pump replaced twice without any correction. Believe problem lies in the fact that the ps pump serves as a brake assist pump and is not pumping sufficiently to operate both the brakes and the steering. Condition appears to be rampant as numerous complaints are noted on NHTSA's web page. Should be investigated, possible mfg. Defect.
