To measure a custom driveshaft for your early Bronco, follow these simple steps:
-
Get the Bronco Ready:
Park your Bronco on a flat surface with the suspension at its normal height. Use wheel chocks to keep it in place, and set the parking brake.
-
Find the Measurement Points:
Look for the fixed yoke on the transfer case and the yoke on the rear differential (or front differential if you're measuring the front driveshaft).
-
Grab the Right Tools:
You'll need a tape measure or a special driveshaft measuring tool. Make sure the tape measure is in good condition and long enough for the job.
-
Measure from Yoke to Yoke:
Measure from the centerline of the front U-joint yoke to the centerline of the rear U-joint yoke.
-
Write Down the Measurement:
Double-check your measurement to make sure it's accurate, then write it down.
-
Think About Other Factors:
Consider the driveshaft's operating angle, suspension travel, and make sure there's enough play to accommodate these factors.
By following these steps, you'll get an accurate measurement for a custom driveshaft, ensuring a perfect fit and great performance for your early Bronco.
