Repair Masters Automotive LLC in Boulder now is able to provide GM front axles for 4WD & AWD vehicles solving the issues of many vehicles ranging from 2002 models to 2009 models.  Our supplier, Jasper Engines & Transmissions, the nation’s leader in re-manufactured drive train products, is offering complete re-manufactured GM front axle actuator assemblies for 4WD and AWD late-model SUVs. 

These actuator assemblies fit the following vehicles:

  • 2002-2009 Chevy Trailblazer
  • 2002-2008 GMC Envoy
  • 2002-2003 Oldsmobile Bravada
  • 2004-2007 Buick Rainier
  • 2003-2007 Isuzu Ascender

What is different?  The 4WD actuator assembly includes a new electric shift motor installed on the housing, two side gears that spline into the left and right axle shafts, along with a shift fork and collar that shifts the vehicle into, and out of, four-wheel drive. The AWD actuator has a metal plate covering the electric shift motor mount. Internally, the assembly uses a coupler gear that connects both left and right axle shafts together, making the vehicle all-wheel drive.

JASPER uses synthetic grease in their re-manufactured actuators in place of the standard lithium-style complex grease which has better lubricant flow, especially in cold conditions.

In addition, one major complaint from vehicle owners is a squealing, or squalling, noise coming from the actuator. The problem occurs when dry seals rub against the axle shaft. These seals, if not pre-lubricated, will cause that condition when the shaft is turning and at JASPER, all axle shaft seals are pre-lubricated during assembly.

If you are looking for a solution for your Chevy Trailblazer, GMC Envoy, Oldsmobile Bravada, Buick Rainier or Isuzu Ascender, we now have the answer with the re-manufactured rear axle assemblies and differentials of Jasper Engines & Transmission products, simply call Repair Masters Automotive LLC in Boulder and talk to our team of highly trained technicians!  We look forward to earning your business!
