We are professional automotive drivetrain and Powertrain new parts manufacturers and remanufacturers. We are dedicated not only to assemble premium quality products, but to go an extra step in many cases. We look for design flaws in the original OEM products and make improvements and updates. Below is what we have done to improve this front axle 4WD disconnect assembly.

 

THIS NEW UNIT HAS BEEN IMPROVED OVER THE ORIGINAL OEM UNIT.  WE HAVE REDESIGNED THIS NEW 4WD FRONT AXLE DISCONNECT ASSEMBLY.  WE HAVE IDENTIFIED THE INTERNAL PROBLEM AREAS AND USED A DIFFERENT ALLOY STEEL FOR THE INTERNAL GEARS AND FITTED THE INTERNAL HOUSINGS WITH PREMIUM QUALITY PRECISION MADE INA NEEDLE BEARINGS WITH UNIQUE TOLERANCES TO HOLD GREASE LONGER AND SUSTAIN HIGHER TEMPERATURES.  WE HAVE ALSO USED A SUPERIOR SHELL GADUS S2 V220 SYNTHETIC LUBRICANT THAT WILL WITHSTAND FAR MORE ABUSE THAN THE OEM LUBRICANT. ALSO INSTALLED ARE SPECIAL MACHINE GRADE 12.9 ALLOY SOCKET HEAD CAP BOLTS TO REDUCE FLEXING OF THE ALUMINUM HOUSING.  THIS IS THE UNIT THAT ENGAGES AND DISENGAGES YOUR 4 WHEEL DRIVE.  IT MOUNTS TO THE OIL PAN.
