      Was your vehicle in a accident. If the rf camber is that far out than there is no way they will be able to get your toe Adjusted right. Why did they replace your tie rods? They need to correct the camber in order to adjust the toe. Usually struts bolt holes can be elongated to adjusted the camber in the front. Is there anything bent??

      That big of a thread difference is not good and possibly dangerous depending on how much is actually holding.

    What would cause my wheel bearing or hub assembly on the front, drivers side, to go out 3 times within 1 year…
    This will be the second time I replaced it since I've had the truck. Causes tire wobbles and a squeal before going bad.

      First question - is the truck AWD or four-wheel drive? Next question - when the hub bearing assembly is replaced, is the axle / spindle (bearing contact) surfaces inspected for wear and signs of damage when the hub assembly is initially removed? Any rough surface / wear patch in contact with the new hub bearing can cause the premature failure.

      Next question - when the new hub bearing assembly is installed - is the hub spindle nut (M24-2.0; Hex Size: 36mm) being replaced each time with a new spindle nut - as per the recommendations?
      Also, is the new spindle nut being correctly torqued (not over torqued) during the installation? The correct tightening torque specification is 177 foot / lbs.

      Ecah of these conditions may lead to the premature wear of the hub bearing assembly and cause replacement.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the front hub bearing assembly from around $53.70, and the hub axle nut from around $4.30 for your vehicle.

      Excessive tightening torque on the hub nut.

      Any modifications to the factory wheel size, tire size, wheel offset, or suspension mods can lead to premature wear. If your suspension and wheel/tire package is unmodified then the bearing was likely improperly torqued when installed.

      My Truck does have a large lift kit and tire size but all the problems im having are from the hub assembly on one particular side. As of yesterday, everything on the front, drivers side of my vehicle from. The control arms to the C/V Axle Shaft was Replaced. I have a warranty on the hub assembly so it will be installed new today. And im having it sent in for a proper alignment and rotation / tire balancing also. I believe that the hub I purchased last had a bad seal because grease is heavily showing around the assembly unit. I will try this once more... If premature failure occurs again, im sending my truck to the damn shop for help.

    Why do I have resistance turning left or right?
    The vehicle has 170,000 miles. It was been cared for, but is getting old. Started in last week or so and getting worse. All steering fluid is full and no leaks. No specific noise that is new or unusual.

      Several possibilities; faulty / worn steering pump / serpentine drive belt, faulty / worn drive belt tensioner, faulty / worn power steering pump, faulty / worn steering gearbox unit.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the power steering pump from around $21.00, the serpentine drive belt from around $6.50, the belt tensioner from around $31.00, and the steering gear unit from around $106.00 (minus core exchange) for your vehicle.

    Power steering system
    how do I figure out which hose is leaking, It seems to be the worst as Im back up with a trailer

      Replace both steering hoses at the same time - both the pressure and return hoses - due to mileage / age / wear considerations. Typically, the pressure hose leaks due to the hydraulic pressure and cycling of the system.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the power steering hoses from around $9.25 (pressure hose assembly) for your vehicle.

    Is there a bearing that goes into the fitting that goes in the bottom of the power streeing pump
    It goes from the power sterring pump to the geer box
     
    • Jimm
      2/27/2014 Jimm
      The power steering pump is sealed - has one (1) shaft on the front of the housing for the belt drive pulley. Which bearing are you referring to? The internal pump bearings of the steering pump, or the steering gear box steering shaft (output) bearing?

      Need more detail - better description of the part in question, to be able to offer more assistance.

    Clicking noise from front drivers side front wheel?
    When turning or slowing up to a stop slight roll clicking can be heard. Rumbling noise, almost sounds like 4 wheel drive is engaged, even though it's not.

      Remove the tire and spin the wheel and I believe that the cause will become evident. Bad bearing or loose caliper / missing caliper bolt, loose wheel, loose brake pads or broken brake hardware.

    It is telling me to service ride control.
    It has 130,000 miles and i believe that it doesn't ride as smooth as it used to. It has an air ride assist. What should I do?
     
    • HouseCallAuto

      You probably cannot do anything because you cannot access the air suspension module to read data or fault codes which requires a shop grade scan tool that cost $2000 and up. If you knew what fault codes were stored you could proceed to the next step of testing *maybe*. A very strong possible cause is a bad air suspension compressor but you would not just replace this on a maybe with no data. even in a professional experienced shop, these type of diagnostics are often not a slam dunk diagnosis.

      Other than being installed on the same vehicle, you mean? What exactly is the issue or question you have in regard?
