Got a Jeep Grand Cherokee or Dodge Durango with a clicking sound when turning, or vibration under acceleration? This front left (driver side) CV axle might be the fix. It's the 66-3732 part, specifically for AWD/4WD models with the 2-speed transfer case. Fits 2011-2021 Grand Cherokees and 2011-2022 Durangos with the 3.6L, 5.7L, or even the 6.4L (for newer Durangos). Specs: overall length is 26 3/4 inches, inner spline is 37, outer spline is 32, male inner shape. Comes as a complete assembly, so you swap the whole thing out. Interchanges with part number 60-3732. Backed by a solid 10-year warranty, which is pretty great for a drivetrain part. Quick note: this is for the left/front side only (the right side is a different part number), and it's for 4WD/AWD only. If your rig is 2WD, this won't fit. Also, if you order more than one part, they might ship in separate boxes. But if your CV boots are torn or the joint's worn, this is a direct, durable replacement to get you back on the road smoothly.
