Have Truck Repair Questions? Ask an Expert
Hi my name is***** will be glad to help. Chock the wheels on a level surface, Jack the rear axle with a 20 ton bottle jack, release the parking brake and back off both slack adjuster adjustments, Remove the tires and slip on drums will slide off of the hub. For Bolt on drums remove the nuts on the outer axle perimeter and then thread them on flush to protect the threads. Put a oil drip pan below the brake hub assembly and hit the center of the axle with a sledge hammer to break it free from the hub and the oil will go into the drip pan below. Remove the axle assembly by sliding it out, Remove the outer lock nut, retainer and inner lock nut and slide the complete assembly off of the axle tube. Then you can unbolt the drums.
Sorry about that.What is the year and your VIN if you can provide it? I will have to do some digging on the front hub assembly on this model. I only have a diagram of the updated SIBS style brake.
Hi, Where are you geographically?
I can not access any info for your VIN and model number unfortunately. I am going to opt out and maybe another expert might be able to pull this info up for you.
