Question: I have a 2023 LT Trail Boss. Do I have an "AAM style/brand" axle? Thanks for any info!
 
Turns out I have GMCH. Any real differences between the GMCH and the AAM?

My truck is an early build and has a GM axle in the rear and an AAM in the front. Also an L82 5.3 with AFM, 6L80 (6 speed) trans and 3.42 diff gearing. Differences in the gaskets and lubricants... Always provide your VIN to the parts guys so you get what you need. 🤙
