Measuring axle length for VW Stub axle, Micro Stub Axle, or Mid-Board Micro Stub Axle
  • Check your toe in/out wheel alignment.
  • Lift the hub up, so that if it did have an axle, the axle would be at zero degrees, parallel to the ground.
  • Measure from the BOTTOM of the drive flange cup on the transmission to the BOTTOM of the stub axle cup on the brakes. Reference Figure A
  • Subtract 1/4" to 3/8". That is your TOTAL axle length.
  • Check both sides of the vehicle. It is very common to have two different length axles.
  • Now use a PVC pipe as a mock-up axle. Cut grooves 1/4" down on either end into each end of the PVC for your clips. Install your CV joints and mock-up axle.
  • Lift the vehicle so the tires drop down to full droop.
  • Grab your mock-up axle and make sure that you have 1/4" to 3/8" free play. Reference Figure B
  • If you have 1/4" to 3/8" free play at zero degrees and at full droop then you're perfect.
