    Why does my truck rise after ball joint replacement?
    I just changed both upper and lower ball joints on front right side. When I turn the steering wheel right, the front right side seems to rise a little, only noticeable when stationary. I'm wondering if this has something to do with alignment? I know its an odd ...

      This condition is caused by the alignment. specifically the caster angle. All vehicles with power steering have a small degree of caster designed into the suspension and adjustable at the control arm. The caster angle is what makes your steering wheel return after cornering and maintain straight line stability. When at a stop, and turning the wheel it basically will turn the wheel down into the ground which in turn makes that side of the vehicle appear to lift up. This is normal in most cases. Normally you should have the alignment checked and adjusted after having suspension work done.

      everal possibilities; worn front hub bearing, worn front suspension bushing, loose brake caliper, loose front disc brake pads within the caliper.
      Best to diagnose / inspect with the front wheel raised and supported, remove the front wheel to perform a thorough inspection.

      Reference the 'How-To-Guides' feature on the AutoMD website.

    How do I change wheels and tires on my motorhome
    My motorhome has 8:00 X 16.5 tires. This size is not available anymore. How do I change over to a 16.0 inch wheel and tire? Where do I get wheels? 16.0 tires are available but NOT 16.5! So where do I get six 16.0 wheels for my motorhome?

      Your tire may be out of balance, or have something stuck in your tire. Also, check the lug nuts to make sure all are tight and tire is completely seated on wheel. There may be a problem with your tie rod end.

      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.
