Not every video starts as a good news story, and this one definitely didn’t. Two years ago I installed a 1.75" ReadyLIFT leveling kit on my 2021 GMC Sierra AT4 to get a little more clearance for bigger wheels up front. The reality with these 2" pre-lifted GM trucks (2019-2026 Silverado/Sierra) is they’re finicky when you change front suspension geometry, and CV axle angle is one of the first things that gets stressed. I noticed grease seepage and splatter on the passenger-side CV near the transfer case—no vibration, no obvious failure—so I’m calling it early before it turns catastrophic. In the video I walk through a full front CV axle replacement step-by-step on these 1500 trucks: moving wiring brackets and sensors (take a picture of clip orientation… ask me how I learned that), separating the tie rod, popping the upper ball joint, pulling the axle, and yes—ending up removing the brake caliper for the room we thought we wouldn’t need. Instead of going back OEM, I tested an OE alternative by choice: TrakMotive extended travel CV axles (GM-8545XTT), designed to articulate more and handle leveled/lifted angles. After install, I ran it at highway speed and in Auto 4WD—so far so good—but I’m watching full-droop clearance near the shock because those boots can get real close.
