    Semi truck tandem axle service

    Posted by Corey Adams on Aug 16th 2020

    Lets start off like this. Truckstop wanted to charge me $150.00 per axle. My price was $170 for 10 gallons and I did both axles with 3 gallons leftover for anything else. Just want I needed a synthetic axle oil for my 2007 freightliner century with 40,000lbs tandem axles. Im very happy and I saved $130.00. Took my old oil to autozone and dumped it for free.
