Replacing suspension parts

My tow vehicle and trailer are both 10 years old. I'm wondering how one knows when, and what parts if any, need replacing as vehicle gets older? I'm approaching 80,000 miles on the truck. Still pulls just fine, but I'd like to be proactive (if it's not already too late for that)preventative maintenance. I'm specifically referring to the parts that make my truck a 3/4 ton vs 1/2 ton, not regular wear items like brakes, tires, etc.

  • Most common and dangerous points of failure are with the tie-rods and ball joints. They get the most wear and if one fails you are likely to be seriously hurt along with any passengers.

    On my truck I put grease in every 3,000 miles and the boots are nearly empty when I add the grease.

    Some heavy vehicles have what the manufacturers' refer to as lifetime lubrication. I thought they meant the lifetime of the truck but it actually is for the lifetime of the owner which may be shorter than they realize.

    I've done all the regular fluids, brakes, etc. Just wondering if the rear suspension needs periodic replacement.


    I would check the front track bar bushings and ball joints.

  • Check the bushing on the leaf springs. The bushing should be in the holes (usually brass or bronze) and the holes should not be worn out of circular. If you have shocks on the trailer they probably need to be replaced.
