Ford F-150 4x4 wheel locking up during turns on Ford F-150

Some Ford F-150 4x4 owners report experiencing issues with their wheels locking up during turns, which can be attributed to several factors. Engaging the 4WD system may cause the front or rear wheels to lock up, making maneuvering difficult. Additionally, after replacing axles, hubs, and struts, improper installation or compatibility issues could lead to similar problems in 4x4 mode. Owners have also noted that issues with the vacuum pressure system, which is responsible for engaging the hubs, can result in wheel locking. Furthermore, problems with the differential, such as a malfunctioning rear locking differential, can cause grinding noises and wheel locking during turns. Lastly, on slippery surfaces, the inside rear wheel may slip during sharp turns due to normal differential action in 4-wheel drive mode. It is recommended that affected owners have their vehicles inspected by a qualified mechanic to diagnose and resolve these issues.
